Hello all,
New to the site, please be kind!
I am having throttle issues with my twin engine build. I am doing a foam-build replica of ExperimentalAirlines RC-69 Cargo Dropper. As for the throttle issue, all was working perfectly until now, where one motor has instant throttle response, and the other takes one-quarter throw before responding. As you would guess, the instant responder reaches full throttle, the other does not.
My trouble-shooting has narrowed it down to a bad ESC, but I wanted a second opinion before ordering another set of ESCs. Many times with me it is user error!
The specs:
2826/10 1400kva motors
8x8.8 slow-flight props
30A ESCs
2 x 2200 Mah batteries in parallel
HobbyKing T6 radio and HobbyKing receiver
Programmed with T6 Config
V-tail mixer mixing rudder and throttle at 30% rudder travel
How did I arrive at the bad ESC theory? Swapping the ESCs to opposite motors transfers the throttle lag to the other motor as well. I've done this with the servo mixer in use as well as sending the ESCs into the receiver straight through a Y-Harness (no mixing). Throttle trim is just below centered on the transmitter. I've made sure that all receiver wires and ESC cables are clear of battery cables.
When did the problem start? As best I can guess is when I zip-tied (tight enough to hold but hopefully not crimp) wires and cables to keep things neat, and hopefully to keep things away from those they might interfere with, but I am no expert on the subject.
If it is an ESC problem, would you suggest buying a new SET as opposed to a replacement? I'd hate to have one peter out like this in the air on my first twin.
Thank you all for the help!
