Default Top Flight Holy Smoke

A friend had a Holy Smoke delta collecting dust in the rafters, never flown. He tossed a brushless motor on it and I flew it. Immediately it appeared tail heavy, hard to manage. Does anyone have plans for it? I would like to know the recommend CG range. I have the manual but it states that the CG will be located on the plans.

Give me a day or so to locate mine; with a Como 51 mine came out nose heavy and if I remember right the cg range is tight.

C.g. measures 10 3/8" back from front edge of engine bearers(motor mounts), basically from the front edge of the model. make it dead on maybe by using a plumb bob arrangement.

Thank you very much. This will help the first flight go more uneventfully.

Uneventful first flights are a good thing.

While Iwas reading the manual I should also note the main outrigger struts should be bent back to create a nose high pitch for easier takeoffs probably 10 15 degrees nose high.
