First attempts
The first model I seriously tried to hover with, was a hybrid with the wing from a Super-Pacer, and a home made box-fuselage. The power was an old Webra 32 equipped with a Bolly 4-stroke muffler. This model had too small control surfaces, and hovering was difficult, event though the power was sufficient.
My
first non F3A model with more than 1:1 power to weight ratio.
