Nah, I like the C.G. right where it is at... if anything a bit MORE rearward would be good to me.

Idle speed is fine too. I'm running an 18x8 or an 18x6 prop on any given day... This on a 74" plane.

My Yak has pretty thick wings, giving it a lot of slow speed lift ( just like my Funtana, and U-Can-Do ), so all of the planes exhibit exactly the same behaviour.
