Need help getting a spectrum remote/receiver to work with an MMP

[MrAwesome987]

I gave my brother one of my Castle Mamba Max Pros and a spare remote I got from an RTR truck (ryft). I gifted him a TRX4 unassembled kit with these electronics.

He has everything plugged in correctly, as far as we can tell. The remote is bound with the reciever, and the steering servo works correctly.

However, the ESC will not calibrate with the remote for throttle control. The remote is a DX3 "Smart". The reciever is an SR6100AT. I have had him try disabling the "brake rate" as well as try it in different positions. I also had him confirm that the throttle limit was set to 100%.

Is this transmitter just not compatible, or is there something we are doing wrong? Thanks!

What motor is he using? Brushed or, brushless? Try plugging the servo into the second channel and see if it works there. Only black and red wires used for brushed motors. https://dzf8vqv24eqhg.cloudfront.net/userfiles/4671/6540/ckfinder/files/Product%20Manuals/Surface/X_Series_Drivers_Ed_Guide_095-0290-00.pdf

From memory, I had to reverse my throttle on the transmitter to get Castle ESC's to calibrate, but I think it might only be Futaba trans/receivers that need that, but could be worth a try?

He is running a sensored brushless motor.

I did have him try reversing the throttle on the remote, but it made no difference.

I had 2 MMPs, and both were waterproofed with RTV. Both are still working surprisingly!
