Block Island, Lunch, & the L.I. Coast…December 3, 2012
Another great day of flying here in Eastern MA. Got 2.5 done and flew down the Long Island coast to check out some of the damage from Sandy. Turned around just south of Montauk (KMTP) and then up along the coast at 600′ at 80mph. Hit Block Island (KBID) for a yummy veggie burger (with bacon) and then back to Plymouth (KPYM.)
Was able to get a good sense on the performance with the 8.5×10’s and Great Lakes Aero bubbles vs/ the 6.00×6’s. Prior to the mod, I was seeing 145 mph at cruise. By no means is this scientific, nor did I try too hard to get the parameters the same, but today I averaged 140 mph. Pretty much what I figured with the bigger tires.
I also think I got the tire pressure in the “sweet spot.” During yesterdays grass work, I felt way to firm on the grass. On my C170, I would run pretty light at 12psi. Since it was real light, there wasnt much deflection in the sidewall, and it was nice and comfy off airport. Prior to TO, I air’d down to 14psi (from 20.) I will have to do some more testing, but it feels much better.
