If you haven't already purchased them, I'm curious why you chose the GMS .32 . I realize it's right in the middle of the range for recommended engines, but the GMS .40 is the exact same price. I think it is pretty typical that .40 size engines are cheaper than .32 size engines, simply because they sell more of them. There shouldn't be a big difference in either weight or fuel consumption, and a little extra power never hurts. Plus, there will be more airframes that you can transfer a .40 size engine to than a .32.

Good luck with your Kadet. It's a great choice.




****Edit - I stand corrected. According to the specs, the GMS .40 weighs 6 ounces more than the .32, that is significant. And if you can believe their HP numbers, even for comparison, they put out almost the same hp.
