3 or 4 engines

I was talking about my Nosen Trainer in another thread, and it got me tothinking again about building a plane with 3 or 4 engines. I had aTelemaster a few years back with a Saito 65, which could be removed andreplaced with an OS 20 FP. I built two engine nacelles that went on thewings to make it a triple 20 FP airplane, and the best part was that Icould switch back and forth in about 15 minutes. It flew very well andthe power from either configuration was about the same and was perfectfor the plane.My Nosen Trainer had a similar arrangement. It had a 91 Surpass in thenose, and a cover plate that would cover the hole in the cowl when theengine was removed. I built four nacelles with OS 26 four-strokes thatwere linked together with some very nifty throttle linkage. Thenacelles were balanced so that changing engines would not affect thecenter of gravity, and they had overlapping propellers that looked verycool. The sound of all four engines was incredible. I'd like to buildanother plane with a this engine configuration. Here are some photosthat I took back in the good old days when digital cameras took reallycrappy pictures: only problem is that either configuration was just too much enginefor that plane. I wanted a plane that was light and easy to handle, butthe Nosen Trainer was too much of that. With the four engines running,it would taxi at almost take-off speed, and it didn't want to land atall. I ended up selling it to keep from wrecking it.I've been thinking that I need to build another plane with four engines,preferably OS 26 four stroke because I still have all four of thoseengines. I want something with a bit more drag. I was thinking aboutscaling up a set of Great Planes Big Stik 60 plans because of its thicksymmetrical airfol. Any other ideas? I'm almost finished with a LazyAce, and now I'm thinking that it would have been perfect for four OS26s, but that probably would look funny and it would be way too muchbuilding for one plane. It...

That's funny. I was reminiscing about the sound of four OS 26 Surpasses on my old Nosen Trainer, and I ended up deciding to put three 2-strokes on something. What I really need is multiple OS 26es. The Cloud Dancer would sound nice with two of them.
