Sinse the last post I have had a conversation with one of my friends at our local field and have begun to use the same conversion technique to electric that he used (Thanks, Augie).
I began by cutting away the floor of the front cockpit, I cut from below and used the formers as a guide for cutting. The next istep nvolved cutting away the bulkhead and bottom supports for the fuel tank but being careful not to damage or weaken the main structure. I used a - very - sharp #11 blade to make multiple score lines where the cut needed to be and then breaking away unwanted pieces and finally sanding it all smooth.
Finally, I measured and built the basic structure for the battery box. After I install fences inside to support the 4 - 4 cell Lipo batteries I'll cut
lightning / air circulating holes. The Stearman will be powered by an outrunner 110 with 85 - 100 AMP HV
ESC & 4 Lipos - 2 in series for 8 cells to give the power a 15 lb plane will need and 2 in parallel for some descent flying time.
