| I'm pretty sure its SR3, but may be wrong.
I believe its better for person setting it up work from scratch as different servo/radio/rx/pushrod lenghts might require slightly different settings. Just a thought!
Just a few tips he might want to consider. Just wanted to compile a few bits which might be useful for someone who's considering CCPM.
1. ATV's for elevator, aileron, pitch must be same. Make sure you dont compromise on 100 both sides. The reason for this is the servo resolution is affected if you decrease the ATVs below 100. (Servo resolution and precision being critical in CCPM)
2. Check the swash throw. applying pitch should move all the three servos in the same direction. if not reverse the direction of the offending servo.
3. When pitch is applied - all three servos must push the swash UP. If not, go to SWASH AFR and change PIT from +50 to -50.
4. check elevator command - swash movement. if its reversed Go to SWASH AFR and change the ELE from +50 to -50.
5. Check Aileron command - swash movement. if its reversed Go to SWASH AFR and change the AIL from +50 to -50.
After the swash throw is sorted set up the pitch:
6. Start mid stick and work upwards - make sure all the horns are square to the servo (Exactly centered). Adjust the pushrod lengths from servo to swash as per manual & customize where required, so that the swash is level. (Note that the elevator arm is in the center of travel in the frame gap.)
7. Adjust the other pushrods above the swash so as to keep the washout arms, seesaw arms, control lever assembly square (Parallel to ground/swashplate), at the same time the blade pitch is exact 0 degrees. (Manual should give almost true pushrod lengths but may need some customization).
Some trimming may be necessary here and there and in flight for tacking.
Don't know if i've missed something or may not be correct. Please suggest any changes. |
