I've had 3 of these that fly great and 3 that didn't. One of the ones that flies great is in a tree until next Winter, I think. It's WAY up there. I've brought 2 of the ones that didn't fly great back to Target but not this last one. I do the battery mod on all of them. This last one has a Tx or Rx that just cuts out intermittently and all the ones that don't fly great can be made to fly straight by trimming with the trimming knob or the rudder and elevators. The problem with relying on trimming the rudder and elevators is that turning in one direction makes it dive fairly quick. I first set it up so it glides pretty straight, then trim the motors under power. I'm wondering if there's something else I can set, like the motor angles (left/right or up/down) that will stop it from diving. I suppose it's no big deal as long as Target has a supply and keeps taking them back, but I'd like to figure it out.
The ones that fly straight with the trimmer knob centered have the best climb performance, probably because both motors are working at their fastest speed.
Any ideas on what else can be trimmed?
