I am picking one of these up in a couple days and need engine advice..

I have the following Engines I can use.
An OS .46 LA. Really this engine is way under powered for it's class. I prefer to use it on a .30 sized plane.

MDS .48 I have not run this yet and I know MDS's reputation so I am a bit hesitant to use it.


Now my thoughts really were to pick up either an OS .46 FX or one of the New Evolution Engines from Horizon.

I know the OS is considered the standard but I have heard good things about the Evolution engine as long as you take the Flywheel off and get rid of the 3 bladed prop. It is also considerably less..

Now the Displacement and RPMs on both of those is the same however I have been unable to find the HP of the Evolution.

Normally I prefer 4 strokes. But Cost considerations is keeping me in the 2 stroke field for this plane.
However if I come into any money I would probqably put either a Saito 56 or 72 on it.
