Default Worm gears + Super Rooster = no drag brake

Does anyone have a Super Rooster laying around they would be willing to try in the Losi?

Here's why I ask. When I gas it forwards and let off, the worm gears kick in and stop the truck. When I gas it in reverse and let off, the worm gear axles do not kick in. I tried many times. It coasts to a stop.

If this is certain, I might try running the Super Rooster backwards so I do not have a parking brake going downhill, but will have one to help reduce rollbacks going uphill.

I might be crazy. Anyone got a Super Rooster to try?
Towards the camera is forwards, away from the camera is reverse. You can see and hear the coasting in reverse.



I'm gonna wire the thing up backwards and see if it works so it coasts going forwards.

I mean, I have no idea why that would happen at all.

The esc is coasting to a stop, probably part of the programming that smooths out the glitching issue.

Either I'm incapable of running a controller in reverse, or flipping my radio TH channel to reverse and swapping the wires around made no difference. Reprogrammed the ESC a couple times, wired it one way, reversed this, wired it the other way, reversed that. No change. Still coasts only in reverse.

JRH, glitch issue with a Super Rooster? Did I miss something?

Have you tried a different motor in there to see if you get the same effect, it may not be your super rooster but your worm gears?? Just a thought.

Well here is a question: Do the worm gears "push" or "pull" on the ring gear? That just might have something to do with it.

That's what I'm thinking. If they rotated the other way, it might not do it... but might the way he want's it to.

That is weird. Can you push the rig by hand in one direction?

Cory, what if while re-programing, instead of giving full throttle, you go full reverse & then full throttle when it asks for reverse?

Does the ESC have a push control setting?
Worm gears should not coast, at all, ever, due to the design. There's practically no way that the wheels should move unless the driveshaft is doing the moving, or the gears are broken.

It has something to do with the trim on the TH channel. I have the same thing happen with my FXR. Unless the radio is set to (0) before you sync it to the esc weird things happen.
Try moving the trim one way and then the other. It kind of acts like a Push setting .

Ya what he said I knew there was something wierd but I agree......
With that note its electrical...... like the esc or tx isnt centering/going neutral.

or voltage is being stopped slowly at the end like a bleed off of voltage

Hey! Thanks for the input everyone. I've been pondering about this most of the day today, and have come up with diddley squat! It's got to be something in the ESC.

I have tried many motors, as I bought this thing when it first became available and we had to go through what the Losi guys are going through right now. Finding what will at least work with worm gears. Tried everything from a 10T Puller to a 65 turn Integy motor.

Absolutely not.

It's a Super Rooster. No push control, and no drag brake. Nothing fancy, old school Novak. Nothing on or in the truck is broken, I've run it many times with other controllers and motors, and combos of them all.

It's a brand new DX3R radio, and it's all zero'd out everywhere. I thought so also, so I tried various trim settings. Nothing changed.

I'll do it all over again, and change out the Super Rooster for a Tekin FXR since that's easy with bullet connectors. I will reset and reprogram and all that stuff before I try anything. Assuming everything will work normal, as in it will lock up when off throttle, I will then go back to the Super Rooster and make sure it still does what is happening. After that, I will change to a different motor. I have a 35 turn Integy in there currently.

If that tricks the esc into thinking forwarg throttle is reverse, than you'll have the forward roll & anti-rollback. All you'll need to do is swap knuckes & steering to the rear axle & put the lockouts on the front.

Make sense? Hoop it works.

Dumb part is the chassis is not the same front and back. Otherwise I'm right there with ya.

Alright, so the first thing I did was change the ESC to a Tekin FXR. I got everything on bullets so it was easiest.

Alright. WTF? The FXR acts the same way. It's got to be the radio. Brand new DX3R. Everything is at zero. Trim some forward in it and it still does it.

As of now I'll stop caring, or swap the motor, or try my DX3 again.
