RE: 1/4 Scale Balsa USA J-3 Cub
Roger, I am well aware of mixing different capacities will create big problems. I was talking about two 3-cell packs of either 5000mAh or two 3-cell packs of 4000mAh hooked in series, but didn't mean I would mix 4000 and 5000.
As it is, I did a cost analysis for electric conversion, and found it cost prohibitive. So I am gasifying the airplane. I dislike glow power with a passion. Just too messy. With the gas version using a 26cc engine, I can swing intitially during engine breakin a 16x8 prop, and then move up to an 18 inch prop. Can't remember what the gentleman said the pitch was, but he said it would fly slower and more scale like with the larger prop, and be very close to the correct diameter of a scale prop.
Thanks for your concern. But I just cannot afford over $1000, which is mostly batteries. Caley
EDITED: If anyone else is going to electrify a BUSA J-3 Cub, go ahead and use this thread. I am on another now that is for gas power.
