Does any know the correct CG from the BVM electra?
i dont need the "theoretic"CG but the more practical CG.
most of the time its it more or less a inch difference with many BVM products.

Why not call BVM .
SF

193 mm/7.6 inches aft of the leading edge.

like i said
i have owned a few bvm models
and they all had different cg positions
i know where the original is , but as with all their stuff
they seem to fly better with a bit aft CG

The position in the manual (7.6") is a safe starting place.

Simple solution.....For the first few flights, use the CG position stated in the manual. Then move the CG aft about 1/8" or 3/16" at a time as you become familiar with the flight characteristics. Stop when you find the position that suits your ability and flying style.

Sandor since this is the suggested CG for the electric setup.
I would think it is a very good setup as the electrons still weigh the same at the end of the flight

Hmm! A well thought out answer Electric Bob

mm true

i will go a bit aft...
lets see how she goes

Sandor is used to me helping him with a good position. Not any more though!
