Irish: I had a Ripmax Rapier once. Very similar to the one you showed. Mine had a v-type vertical stab was the only real difference. I had an OS 50 on board and it did scream. We clocked it at 121 mph with a police radar. And, with the 'proper' prop, it would go even faster.

It was not a handful once I properly set up the aileron and elevator functions (separately for the Elevon setup) and removed some of the throw, (on maiden, it would corkscrew aileron rolls to the tune of about 2 per second.. jeech). My instructor flew it first, he landed it, then I toned it down a bit, he flew it again, and it was fine. So, I put it up. What a blast!!

One thing you have to keep in mind with this airframe is if yours does NOT have landing gear, you have to shut the engine down on final and land it dead-stick. So, you have to be sure of your landing, confident it's doing what you want it to do, then cut the throttle. The prop has to be set up properly too.. with the prop on parallel with the wings (on the same plane) so that the engine is just beginning the compression stroke as the prop is parallel. That way, when you shut down, the prop stops and won't hit the ground.

Mine had skids on the bottom that had a layer of ply to take the scraping on the ground when landing.

It was a lot of fun to fly, for sure. Looked pretty neat too.

I was in England a few years ago working most of the summer over there and went to an big.. and I mean huge.. RC airshow called The North Weald Wings and Wheels Extravaganza. The manufacturer of that particular aircraft had several of them, all set up and different colors. They were all on different frequencies so they flew 12 of them at the same time as a demo. Pretty slick!!! They were doing this huge formation flying demo. And, yes, there were some mid-airs. Left the ground with 12, landed safely 8 of them. They didn't care... manufacturer flying the things. The attached picture only shows half of the ones that flew that day.

You ought to consider keeping it and flying it. You will have lots of fun with it.
