Cermark F-16
I’ve heard these can go as fast around 150mph,
I flew it with an OS .60FP and it screamed.
people but the OS90fX in it with a tuned pipe and they go vertical outa sight.
mine has teh spinner but no engine, could even be converted to electric easily.
i also have a H9 jackal .50 that has atuned pipe. It’s flies like a bat outa hell.
i also have a .60 size PC-21 unbuilt ARF
