Default Hitec/airtronics servo trouble with FASST

my servoes are having trouble centering with my fast system. Id like to try to keep the fasst system - wondering if anyone has had any luck with servos in 8th scale on FASST

im thinking of having Hitec mod my hitec servos - putting in a 2.7v resistor to drop them down to the voltage that the fasst receivers run at.

or im thinking of getting some futaba servos

those new brushless futabas look nice - anyone running them? what do you think?

No idea on what your problem could be....is the Airtronics Analog ? that could be the problem right there....as im assuming the Hitec is Digital....as for the Futaba option...i will only reccomend the brushless 9451 for throttle...as ive personally seen the 9351 fail on Multiple occasions on steering duties....couple were gearset's....couple were case failure's......i would stick to what you know.

yeah the problem is only with digital servos.

futaba talks about it on their site - apparently most servos have a 3.0v signal voltage but the fasst receivers operate at 2.7v. this makes it so the servos don't work well or dont work at all with a fasst system

so just get a Digi throttle and you'll be good to go.

I run JR servos with my FASST system and have had no problems at all.
