T/R Bellcrank Position

[Area51]

Hi everyone,

Just setting up my new E7 and was wondering if you are setting your t/r pitch slider bellcrank at 90 degrees with the servo centered and vbar?

Thanks!

I am, works out fine.

I set up mine with 3-4 degrees positive at servo centered, then adjust servo ends in vbar for max throw on each side.

Thanks for the replies. That's pretty much what I did and will get a chance to test fly next week. Can't wait!

The E7 TT tail rotor system is setup for a 5 degree mechanical offset to counteract torque when all bell cranks are set to a 90 degree angle. This is the proper amount of offset to neutralize torque if the heli is placed in rate mode. If you deviate from this the tail gyro may feel sloppy around center. On the E7 TT system, make sure you utilize all available throw both left and right! I've seen many E7's at events lately that are not utilizing all of the right rudder travel which will make the tail performance poor.

Thanks,

Matt

Yep this was me. After converting to torque tube, I left the same 4 mm gap on right rudder you had to with belt version and you're right tail would not hold them right maneuvers.

Reset end points and the tail is happy again.
