This is the OLC, not the world championships. There's no official observer of the pilot or even the type of aircraft. If I set my glider type to a T21 and fly an EB29 I can also cheat.

Why is this standard not applied to jets - often not detected even at full power, or even petrol engines? You can wrap a Nano in some foam and put it in a box and I bet it won't detect a rotary engine.

Perhaps Jeffrey has a suboptimal install, and he should fix that.
