Yes.......definately use 4-40 rods and ends. Throw all the 2-56 stuff in your spare parts drawer. Also keep the slop as little as possible on the control surfaces to reduce the chance of flutter. I used ballinks on the servo arm on all my controls.

Also the new 5475 digital servos are "value priced digitals" they're only about $5 more than the HS525MGs and $8 more than the 605BB's.

Best of luck...............Mark
