Need help with binding issue / DX5C / runaway throttle Titan 21t

[Davey]

Hoping someone else has had and resolved this issue. My buddy installed a brand new standard rotation Titan 21t motor into his Bomber.

He’s running the stock AE-5 ESC, a brand new Spektrum DX5C as well as the new SR415 Rx.

When he follows the bind procedures, the Rx binds up no prob and the servo works fine, but the second it binds, the motor goes full throttle.

We’ve tried reversing the throttle in the settings, lowering the throttle rate to see if the motor would spin at a lower speed (no change), and have checked the plugs and ports and everything looks good.

Any ideas? He says the ESC was still operational when he put the rig away last.

It seems like the failsafe setting is defaulting to something other than zero/neutral during the bind process, or maybe this is just simple wiring issue, or worst case, a fault in the ESC...

Any ideas? Thanks -Mark

It sounds like an ESC calibration problem. Have you tried recalibrating the ESC to the TX?

Best I can tell from the manual, there is no calibration procedure for when user is using a non-AVC Rx such as the SR415.

They have a graphic in there that shows the typical calibration procedure is only done with AVC Rx’s like the SR6000T.

The only related exception would be if the user were to change a physical feature on the Tx such as installing a new steering wheel, where they would need to then go full throttle, full brake, and full left and full right.

You have to calibrate the esc.
This procedure you will find in the esc manual.

Ahhh. Yes I should have thought of that. Brain drain at 2AM lol. We had been going off of the Tx manual. I’ve got the AE-5 manual pulled up and we will give that procedure a shot. [emoji1591]

Thanks to both of you for the input.
