Here is that guy hovering the heck out of one with an O.S. 91FX 2 sroke.... O.S. 95AX should be plenty! I have not seen a comparison of a 91FX vs 95AXbut they shoud be close in power.
With the engine already up pretty high in rpm, you can see and hear when he needs a little boost and the engine responds very quickly.

The $ is about the same for the 95ax VS DLE20 but the 95AX is 3 oz lighter with muffler (84g). That's a lot of weight in this plane, I think.
On the other hand, you will probably pay much less in fuel-per-flight for gas vs glow fuel.
Gasoline is cheaper per gallon, AND provides more power per gallon.
