I need about 10 mins duration to get me way on a decent day...launch at 100% then back off to 2/3 for the climb. About 1500 ft agl will do. I'd have two sets of packs - I never take more than two aertotows.
Setup is believed to be 14S from two 7S packs.
I'm not familiar with really powerful plank setups. I'm amazed at the performance with such a small prop!
IC versions of this mount the heavy engine near the feet and the tank on the control frame and use a much bigger prop and then need some complications to ensure clearance for the prop. This changes the balance of the harness so the pilot is much further through the control frame making it not so nice as a glider. This setup looks a lot nicer and simpler and would be a practical self launcher - but no good for flying as a powered machine from A to B due to the duration. I am only interested in using it as a self launcher.
I'm thinking some protection ort a backup wire might be a good idea as the lipos are right next to the nylon webbing suspension strap! The harness has a carbon support plate in the back so the pilot wouldn't get burned but its more important to stop his hang strap being hot knifed in a battery/ESC malfunction!
