OS .46 LA Challenge
Hey guys I thought this might be fun. Lets design an inexpensive, easy to build, speedy plane around this engine.
No particular reason but I bought one from a guy for $15 bones and I keep looking at it sitting on the workbench.
It was all gummed up and I have cleaned it up and it is a runner. This is an inexpensive engine and who knows it might help some other folks who want to try speed on for a change.
Here is what I am thinking (rough guidelines):
1. Should incorporate good slow speed handling (no nasty tip stall characteristics).
2. It should look as cool as possible!
3. Target top speed at 80-90 Mph.
4. Build should be easy and inexpensive, i.e. standard servos etc. (what do you guys think spad or no spad, I vote no spad).
5. Flight time around lets say 8-10 min.
Let me know if your up for the challenge!

RE: OS .46 LA Challenge
I remember a similar challenge a few years back. Essentially, it was who could design and build the fastest plane around a low cost, plain bearing 40, the OS LA or FP if I recall correctly. The rules were minimal. Your goal of 80-90 mph should be easy with an LA 46 (we are around 90 mph with our LA 15 powered club racers). Paul

If you like to build (since you want to do a scratch design), a Lanier Dominator 500 costs $60 direct. Build it light and clip a few inches off each wing (the 46LA is a light engine) and it will be plenty fast and entertaining. Cheap, simple and very easy. Not an original design, however...

I think that the general idea has merit, of using an cheap sport engine and seeing how much can be achieve. A stock quickie will do about 90 mph with just a .25 BB engine, while with a TT .40 120+ mph seems the norm with a stock engine. Clipping down a quickie's wings and a bit of clean up with the .46 should also run above 120.

Always fun to design something quick.
