Twiin T120 Rivercat problem

[sampit]

I have just finishing building a twin front motor mounted Rivercat with 3126 1600kv outrunners 2 x T120 esc's using 2 3s 4000 mah pack in series for 6s
I set both esc's up independently before parelling them set both esc's throttles independently
on the bench test all powers up ok.
I have set the props to run outwards, problem is when I pull the trigger all looks ok, but when I release the trigger one motor stops dead around a second before the other that slowly stops as i would expect
I not sure if that right, seems kind of odd anyone point me in the right direction?

I am curious too Sam.My Shocker with TP inrunners and Swordy 200's does the same thing.It is my first twin so I could have missed something.

Sometimes you have to play with the throttle trim to get them both to stop. Check and write down settings for both and see if something is different.

I use a spektrum remote and adjusted my trim. I run my packs indepently.

Hmm strange I have the exact same setup as Sam, mine did the same but only because on of the cans was touching the hull as it spun, is there any binding on one of the drives? Do they both spin freely?

Take off the red wire from the one esc.
Use the bec from the one esc.

Trouble shoot.. Can be different problems;
-One motor might have more drag than other
-timing might be diff.
-check all wires and re sink just to be sure

Thanks for all the comments Guys, turned out that one of the strut bushing was a little tight,fixed the problem by reverting back to a single setup LOL, just lost my rag with it today, and pulled it all to bits,
one of the motor mounts needed a bit more resin to hold it in tight to stop it vibrating badly, I remember now that I needed to do this when I bought some more resin,totaly forgot, as its been a long time since i fixed the mounts in, oh well! new plan Fantasm twin on the way soon.
