Coro-Cub - giant scale SPAD J3 Cub
Giant scale SPAD J3 Piper Cub (86 inch wingspan) flying at Mather Aerospace Modelers field. This was a maiden flight for that plane as well as for weed-whacker engine Poulan 25cc converted to RC gasoline engine with glow plug ignition. The cool thing is, that the engine runs on gasoline, but uses glow plug ignition. Coro-Cub was built on 25% scaled up plans from SPAD website. The plane came up at about 15lb and with wing area of 1300sq inches makes reasonable wing loading at 26lb/sq ft. The plane performed quite well and the engine proved to be quite reliable too.
