This is an enlarged version of Al Foot’s Twin Twirl from 2006, with some changes. It has similar fuselage doublers to the FT Twin Twirl, and has cutouts for a 2 layer thick wing and h-stab. I haven't cut this out yet, but it is a mostly done set of plans. It can likely fly on a power pack C, and with 9 gram servos. Some reinforcements (horizontal stabilizer and firewall) are recommended.
