The engine I received from Robert HIRSCH is one of 10 prototypes a few top pilots .. I'm not one of them ....are testing.
Without soft mounts and rear support, the weight of mine is 555 g.
The final weight of the engine including 4 soft mounts will be around 510 g, red anodized, and more sexy than the preproduction engine.
There is no adjustable tension device, belt is oversized compare to the OS BELT DRIVE, there are bearings where needed, and it looks maintenance free ....
It will soon hit the market - ask Mike MULLER at F3A Unlimited - after intensive flight tests.
