Gasser Model RC Helicopters > JR 770T/8900 combo

My new gyro and servo arrived Friday.I fitted it following the simple instructions,which seemed very brief,usually not a good sign.I took the heli(Robbe Millenium gasser conversion)to my flying field for a test flight.It was absolutely brilliant,worked and performed all day with no further adjustments.This is the first time i have fitted a gyro without having to play with the settings.Thanks for the advice from the members of the gasser forum.

A friend of mine was having trouble with gyros on his gasser, he bought a JR combo from china and was well impressed with it and said exactly the same thing about setting it up as you have, when I convert the 700 I will be using a 770T/8900.

What voltage are you running your JR770/8900 at? Just curious....I believe this combo is rated for 6v so it might be an option to run it off 5 cells or A123's without a stepdown.

P-Gasser Se, Raptor 50 Se Hyper, Raptor 30v2, Trex450se, 3dx450...

I am running mine on a 11.1v lipo through a 4.8v regulator.Run a GV1 governor,can fly allday no problem.Got my regulators from J Perkins.
On a new charge it delivers about 5.2 volts ,i dont know if i would want to exceed 6 volts on my gyro/servo.
