RE: Great planes ultimate 160
About the only 3d that I do is with a foamy.... and I bust up a LOT of them. I keep a VERY close eye on the servos. I've got one 5645 on every aileron, and the ones on each elevator half have been changed over to the metal sets, so even if I do lose one, I've got some backup. The rudder has the 5955TG, so it's pretty much bullet proof. I agree with you, and would never use them on anything heavier or faster than this, and to be honest, yeah, i'm a bit nervous about them. But that will get changed soon. I've already got the gear sets sitting in the shop, just too busy to pull the servos out and change them
