A 4 stroker in a Kaos? Anybody else agree with me that this borders
on blasphemy? Its like putting ketchup on hot dogs. There are some
things that are simply not done.

Seriously though...I have a 40 size Super Kaos built from an
original Joe Bridi kit and power it with a TT46 Pro with Tower
tuned muffler. It literally rips. The TT46 just BARELY fits in this
plane, A larger motor would require major modification.

Another pilot in our club has the Tower Kaos 40 ARF and powers
his with an OS 46 AX. Its nearly as fast as mine despite being
a slightly larger airframe. The Tower ARF has more room in it
for a larger motor but the fit is still a bit tight.

These planes are perfect with a strong 46 and fly the
way they were meant to. I dont see any advantage
to a 4 stroke in this plane.
