Crazy Fall E.I. Rebate…

If you have been thinking about an engine monitor, it might be time to give the CGR-30 a look.  E.I. has a current rebate that seems pretty tempting.  $1000 off the basic 6 cyl unit.

The Basic model wont give you the functionality of the Premium, but if you need a simple engine monitor (CHT/EGTs) fuel flow computer this would be a great deal. (also does Volts, OAT, RPM and tach time.)

If you are considering any E.I. unit, please give me a shout as Bushwagon East is an E.I. dealer.

Wing X Install – Part 5…

The install continues…

A word about pulling the rivets. Although the kit comes with everything you will need (and some extras for once) it’s always good to understand just WTF is going on. The stainless strap uses Cherry Max and not just cherry rivets. If you and (God forbid your AP) don’t know the difference, its worth learning.

5a72e5efb9600761f1965465

Before you move on, make sure all the rivets lock. In a nutshell, the stem gets pulled and must lock with the steel collar. If it doesn’t, the rivet will not look flush, and if its not flush, its not structurally sound.

095ceaceae6ce4f9dd6ae6b7

Next step is to dress up the outboard ends of the upper lift strut. Because flush rivets were removed and universal heads were installed, you will have to dish out some material on the inboard and outboard side of the strut in order for the strut to fit back where it belongs… A bit nerve wracking at first, but no biggie as you will be working distal of where the tangs rivet to the strut. Dremel works great here, first with the cutting bit, then the sanding drum.

Remember to measure sixteen times and cut once… You can always remove material, but never add it on.

61d1df316136179dd5e1c67c
Last thing you might want to think about here before you re-install the lift strut is to rehab the tangs. I cant in good conscious re-install a part without freshening it up, so I hit it the part with some scotch bright, z-chromate, and some metal finish Rustoleum.

Next I focused on the stainless strap. Again, this is getting sandwiched between the skins at Sta. 100. Note: This step is only required on SOME models. You will have to check your main spar to see if it is needed.

With the strut out of the way, you can now drill the heads of the flush mount rivets. You will be drilling out the 5’s and installing #6 universal head cherry max. Even though you will be eventually enlarging the holes with a #10 bit, take care not to take the easy way out and just drill out the 5’s. Snap the heads, and drive the tails out with a punch…

c4a02af9d140c082fda1d7fb

With the flushies out, slide the stainless strap between the skins and start spotting. Spot drill, remove, drill press, install, spot drill, remove, etc… Stainless sucks so go nice and slow and take your time.

40f4e33914acd25de3bc8b6a

Once the holes are all in, and everything fits, fit the strap and enlarge the holes with a #10. Remove and debur, then install for the final time….

ac774503ea2ea1f7aa2b9b10

Since clecos wont really pull the sandwich tight enough, I used several #10 fasteners to snug it up real tight. Once you are all set, pull the #6 universal cherry max rivets. The 6’s are damn near impossible to pull by hand, so make sure you have a good pneumatic rivet gun handy.

90896d4da857385b176a7774

One final note… The kit comes with all the fasteners and rivets you will need. That said, make sure you double check the hole with a grip gauge before you pull the cherry Max. The stainless strap will use 6-6’s for all save one. This is where the skins lap. Here WingX provides a 6-7.

Next on the agenda is to get the strut out of the way so you can gain access to the Sta 100 lower rivets.

I use a Genie Superlift as it is perfect. Its manual crank allows for very small adjustments and its fork is just wide enough to lay a small cradle on and grab the outboard wing. It is also perfect for lifting the TW to get A/C into flight attitude for weighing, fuel calibration, or whatever… Once you have the bolt loose, releave the tension and drive out the bolt with a brass drift. It’s tough to get a hammer on the drift, so if you can’t get the bolt totally out, careful not to cheat and ease it out with a ratchet… This will gall the inside of the fork and weaken it.

1f7c99e68dca5ade21d445fa

7be46d5698379bf7a35d2d9b

It’s a bit freaky, but crank the wing up just enough to let the strut end drop out. With the strut free, lower it just enough to gain access to the rivet line.

Lots of places to start, but the first step I did was to cut the access holes in the underside of the wings. The instructions say you can cut as many as needed, but really the job can be done with just two in the right spot. This is not a how-to, so confirm your own measurements, but the holes are roughly inboard of Sta 136 and 154, 2nd bay aft of the forward spar.

To cut the holes, I used the ARC360 from Spruce which is totally awesome. Super easy to use, fast, and perfect holes. No muss, no fuss.

4553f3c837c939aac7f10929-1You may want to rivet the backing plates for the inspection covers at this stage, but don’t squeeze em yet as you will want the holes as large as possible to get your arms in there… and for that, make sure you wrap some tape around the edges of the holes to save your forearms from getting all cut up.

Alright… The Wing-X.

First thing to talk about is just WTF is this all about. Most 100 series Cessna owners knows about it, but exactly what is involved can be a bit of a mystery as there isn’t much install info on the web. One thing is for sure… it’s damn expensive. At $5k for the kit alone, its no joke. A shop that has done em before is in for 40-45 hrs while a first timer may be in as much as 60.

The WingX website claims the additional 12 sq feet will give a 25% reduction in ground roll (on wheels,) a 12-15% increase in climb performance, 1000′ increase in service ceiling, and a GW increase.

WingX

All sound good, so lets do it right?

Bummer is for me, I already put the big stab and Kenmore GW increase on, so nothing there… Increased T/O roll sounds nice though… An easy take off in the wagon is 250-300′, but any decrease is welcomed. A really good crisp cold day with light fuel is about 1700’/min so another 200’/min might be real nice indeed…

Kenmore

For the most part, the general consensus seems to be that for floats, the kit is for sure a winner. For wheels, it gets a bit more convoluted. I’ve tried to do the research, and unfortunately the “been-there-done-thats” that I trust generally say not to install it. I’m not sure if this is because they say it its tough in the x-wind, a bitch to get to stop floating/flying, or just damn near impossible to get inside a regular hanger, but because I own the kit, AND its super easy to take off once the install is done, I’m gonna put the damn thing on and make up my own mind.

You can order it for the stock wing, or as in my case, for the Sportsman. I did test fit the kit while I was doing the Sportsman install and the fit is pretty snug. Paul from WingX and Willie Stene work very closely and have worked out all of the bugs, so I expect no issues due to mod conflicts.

Here goes….

6aeddc900a701fd685c05c5a

First understand the kit breaks down into three basic steps.  1) The stainless strap, 2) the packer, and 3) the tips.  If applicable to your A/C

The stainless strap is used if your A/C does not have the later beefier angle bracket at and around Sta 100 and if you want or are operating above a certain GW. This strap is centered at Sta 100 (just under the strut) and is stuffed under the leading edge skin trailing edge. The bitch here is you will have to unload the strut by lifting the wing and then move it down about 12″. It also sucks ass to drill the stainless… But not impossible if patient. Go slow, and have some extra bits handy. The packer is fitted using #6 universal head cherries so make sure you have the proper pneumatic puller.

e6e2a18455bb1e784ac9b9b9

The packer is made up of two bits of alum straps that are riveted up under the forward spar cap centered around Sta 136. These are aluminum and much easier to drill, but require some modifications to the ribs to get them to fit.

You will need to cut at least two new inspection ports in two bays to gain access to buck the rivets. The Wing-X drawings are God awful, don’t follow standard A/C convention, and have a bunch of confusing illustrations (e.g. large views of the left wing with exploded views of the right.) Might take an experienced sheet metal worker a couple of head scratches and some time to sort it all out, but in the end, it ain’t rocket science. Actually being smart might be a detriment as I’ve seen the less experienced A&P just push thru this install w/out asking the important questions. Their installations aren’t pretty, but they go quickly.

Regardless, I will say that Paul C at WingX is FANTASTIC and will be there (even on the weekend) for support. Top notch customer service IMO. Although confusing, he provides a good and complete kit.

fcb5085e5677019b89af04a9

Last of the three components are the wing extensions.  These come primed and will eventually just screw on like wing tips. Patience here is important as it is fairly critical to get the geometry perfect.

Wing-X Install Begins…

Post was orig published over on BCP.org Feb 2, 2015...

Well we have been slammed with snow here in New England… Just got our hanger plowed out yesterday in time for another 12″ of the stuff today…

b3cc4e3111f29c0c0a43ea2f

Anyway… The non-flying WX is good for projects, so I thought I would start in on the Wing-X install.  I’ll try to do a detailed install report, so stay tuned!

Leaky Bladders…

DSC_3344

If you haven’t heard, probably the least loved task to do on a Cessna Skywagon is replacing bladders.  Fortunately for me, I was happily tapped by fate to take this dive after springing a leak.

Since I started on the resto of the Wagon, I knew that I was going to have to face this at some point, but have been pushing and pushing it off until finally my number was up.

My 66 has extended tanks, which is both a blessing and a curse.  Curse because the tank is bigger.  Blessing because there are two ports to allow just a bit better access.

IMG_0917

First step is pull the bung and drain all the fuel.  (This is a great time to order new sump drain valves and stainless steel safety wire screws)

Next, pull the ports and caps.  Also a good idea to order new stainless fasteners here as well.  On my airplane, the large machine screws are MS24694C48, the small ones are MS24693C293, and the stainless safety wire screws for the drain are AN500AD8-7.

Be very careful removing the screws as chances are they are in there good and solid.  Get some penetrating oil on and let them soak overnight.  Use the CORRECT screwdriver, and take your time.

If your unlucky enough to round out the well, don’t fret as you can use a Dremel and cutoff wheel to carefully make a slot in the head for a regular screwdriver.  Takes practice, but doable without getting into the surrounding alum.  (Just make sure there are no vapors kicking around!)

DSC_3240a

With the caps out, a good idea is to line the edges of the cavity with duct tape to protect both the tank AND your arms.  You will thank me later…

DSC_3258a

With the caps out, take your time and remove all fittings.  This will be fuel outlet screens (forward and aft in later models) crossover vent, fuel sump, fuel sending unit, and outboard vent.

The fuel outlets are the trickiest because they are delicate.  Once out, it’s a good time to give em a real good inspection.  Although not always possible, I am a big fan of replacing parts with new.  The problem with these screens is (like everything) Cessna wants an ungodly chunk of change… Have a late mode bird and you have now doubled that ass raping cuz you need two.

The good news is that Burl’s Aircraft in AK has a fantastic solution.  Their STC’d spun aluminum screens are not only cheaper, but they provide a much better flow rate.  Worth checking out!

DSC_3246

Anyway… reach in the cavity and roll the bladder into a nice tight sausage, and then CAREFULLY work it out the port.  This part sucks for sure, but enjoy it cuz getting her back in will make this part feel like cotton candy and prancing unicorns.

IMG_0721

With the tank out, get her in a box and ship her out.  There are two big places to send out the bladder.  Although their website is cerca 1990, I have had great luck with the service from Heartwig.  Eric is a good dude and worth a phone call.

heartwig

If you weren’t having fun yet, strap it on…

Lots of AP’s lazy-out here because when it comes down to it (you know who you are,) it’s really tough to send the customer a bill for all the time it actually takes to clean and prep a tank bay.  But if you want it done right, make sure you take your time and get it clean enough to eat off.  (Took me 9 hrs of labor to remove tape & clean.)

IMG_0732

Start by pulling the old tape that you can grab.  Heating it up with a heat gun makes this a bit easier and if your lucky, you will be able to get most out without falling into small strips.

Once the tape is off, you will be left with the dried glue.  I find that the best solvent to get this stuff off is called “Goof Off.”  Stuff works fantastic, but a real killer… so make sure you have good gloves and a solid respirator.

 

DSC_3239

DSC_3227

Now that you have cleaned the bay, you can start laying in the new tape.  The point of the tape is to protect the bladder from chafing on corners and rivet heads.  Some think that you can just use Duct tape, but this is not the case.  Tell Eric at Heartwig you need a roll, and he will provide you with one on return of the bladder.

DSC_3276

Laying the new tape in perfectly is next to impossible, so don’t get too bent if it isn’t 100% pretty.  Just take your time, and do your best.  If you did a kick ass job with the prep, the tape will hold solid for another decade and the next guy wont shake his head at you when he gets back in here.

Sometimes they are too far gone, but with some luck, Heartwig will be able to repair the bladders.  They will come nice and shiny and oiled.  If you can, put the bladder in a heated room overnight to get it nice and playable.  You will also want to crank the heat in the hanger.

DSC_3263

Lay out the bladder, roll it up into a sausage again, and start sliding it in.

Once in, lay it flat and start asking Job for patience.  First, connect the snaps (bottom of the tank) to their position in the corners.  Once you have these, patiently work the top fittings, getting the furthest ones first.  Ain’t gonna candy coat it… this really blows.

Truth be told, this isn’t the hardest thing to do, but there is no doubt that this is the most trying task one can undertake.  All I can say is know it can be done.  You don’t need to take the damn wing off, remove any ribs or skins… Just take your time, don’t get frustrated, and motor thru.   Oh… and if you have short arms your F’d.

With the bladder in and all the snaps fitted, go ahead and reconnect all the plumbing, caps, and sending units.  Make sure you use NEW gaskets!  If you are really progressive, you might think about installing new McFarlane fuel sending units here, but I guess I should remember how easy it is for me to spend your money on the interweb.

sendingUnits

If you don’t have a good torq wrench, make sure you pick one up.  It’s always critical, but here, an overzealous wrist can cause a leak pretty fast… And that blows.

DSC_3286

 

At any rate, that’s a quickie on Wagon bladders.  Good luck!

 

 

Cessna Gear Leg Identification…

Night Flight…

Put this video together to show the AeroLEDs landing and taxi light performance as well as the UMA Electroluminescent strips.

Outside: Aircraft has four SUNSPOT 36HX units. Two in RMD wingtips and two in the stock landing/taxi position. DPDT switch is set for wig-wag in flight, and steady-on for final. AeroLEDS NSPs in the wing tips, and Sunbeacon on belly and V Stab.

Inside: UMA instrument bezels, 1.5″w under the glareshield and 0.5″w under the subpanel to light the floor, flap and trim box. Color is White/Blue. There is also a red LED in the overhead that floods the cabin when on.

MT Flight Test…

WX finally broke and I got a chance to fly her today with the MT.

Was a really nice day, sea level, wind 280 at 8 (rwy 240) DA was -800. I was pretty light with 27 gal of fuel, 2170 gross at T/O.

Very first impression? Hard to say… For sure I wasn’t tossed back into the seat with some neck snapping acceleration. Really the biggest thing I noticed right away was the whacky sounding strange high whooshy noise. On the first take off I had to pull my headset off to make sure nothing was going to fall off.  Later on I did a 170 mph buzz job on my friends field and he said it was much much quieter.

That said, I think I’m going to like the prop. I only was able to do a couple of laps around the patch, but although I didn’t feel the A/C accelerate any faster, the data didn’t lie and I was getting some pretty short T/O numbers compared to before.

Of course it wasn’t scientific by any means and just by eye, but with 2 notches of flaps, I was easily lifting her off in the sub 200 range with my best at around 175 ft. I’ll try a camera on the strut to get a more precise measure, but with some more confidence, I think I can do a bit better. Climb out was also a bit better. I wasn’t pushing it, but at 85mph/2550 rpm, I was seeing around 1300ft/min. All pretty respectable for a 180 I would say.

So is it worth it? Yes. Worth the price? Jury is still out.

LandShort

On Goes the MT…

Well, the jury is in… I hung the 2 blade MT on the scale and got the hard number. W/out oil, the 2 blade MT came in a CH above 41lbs. I didn’t weight the spinner/backing plate as I’m prepping for paint, but Im hoping its the same or just a bit lighter than the 4 lb stock.

So all in, it looks like the net savings over the 82″ McCauley 2A34C20390D is only 14lbs, which is a far cry from the 20-30 that gets kicked around the old world-wide-super-web-internet-network. Of course this is still a well needed savings at -45″ of arm so I’m not complaining yet. I will run the numbers tomorrow and see just how much the CG walks back, but all I have to say is the performance upgrade better be substantive, otherwise its gong to be an expensive 14 lbs. Fingers crossed…

Pockets & Antennas…

With the airplane grounded while the gov was out for overhaul, I also got to catch up on some of the smaller items that have been still hanging on the punch list. When Ron Matta at Aviation Creations did my seats, I had him use the extra leather to make a bunch of matching accessory pockets.

Finally got around to mounting the wing root pockets.

First Oil Change & Weight Savings…

Well Im happy to report I just did my first oil change and have 27 hrs on the clock. Still ironing out some small squawks here and there, but overall I couldn’t be more pleased. I’m gonna bang out another 25 in the next two weeks or so after which I will try to sit down and give some honest critiques of some of the choices I made on the build.089a147732e738a8dfdc0dd0

In the meantime, the modifications have in no way stopped. (slowed perhaps, but not stopped) During the oil change today I took the opportunity to install the Sky-tec I picked up at OSH. Sorry bout the pics… just had the damn iPhone.

Saved almost 8lbs at -4.25″. (welcomed as I have a pretty far fwd CG after all the mods, but more on that later…)

Polishing ain’t no joke… After the F9 pass, we still have to hit it with “C,” and then finally “S.” She’s never gonna be a 1 foot beauty, but at ten feet she sure is starting to look nice.

Sportsman Install…

This weekend I was able to get back on the Sportsman install, cutting and fitting the right wing. Everything is now cut and cleco’d with #10s. I should be able to get the detail work done tomorrow/Tuesday. I’m about half way there with the install. Sure is a bitch trying to make it perfect…
