Interesting pair of cars. Never had the pleasure of a Rytecraft. Bit of a sad tale of Friskys. Still at least you have one.
Bumped into Alan Hillier, who campaigned a yellow F3 for a few years, taking it on some stiff road runs. Something of the standard barer at the time. He still remains interested despite not owning a Micro now. Bit more endeavor with Friskys now, it seems.
