Collective pitch linkage



I replaced pitch slider to KYOSHO's optional ball bearig type. It is smooth. Good for low fliction.
And i use ball link for pitch lod.
Servo is FUTABA S9601, high torque type. I think that, this class (EP540 and GP10-15) needs hIgh torque servos over 2.5Kg/m.
In case of high speed flight, pitch servo need high torque. Because i clashed CONCEPT10 at looping, when i used low torque servos in pitch. Eaven if EP heli, this is inportant.


Pitch Controll Lever

This is easy made lever, everybody can make easy.
It needs only FUTABA's servo holn (large size), and 3*6*2.5 ball bearings(2piece)flange type.

How to make

  1. Shape servo holn as you need.
  2. The hall of servo holn, expansion with taper leamer about under 6mm. The ribs of hall, if it not need, please remove.
  3. Push into ball bearings to this hall.
  4. Use HIROBO's bearing simm (thikness 0.5mm) between ball bearings.
  5. Finish, It's easy!

If you need minisize lever with ball bearings, it is useful.
