Sudden Brakes?
 

I notice it when I am at WOT, release the trigger and as the truck is coasting to slow down, POP! The brakes seem to lock for a fraction of a second.

What causes this?

I forgot to add that I have a 9920.

did you try reprograming the controller?

Next thing to do on my list.

Should have been the first on the list ;)

Yes, it should of been.

So it's fine now? Got it fixed?

Let you know after the front diff (pinion gear) is replaced:mad:

Ya thats happening on my 9918. I what to reprogram it when I get my Mayhem center diff in for my e revo. How do you reprogram the controller thought.

After reprogramming the controller , ran it on 12 cells, and it did it again. Attached is a pic, it may be worth a thousand words!

explain exactly how you are programing it.

Per Mike's instructions in the .pdf file. The system runs normally except for cogging (only at the slowest speed), and the brake glitch when I release the trigger at high speed. It accelerates, coasts, and brakes as normal.

BTW, not everytime I release the trigger at high speed do I have the problem, only about 2 times per set of batteries.

does it go into cartwheels, ect?

No, just a real quick "POP" followed by a nose dive.

Would you be able to try a different radio system just to eliminate that as being a possibility?

Do not have one as of yet.

you might want to check the radion in another car or check the antenna on the rx

I agree, it sounds like a radio related issue. The controller will act this way if it temporarily loses signal. Do you notice it more towards the end of the run?

It does seem to happen more toward the end, but it will also happen some throughout the run.

If it is a radio issue though it seems a little strange that it doesn't happen on throttle aswell.Does it happen more at further range particularly towards the end of a run?

Installed new DX3 radio, same problem.

Solution: Center chassis aluminum skid plate was rubbing my Gorilla Maxx aluminum single speed tranny. Replaced it with a plastic chassis brace, no more problems

okay, it was a mechanical problem then..

No, I think (correct me if I am wrong) that the 2 pcs. of al. rubbing caused some type of interference.

which was a bit hard to filter from your words.... ;)

I thought metal on metal interference wasn't possible on 2.4 Ghz(the dx3)?

hmm - sorry to bump it - but would this problem be able to be solved withOUT getting rid of the alum part? Like - could the two parts be coated in something possibly where the contact is being made?

Just curious to know what other solutions could be possible in case it ever happens to me at some stage through - whatevers -lol-

could you place something between them. Maybe file down one of the parts a little bit so it don't touch. Or maybe a combo of the group.

thats what i was thinkin - maybe like some sort of semi kinda-stiff, thin foam piece? :)
