I was thinking of trying to use this on a Lanier Laser 200 1/4. I plan on making alot of mods to make the plane light as possible. I'm hoping to get it at 8 lbs or less!!! Has anyone converted this engine, and if so what did it end up weighing, prop size, RPM??? If anyone has any other suggestions for this plane, please feel free to input. I would like to be able to hover. Thanks for the help.

The 25 weighs about the same as the 18 (3 lb with flywheel) and has almost 40% more displacement. Do a search on featherlite and ports to read about some of the limitations of this engine.

Here is a link to my port photo:
