Gubbs3 is right. The SP-Sport 40 is a slow flying plane the will fly great with the engine you plan to use, but no chance whatsoever of it hovering with that power.
Landings are easy, but the plane often comes out quite tail heavy. I use a 4-stroke because they tend to be a bit heavier for their displacement.
I found a Magnum 52 4-stroke to be a good choice, and no added lead (weight) was required.
I also fly it as a float plane, and it's a blast.
