RE: Venus 40 balancing question
Tycho,
I have a Venus 40 with an OS50SX. My 1650 mAhr battery is in the compartment under the fuel tank and the plane is blanced per the manual. I do have the engine in the updated position since I built mine last August.
With the Cg in the recommended location, I find this plane fairly easy to land compared to some of my other aerobats. Just keep a little power on until it settles and it shouldn't bite you.
