A P70 fits in the old 5" ducted fan airframes easier than a dynamax does. There are a lot of those old engines out there that are still good and can be had inexpensively. The AMT Mercury even fit pretty easy into those old DF airframes. I can't justify the cost of the kolibri's or P20's etc for what they are. I love my big engines, but I love that my P70 is inexpensive to run too.
