You can use a 'headloader' which bolts in place of the main blades...basically headloaders are alloy poles with balls on the end...the balls are perforated and as these rotate they are meant to give the same resistance as the blades. The idea being you can run the engine in the heli and on the ground.

Trouble is you can set the carb up accordingly but when you fit the blades and go fly the settings are no good anymore.

The reason is that the headloaders cant truly replicate the true resistance of the blades, as the blades turn and so on, there are differing loads...add cyclic pitch too and it gets a bit more difficult.

Headloaders have their place in getting a 'problem' engine to run, as long as you accept that final adustments have to be made once the engine is running and the blades are fitted.

Not being cheeky here...at all...but bolting to a table will not represent the true 'in flight' loads that the engine/carb have to cope with.

You basically have the carb settings about right with what you have mentioned before.
