RE: Questions on an OS 160 engine
I don't have any detailed pics but here she is.
There's a 2000mah battery up front for the ignition and a 2900mah rx pack right behind the cg, the fuel tank was moved back to the cg, weight is 12lbs 6oz zfw
As a former glider pilot, I detest adding weight to anything if I can at all avoid it.
Balance is at 6 1/2" though I probably need to move it up a bit till I get used to it.
