This is my first AV. This is of the default Yak 54. It has been reduced in size to close to .60 size dimensions, and uses an O.S. .61 FX engine and a 12x8 prop. Please rate and give constructive comments (i.e. CG is off, move it x" forward, use a "Y" x "Z" prop, etc...). I will make the changes and repost.
