Problem arming kk2.1.5 and esc calibration


Junior Member
Hi I am setting up a kk2.1.5 on my hex rotor.

Turnigy 9x transmitter and receiver
stock kk2.1.5 from hobbyking
stock turnigy plush 30amp esc
multistar 2213-935 motors

The problem I'm having is that no matter what I do I cant get the throttle to zero in the receiver test, the lowest it goes is 15. when I push down on the stick it goes to zero and says idle but when i push up the highest i could get it to go is about 60 no matter what i did to the subtrim. I am assuming thats why it wont arm because the throttle is at 15 not zero. also when I try to calibrate my escs i hold down buttons one and four and it enters the calibration mode the escs just constantly beep. they dont beep once so I can then move my stick down they just keep beeping and I have no way to calibrate them.

If anyone has any suggestions that would be great.


I'm a care bear...Really?
You need to go into your radio and drop your throttle in the subtrims. That's where you zero everything out using the receiver menu.
