Hi Chopper Man

I feel quite relieved that you have decided aginst the four stroke for that airplane and I quite agree with most all who felt that the listed engine would be a dog on that airplane and it certainly would fly but never be able to perform to its best. Every airplane has its mission and no particular engine type fits all.

This airplane is definitely best suited with a good two stroke as was intended, Remember This airplane is a descendant of a long line of Kaos' that were intended for old AMA pattern type aerobatics which was flown at fairly high speeds and is a completely diffierent type of flight from what is normally called 3D Actually those airplanes a by comparison are quite slow.

As to the Magnum .46 While not my favorite engines (for reasons that has nothing to do with just power) can work for you. Yes I have used many of the .25 sized Magnums of the same model as well as several of the .46's in the past. What you will find with the cheapie engines is consistency some may be great and some less so. This factor is perhaps not quite as bad with the magnums as some others.

I also would like to say I completely agree with Jaka in the choice of using a Dave Brown mount in place of the clamp types also what jaka is suggesting is just plugging your existing holes with sticks (after popping the blind nuts out) and dripping CA then cutting off flush. This is a very common method when relocating engine mounts and it works well. I just mentioned it in a different manner to make it more understandable, Hm hope I succeeded

Also Jaka proposed another trick I have not tried but sounds like a wonderful technique that I certainly am going to perhaps give it a try some time. I believe what it entailed was actually just sticking the mount in position and using a bit of CA to hold it for drilling actually using the mount for a drill guide[8D]

Now I have always been in the habit of mounting the engine first to the mount then positioning the engine and mount assembly in position making things pretty simple to position the engine with the mount so what I normally do is use a wonderful little tool called the Great planes Hole locator:

About eight bucks and to me almost indespensable . With this tool its easy to position the engine mount assembly where you want it and mark the hole then just sit the engine aside and drill the holes. This tool is just as useful in marking the beam holes for the engine mount and makes it a breeze, I would bet the trouble and fear the fellows have in drilling them pesky beam holes is why those clamp mounts are still around.
