[boa721]

@8ackbar that is your opinion, but thanks

[SanderP67]

I remember lusting over this and other Graupner engines when I was a kid. I don't know exactly how old I was but it must be 30 years ago or so.

[boa721]

yes it is

Is this a rotary engine with only one rotor? Works pretty nice. Of course an engine with only one rotor which is doing intake compression power & exhaust all at the same time. Awesome engine..

[boa721]

I beleive it is equal to a .46 to 50 size engine.

[ramicaza]

[ramicaza]

[ramicaza]

OMG so cool! Never see a little Wankel before! Nice!

The OS Wankel is build for high rpm not high load.

9x6 is OK but 2 blade Prop is prefered (max 10x6).

On your video the motor decelerates a couple of seconds after

full power and that is a sign for torque overload or

too less oil. You need at least 20% Oil on this motor.

I love it how some engine companies think outside the box....... Im pretty sure OS made a pulse jet too.... Itll be great once boxermotorrad gets his act together and starts mass producing the V-12!!!!!!! Cant wait!!!

[BrianRIrwin]

Impressive...that engine is ancient! I don't think there are too many of these engines running these days. I don't suppose that spare parts are still available for this engine?

[Bamchucknorris]

great throttle response :)

[Valentino319]

[douro20]

.3ci or 4.9cc

[boa721]
