|The plane is an ARF model from
Graupner which Monsieur Laplanche is using whilst another model is under construction
Monsieur Laplanche comments:
'Graupner expect the weight of the plane to be 4800 gr, with the RCV90SP I managed
4250 gr. The RCV engine needed some works on the plane to be mounted radially but
when in place, it was neatly enclosed in the cowling, it was a great thing. Running
in on the bench was straight forward, and operating it
in the airplane is the same.
A lot of torque to use large propeller and very smooth when opening the throttle.
Really the kind of engine I enjoy, because you forget it when so concentrated to
control the plane
