I am building an LT-25 and will need to make a decision on the engine pretty quick. I know the recommended engine size is around a .25 2 stroke. I have a NIB Magnum XL that would work and also have a NIB O.S. FP40 that weighs the same as the magnum. I am betting the Magnum will put out the same power as the FP. I am a real fan of plain bearing motors and am considering the FP over the Magnum. I have owned 3 Senioritas all powered with FP-25s and they flew fine. I think the Seniorita is just a little lighter in weight.

I will most likely pull the radio on my Aircruiser and it has an FP-25 on it that could also be used. So what do you folks suggest?

I do remember one poster stating he had an LT-25 with an FP-40 on it and said it was the funnest airplane he ever had. So thats why I am considering the same engine.
