my contender had the slowest roll rate
it won't snap no matter how throw was increased.
the wing tips were level

however it's still a very great flyer. plenty of other manuvers i used to practice with.
great for practicing patterns. a learnd to go inverted close to the deck with this airship.
flew like is was rails. had plenty verticle with only a .46 magnum.
it did unlimited outside loops. I managed to get 5 consecutive rolls out of it
low stall rate, lands like a kitten. I had a lot of fun with it

the nose wheel mount on mine had bind nuts
the control arm was also soilder to the strut.
used a cylinder type tank
used a 3" - 3 1/4" spinner
