Not really true... The Kitfox is ALWAYS fun to fly. The Titan was certainly heavier and that extra weight is noticed. The Radial was heavier as well..
But I would fly either to Oshkosh and back.. oh wait.. I did.😜
While I personally prefer the Rotax.. it is not for everyone. The Titan or the Radial are good choices.
The 3600 is currently being installed in 2 Kitfox's
