engine cutting out
 

The last few times I have brought my Trex out to fly I have had the engine cut out for like 1/2 second and then come back. It happens over and over. And I have to land and call it a day. I cannot see where things are going wrong. Does anyone have any ideas.

What speed controller, motor and battery are you using?

The more info you give us the better answers you will get.

It's the Trex 450 XL CCPM. Stock ESC and motor. So thats RCM-BL25T 25A Brushless ESC and 420LF Brushless motor (3200 KV). And for battery I am using the hunder Power Pro Lite 3-Cell 2100 mAh Li-Po.

You need an RF Supression ring a.k.a. Ferrite Ring, available from Radio Shack or from Horizon.

Wrap your ESC to Receiver wire through it.

Also keep as much distance as possible between your wire going from the ESC to the receiver and the power leads.

That sounds like what happens to mine when the battery is almost dead.

That could be a lot of things...try cycle and charge your pack. Dont trickle charge it. Check your motor also some motors burnt out from contineous used. I give my motor time to cool down before i use it again. Which takes a while. Thats why i got me another trex so i can interchange them between charges..Also move your receiver as far from your motor as possible.

This thing has had like maybe 7 or 8 flights on it. And the battery is charged up prior to flight. I willl try out the ferrite ring. see if that helps.

Almost certainly radio interference. Do what everybody suggested re keeping ESC&Motor as far from receiver & ant as possible--Also carefully check that no bare metal wire on the ant touches the frame, and that there is no play (up & down) on the entire drive shaft & the upper part of the head (if it's metal).

Also be sure the Batt & motor are OK, but it does sound like interference. I had the same problem.
