Hoping someone else has had the same problem. I can't get the auto start system to work. I'm running an FrSky 6ch rx on a Futaba T7, my usual set up. When everything is connected up as it should be the auto start won't work. The auto start esc is plugged into Ch5. If I remove the plug from the rx and connect the lead to a servo tester the auto start works. If I connect a spare servo to Ch5 and flick the nominated switch on the tx it works. I have upped the end point on both sides of Ch5 in case the esc isn't getting a clear enough signal and still it doesn't work. So something is going wrong between the rx and the esc.

Any ideas?

You need to use the BALANCE plug... This is what runs the main blades. The front motor goes into channel 3wink

Yes, I know. Everything is plugged in where it should be.

Is the ESC not arming because it's initially not getting a zero signal?

Have you tried plugging the autostart ESC into the throttle channel to see if it works there, if it does it means that it's not arming when it's plugged into the other channel (does it need reversing?), if it doesn't work in the throttle channel, and the main ESC does, there then there is a compatibility issue with the autostart ESC and receiver.

Frank. That's about the only thing I haven't tried. I'm taking it to the patch today and will try it.

One more thing you could try is plugging the main motor ESC into channel 5 and see if it works there, if it doesn't then the issue is with the Tx/Rx not sending a pulse signal that allows the ESC to arm on channel 5

Note it should work I have a G2 (but with my Multiplex Tx) and the auotstart works fine, I have mine on a pushbutton but a switch should work equally well.

I've just put mine together, and noticed the pre rotator motor would not always work, after a few goes unplugging and re plugging in the battery, (inc the balance lead plug) it would start again, you can see the flex on the shaft for the intial loading so I think after a bit of use it will work everytime - time will tell I guess !
