Unrequested full throttle Traxxas Slash

[64Corvette]

So have a problem that happens once in a while (actually once early in a weekly session for 5 weeks in a row now). Usually shortly after we start at our outdoor track. I will be tooling along at maybe 20% throttle and car will suddenly go full throttle. Happens even when I am the only car on the track. Is this likely a transmitter problem, or a receiver issue? I have made sure no other wires are near the antenna. So far it has never done it when trigger is at zero throttle.

Whoa that's sketchy. With the cost of radio set-ups these day...I would chuck the stock radio. For short money vs cost of something going wrong and somebody getting hurt...no brainer. I just had a receiver go bad and lost one channel which was steering luckily. Just my thoughts on it. Traxxas isn't renowned for high quality radios.

I would closely inspect the receiver, mainly the antenna. Make sure theres no damage to the wire. The rx would be my first suspect.

I also had traxxas servos cause a car to go haywire before. So much I dont use that brand of servo anymore.

Thanks, since both TX and Receiver are suspect I am going to replace both. As mentioned the safety aspect worries me most. One time when it happened it jumped two barriers and spun through the air at high speed. Just lucky it was pointed in a safe direction relative to where folks were standing.

Good call. Gotta be safe. Super easy swap.

Make sure you have a functioning throttle return spring and set your radio's fail safe.
50+mph nitros with no drivers are only fun to watch on tv.

Good call on that for Nitro cars. Guess I should not have called mine "throttle" since it is electric.

Does your car use an esc then?
Is that also factory?
I'm not sure if there is a calibration process that might be worth trying before you invest any cash.

You can still mount springs to an electric. They just don't stop the car the same way.

I guess we can all see how my dirty mind was thinking.

A dirty mind is a terrible thing to waste.

Leave it Traxxas to bring back runaways. I thought those days were over when nitro died lol.

I've never seen an electric do that. Except when my new to RC buddy confused ch1 and 2. Oops

I did that once with an overpowered mini Revo. Every time I power up a vehicle, I wiggle the steering to make sure there’s a signal… I wiggled the steering that day and got punched in the chest by a mini Revo.

So just a follow up. I tried rebinding and then speed control calibration. Had another "unrequested full speed" incident so then tried a new transmitter. Since then after about 4 hours of running I have not had any issues. Electronics recycling this weekend for the old xmtr.
