The hely has arrived to me very dirty. After a fast cleaning now is almost in like new conditions. A Webra 61 engine has attached to mechanic and his piston is just perfect. I will change his old JR 4041 servos and i will try it in the air.
I bought also an original Kyosho muffler for scale body and a new Concept 60 SR canopy with SR & SR II decals.
At those years no 120° system on cyclic servos. So only one servos for move pitch.
