OMP 540 profile !! Love mine to death !

The kit is $60 plus shipping. Hovers supper easy and the 3D is insain. Knife edge is clean ( no mix needed ) and the water falls are tight. Put a satio 72 in it and you have a small plane that has the power to wieght ratio of a toc and will do any thing you can!

If you dont like profiles you can get somthing like the flip or the ucando. They dont have the p/w ratio but there still pretty high.
