RS10 ESC Tekin Fx-R problem?

[Crawlinyota]

Ok so i am a noob to these new Tekin FX-R ESC's,
Here's my problem,
I soldered in my new Tekin FX-R,
Wired everything correctly with the capacitor.
first try it would "jump" when i throttled it.
Now it jumps when i go in reverse? And only after i stop completely. and hit the trigger six times then it might go in reverse.
So reset or calibrated it with the mode button.
Still having issues with reverse!
Sometimes have to wait a few seconds before it will actually move in reverse.
Still using stock reciever and controller.
stock motors on 3s Lipos
Love em by the way.
Also on my first run today.....
truck took off after i ran it fine for a few minutes. Just shotoff going on its own?
Turned everything off and back on and was working fine except the reverse thing.
Hoping someone had some input on this weird problem.
I just ordered the hotwire programmer.
By the way stock motors on stock reciever, with only one FX-R ESC. No dig switch.

Thanks in advance for your input!

To get rid of the reverse delay, that's in the programming of your fxr. Check your manual it will tell you how to get rid of the reverse delay.
If you don't have a manual check there web site. You should be able to do this without the hotwire.
It will be under your reverse options.
