Default How to fix my drag brake problem in my MBX6T?

So I have a bad drag brake problem in my MBX6T. If I try to trim out the drag brake, I no longer have any REAL brake. And, my throttle servo is making a lot of noise (digital) because apparently it's straining to stay centered. So I need to figure out how to fix my drag brake problem, and put less strain on my servo...

How do I go about getting my linkage set up correctly? Seems like a pain in the ass.

Depends on your radio. You can adjust your subtrim to move the servo and get the drag off, then set your EPA to get more throw in the brake direction.

Take the throttle servo horn off the center you're trim and subtrim then reinstall the servo horn and adjust youre endpoints for the brake and throttle yout might have to adjust the throttle linkage so that the carb is closed all the way and you're brakes are fully released when the servo is centered at neutral

I had a similar problem with the mbx6 where at full throttle my brakes were dragging, it makes it really hard to get fuel milage lol. I ended up cutting the fuel line on the linkage to about .25 inches and going out one hole on the servo horn. This also made it so that the linkage doesn't hit the tank anymore.
