Stirring the crap eh? The Curare is designed for a 2 stroke, old school speed-pattern... Find the fastest airplanes in the 40-50 size and see what engine is up front--- you started the thread with a request for a 46 sized airplane, remember?

The Curare is not gonna compete with a Diamond Dust no matter what you put up front- The quickee is the best combination of speed and ease of operation--

Dude, here it is... Sell the OS-46FX, put the cash towards a Jett-50, get a quickee- pin the firewall and light your hair on-fire!
