Spektrum fail safe issue

[Allan1875]

Hi guys, wondering if anyone has experienced this problem or has any suggestions?

I recently changed from my KO module in my Espirit III to a SPektrum module. Initially couldn't get the fail safe to work right when binding the receiver, everytime i switched the car on the wheels would spin up almost on full throttle. I solved this by binding the receiver without my transponder plugged in.

Anyway, i thought that was all fine but i have just changed from an LRP SXX TC to an LRP Flow and have encountered a similar problem.

When i first turn the car on the wheels spin for about 1.5 seconds, however it's only like a 5% throttle so they spin very slowly. If you turn the car off straight after and turn it back on they don't spin up the 2nd time. Also if you turn the tranny and car on and ocne the wheels have spun up, if you turn the transmitter off, the car stays still, so the fail safe appears to be working correctly.

Can anybody figure out why the wheels are spinning up?

All the usual things i've checked, trim at neutral when binding etc, have tried rebinding several times. The only thing that has changed is my speedo.

Would appreciate any answers.

Have you calibrated the speedo?

Calibrate speedo to tx then rebind your tx/RX with throttle in neutral

Sorry lads i should have said, i've already done that, i've raced a full meeting with the car.

That's why i'm confused, i have covered everything i can think of so far.

You need to retry in the order I have said.

If you've changed the speedo, make sure there aren't any little bits of wire bridging terminals.......... Can cause some odd behaviour. Not that I've ever done it, *coff coff*

Tried that out of curiosity, still the same. What's weird is, if you sit and turn the car on and off, sometimes the motor will spin up, sometimes it won't and when it does, it's not always at the same speed.

If you turn the transmitter on and off while the car is on, 3/10 the motor will spin up, the rest it won't.

It's an extremely odd problem, i can film and upload to youtube if it's any help?

Can someone clarify as i've tried both ways of binding. Bind plug into receiver, car on and receiver flashes fast. Then turn transmitter on holding the bind button. Now i've tried letting the button go and letting it bind. I've also tried as per Spektrum manual keeping the button held. Both ways it binds but with the same outcome.

I'm kinda stumped on this.
