Could anyone tell me the best way to set up the COG on this plane?

After reading the posts on the Zero I am setting the centre point on the bamboo spar ~45mm from LE. I have made up a crude balancing jig out of scrap balsa and have the plane sitting on a ~5mm edge. Does the part of the jig where it meets the bottom wing have to be less than this 5mm ? Does it need to be a 'point' like a pencil tip?

Also, I am having trouble balancing the plane. It seems that I can make it go either way, to tail or to nose. How are you supposed to balance it? Do you hold it horizontal in the jig and let go and continue moving the weight (in my case the batt) to and fro until it stays level?

Last question, the AUW I have measured is 16.6oz. I'm using the stock esp300c motor with kan1050 8 cell and stock prop and 20amp esc . With this gear and weight , what flight characteristics and flight times should I have? Gentle circuit flyer, Mildly fast acrobatic?

Any feedback greatly appreciated.

Thanks Raven.

I balance my low wing planes inverted. To include the GWS Corsair I have. I measure back from the leading edge of the wing and make a small mark then flip the plane upside down and place my fingertips on that spot and then balance it. I do know that with my Corsair the recommended CG made the plane tail heavy. Not good. Had to add a ton of nose weight to get it where it would not tip stall on me. I think personally the GWS planes in general are a little more user freindly with a tick extra nose weight. My buddy has a zero and I think he used about a 1/4 oz nose weight to get his stable.

I would guess around 15-20 minutes flight time with that setup. You should be able to do loops and rolls with it. My biggest problem was breaking props and bending shafts until I got the hardened shafts and the adapter from e-flightline and started using the APC props.

Good luck.[8D]
