I have 2 of these, one with a Saito .72 and the other with a .46FX. The 2 stroke is by far the easier plane to hover IMO. The 4 stroke has power galore but I seem to have to "work" the plane to maintain a hover.

Be sure to do ALL of the following:
1. Balance the plane 2" behind the main spar

2. Balance the plane laterally, supported by the fuse at the front and the tailwheel at the rear. DO NOT use the engine crankshaft to support the front as the engine is offset from center on these profiles and will result in an imbalance that will destroy the 3D characteristics of this plane.

3. Dail in 2-3 degrees of right thrust. I have 2 number 6 washers between the fuse and the engine on the front engine mount screws (6-32).

4. Max rudder throw and elevator throws with lots of expo, mine is set to -50 on both and seems about right (to me anyway), adjust to suit your individual needs as you progress.

5. If you don't have a PC sim to practice on then you are going to be burning A LOT of fuel and fixing the plane periodically. Hovering is NOT easy at first and anyone trying it on a sim will find themselves crashing a LOT before they finally "get it".
