Hi, guys.
I was browsing some old threads and came upon this one on the N40TT. All I can say is that I got 105 flights on mine as a learner to R/C and it was one tough little guy! I instinctively shot some CA around the motor mount area from the git-go and it survived all those flights. On the 106th flight I happened upon a tall tree that seemed to object to being rammed by this "gnat" and I figured after all those flights it owed me nothing. It taught me how to fly and I appreciated that.
The wing remarkebly survived all mishaps and the worst damage ever experienced was holes punched through the covering. I found that Lepages House Hold Glue 4 fixed the covering without melting it and shrank tight and clear as it dried. Clear packing tape that someone mentioned, works well for any skin damage I found.
Well, off to the field! I am trying to get my 1/3 scale Sig Spacewalker dialed in for it's first flight. It is powered by a ST4500 on gas with Prospark bolt on. Runs super on the ground thanks to Duarte Gabral.
Happy landings!
