I’d like to see more challenging designs that use Power Pack ‘B’ or smaller, swappable engine & electronic pods, with wings cut from a single FT Foam Board or DTFB (wingtip to wingtip) fitting at the biggest within the board diagonal, same for the fuselage. Larger than micro, but including some master builder techniques with up to 6 channel options like ailerons, flaps, flaperons, spoilers, multi-engine, fixed gear or retracts option, etc. Call these, advanced mid-size designs. Some builders might like the master series designs but lack the bench or shop size to build those.
