Hi all again. So I have just finished my second 1/2a plane for a beam mount engine, and will be using a TD. This will be a first for me actually running a rotary engine on a plane rather than the bench. Anyways, I am needing to find out the line length required to fly these planes on. The 3 I currently have are 22" wingspan up to 28" wingspan. All are profile fuselage and wings. They are just for fun flying, no competitions, and I would like to use some braided fishing line. I will be flying these by myself and will also not be involved in any combat if it makes a difference. So far to date all I have flown were standard 1/2a planes with solid wings and Cox reed 'Bee' type engines, so have been using 30-35 feet of the mentioned braid and string. Thank you.
