Default Auto Pilot Servos Dynon

Getting ready to order my Dynon servos, but not sure which ones.
Options are: Standard Arm, Long Arm, or Capstan

Your input is appreciated.

I have two sv32 servos with standard arm in my -6. Dynon recommends the long arm for the roll, but i have not needed it. The dynon ap74/d180works pretty well with elevator servo set at 100% torque and sensitivity at 7. The roll servo set at 50% torque, 2 degs/sec and sensitivity at 5. The autopilot does not hold heading well in bumpy air due to the small tail of the -6 letting the heading wander around. When the ride is smooth, it works good. The nav mode, coupled to an ifly 740, will take you directly to the airport everytime.

I read it a bit differently....

The long arm is on the roll servo and that is what I used. There is a lot more movement around on the roll servo linkage when it is under the seat.

I made my own brackets but followed the basic Dynon pictures in the above instructions.

Garmin, too, furnishes a long arm for the RV-6 roll servo, which was mounted under the pilot's (or copilot's) seat.

Be carefull here. I am not sure you can get away using the short arm when installed under the seat without getting dangerously close to the roll over point on the servo arm
