After putting 10 or 12 flights on my new U-Can-Do 3D .46 I've decided to replace the Super Tigre G.61 (2-stroke) with a Magnum XL-70RFS 4-Stroke. I've read good reviews about the engine and I've watched several UCD's fly at our club with 4-stroke engines and I feel that type engine is better suited to the flight characteristics of the airplane. From the specifications, it looks like the mount bolt spacing is the same, so I won't even have to re-drill or replace the engine mount (how conveeeeeeeeeeenient!). Another plus is that my trusty G.61 can go into the airplane it really belongs in; the Killer Chaos I'm currently building.
