Hello all!
I'm having a strange problem with my T-rex 600 EPRO. I can't seem to figure out what's wrong with it.
Basically, when I throttle up very quickly, I hear a terrible noise. It sounds to me like it's nylon slipping/grinding but I do not want to eliminate other possibilities!
Here's what I've done to assess the problem:
1. Noticed some bad wear on main gear and tail gears, replaced all nylon gears in the central portion of the heli. Took the heli outside and accelerated rapidly. TERRIBLE noise.
2. Isolated motor and reproduced the rapid acceleration on the bench. NO strange noise.
3. Removed blades and allowed motor to turn main gears and tail. NO strange noise!
So, it would seem to me that there are only two possible theories
1. The motor is making awful noises when under high load. It is an align stock... yuck!
2. Up force generated by the blades is forcing the nylon gears (or something else) to bind. There is very VERY little slop in my main gears, so I'm unsure of this theory...
Has anyone else had this problem? Any help would be greatly appreciated!!
