Default OS 61fx in pulse 40

Is this overkill in this plane? I went with the 55ax but can still return it and get the 61. What would you fellas suggest? Also with a large engine in this plane would it cause structural damage in a full speed dive? I was going to go with a pitts for the 61 if I change from the 55. Thank you all.

I would rather have the 55 than the 61. The 61 is heavier and an older style with not much more power than the 55.

Remember, bigger isn't always better.

The 55 is more power than you will ever need in a PulseXT. A 61 is just overkill in both power and weight.

Everybody above has given good advice. Go with the 55. The 61 is going to add a lot of extra weight, the engine and the weight needed to balance the plane, that will put a lot of stress on the airframe. In cases like this a "full speed dive" could well result in the plane coming home in a trash bag.
