Hi everyone, I just bought a mbx7tr, what kind of springs are you guys using on a loose track? or should I stay with the ones from the kit?

Does anyone know if the 8ight T wing can fit the 7TR?

Can anyone tell me if it's normal for the bottom brake cam to a little harder to move back and forth than the top on the 7TR? I noticed it was like that once I had my servo horn slightly tightened. The top cam moves freely whether my horn is loosened or tightened all the way down.
In the pic the servo horn is nowhere near completely snug. It's as soon as I put the horn on the servo that the cam rod gets snug.

I decided to just remove the linkage all together to see what was actually going on and it turns out that the rod is rubbing against top of the eylet. Could this be caused by the Hudy servo horn that I'm using? I can't figure out why the bottom rod would be binding and the top one is completely normal.
Edit: I repositioned the rod on the servo horn to the hole closer to the engine and it helped free it a little but it's still snug and nowhere near as free as the top.
