Feather weight interference

i made a prototype feather weight a a few weeks ago using drill motors along with a futaba 2.4 ghz radio control and a Sabertooth Dual 10A Motor Controller and it keeps getting interference.

what happens is the green light labled status on the speed controller sometimes goes out which makes the robot do exactly the opposite of what i made it just do. so for example if i turn it to the right and the status light goes out- it will then go to the left with out me telling it to and then i have to turn off the power and then turn it back on again to get it back to normal again.

does any one have any ideas? as i have none

This sounds suspiciously similar to what happened to the 10A sabretooth I was experimenting with before the magic smoke came out.

What motors are you using with it and at what voltage?

it also sounds exactly the same as the 25a speedo i had, which was the first one i ever brought and it was a faulty one. what are your dip settings.

The motors are just £9.99, 9.6 volt drill motors running off 2 drill batteries connected in parallel,

and what are dip settings?- I havnt been doing this very long. --do you mean what position are the switches on the speed controller?

yes, and are you using a spektrum controller?

i have this with my cousins feather, it trips out goes mad then turn off and back on and its fine

thats what my first controller did, dimension got me to do some checks, then came to the decision it was faulty, that was on a 25a. since then i have purchased about 3 and never had a problem since.

ok well:

mixing mode switch- is on
Exponential mode switch- is on
lithium mode switch- is off
flip control switch- set to R/C mode(on)

---I just noticed it says if your bot is not invertible the above should be off/down ---

Auto-calibrate switch- on autocalibrate mode
timeout switch- which is switched on

Ive tried switching the time out switch to the off position but it seems to go even crazier.- and i have even less control

and im using a spectrum controller

an easier way to describe it! you should try it with switch 1 down, the rest up. you should also make sure your mixing on the spektrum is turned off. that is how mine is setup and i have had the same setup as you in the past.
