TEKIN FXR help

[JON0529]

Hi guys, hope you can help me with this. I have a Tekin FXR powered by a 3S lipo, with Novak 45T motor and Hitec 5955TG. Now here is my problem, when i go to full throttle for seconds, and return to neutral it slowly crawl backward. What would be the cause of this?

Another question, Is 3AMP External BEC enough to drive my servo, Hitec 5955TG? Or should i use a BEC with a higher amperage. Thank you very much.

i think you need to adjust your radio settings.

i adjusted the subtrim. I made it +20 on the throttle side. It stopped crawling backwards after full throttle. But after some runs, the problem started again. It crawls backward.

You need to calibrate the ESC to your radio. After power up and ESC arm, hold the mode button until it beeps. Let the FXR find neutral, *beep*pull full throttle *beep* and finally pull full reverse. Do this with all radio trims at 0%. Should solve your problem.

As for the BEC, you should look at something more than 3 amp. The FXR internal is 5 amp; IIRC. Something similar to the Castle BEC is perfect, 10 amps.

my instruction's say .....6v..3amp.... for the FXR....

you need a CC bec that has a 10 amp rating.......

Do this with the throttle trim @ 0 and the EPA's at 100%.
