I'm building a Hirobo Cap 232/15 Nitro, The book says to balance the aircarft so the CG is 30-40mm from the leading edge, so far in building i have not used the manual. The placement of my equipment is based solely on my previous knowledge of building. I don't want to find out i have an airplane with a CG out of limits the first time i fly it. I hear the CAp is a very snappy airplane. How can i ensure my self that i have a forward CG, but not too far forward for the first few times i fly it. Anybody have any techniques or calculations to figure this. Is it necessary to buy a CG machine for balancing.
I have sent you a spread sheet all set up for your problem. If you can open Excell spreadsheets then this will be all you need. Just don't change anything except the valuse in the cells that pertain to inches,millmeters, etc and the weight values as they pertain to your aircrafte in other words if you use metric values then use all metric, you can change the cells from metric to inches just by typing over the metric values in the cells. But make sure you do all the cells.
