Is it possible to test a heli engine say, a Zenoah 26cc, by bolting the correct size propeller? What would be the equivalent prop size to a Vario Benzin Trainer main rotor load?

The ideal load would be a water pump so you can throttle down a valve and change the load. To simulate the inertia you will need to add a small flywheel. An airplane prop is not so good because it moves air over the engine and that doesn’t happen normally when it is in the helicopter. Something like a rectangular aluminum bar would create the drag and inertia closer to what the heli motor really sees but … but it needs to be balanced.

Again, safest approach is a water pump.

What could be more fun?

Acebird has it right! that would be the best way but why not throw it in your bird and test run it in it? they sell "headloaders" for that purpose. ken
