I haven't had any issues yet with the covering peeling off, and I went over both wheels and axles with 3 in 1 oil before first taxi tests, and again last night. So hopefully I won't have that problem today. I plan on heading for the field in a bit! Mine's pretty elevator sensitive, I can't remember my expo. right off hand, but I guess I'll increase it. It shouldn't be tailheavy in the least.
Cheers
