Building a DCU Mig-15. 50" wingspan, AUW is about 9-10lbs. Just picked up a BVM .81 engine and Viojett fan. Mig was suppossed to be powered by a Turbax I and K&B 7.5 engine. Was going to put turbine in Mig but would like to use BVM setup before I get coin to purchase turbine. Mig plans show blow in door but I did not cut out because of turbine setup. I have a BVM Aggressor II kit that does not have a blow in or cheater holes. Inlets on Aggressor are not much bigger than Mig. Question is will the Mig perform well with BVM engine/fan setup without the blow in door or cheater holes?
