RE: U-Can-Do 3d 46?
Spend the extra money and get the 70 Surpass. You may be able to barely hover on the 52, but you won't be able to do it low enough to fall out of the hover. With OS 70 4 Stroke you can hover as low as you want and pull straight out of it.
Since you are basically buying a hover machine, power it enough to pull straight out.
