BEC and Steering Mystery

[Harvo]

I installed a CC BEC on my axial today just like I have it on my Berg. It's the typical wiring where you get the servo signal from the reciever and the power from the BEC goes straight to the servo. The Orange BEC wire is abandoned.

Now the Tekin will run 3 cells fine with no overheating, BUT

At half throttle, the steering locks in whatever direction it was in when reaching half throttle.

At crawl it turns fine and at full throttle it turns fine. Just sticks at half throttle.

The servo is a 645MG and the BEC is set at the max rating for that servo. (6V I think)

Any ideas whats going on? If I can't get it worked out, I can always wire it as per CCBEC instructions, but will the Spektrum S3000 be OK at that voltage?

Thanks

When i installed mine i disconnected the red wire from the esc not the bec.

That's if you are runing the BEC through the reciever. I'm going around the reciever and just using the signal wire from it.

Now if I switch to running it through, I will disconnect the red wire.

I would check with Spektrum product details about the max input voltage to the rx, but I would assume that it too, like many others, is designed to run at 6V. Just my 5g of copper plated zinc...
