Problem sorted picture from the hardest servo test here - as you can see on the picture, i posted all servos directly inside the coil HF cable loop

- Futaba S3001 not even chicken dancing servo gets frozen
- Sanwa 102 exactly same rubbish as S3001
- Futaba 9253 - hard kicks but servo always return quickly in proper position
 

Cyclone S001 and JR NES 511 ABSOLUTELY FANTASTIC - I can turn the servo wire around the coil cable or even touch the source coil, no problem. The servo is absolutely resistant keeping his torque and moving exactly in same way like the engine stooped.

And what made me most upset?? The 9202 and 9252 same result as 3001
Mad mad mad!! I use this servos mostly like probably most people here...

Going to use the NES 511 33*1*39mm for engine
45g 0.26sec/60°(4.8V)
3.5kg·cm(4.8V)

and Cyclone S001 for pitch elev ailer
Model : S001
Weight 42 gr.
Torque : 4.0 Kg/cm2
Speed (6V.) : 0.18 sec / 60?
let see
