Have engine, muffler mods made, it runs great, many actual users of this engine have said this engine runsfine, quiet, pulls up to 13" props , not!!! junk. Gotta fly off paving, not aware of any grass IC fields in So CA area. ( I fly at El Toro MCAS).
I am not a beginner, this size and type of model are new to me.
(see my avatar Gee Bee E). I have been flying an electric converted Guillows 28" PT17 which is probably trickier than the big Camel to get and keep flying. Just looking for any specific advice on the VK Camel
