Default My OS .40FP needs a home

As the subject says I have an OS 40FP just begging for a new home. I was wondering what the great minds around here would recommend for a plane that this engine would provide enough power for.

I'm open to anything...but I don't want a SPAD. I like the look of a real plane.

A Sig 4 Star 40 is a perfect match for the engine. Good Luck, Dave

Stick it on a Tribute 36 ARF. I had a TT42 on mine and it was awesome! My plane came in at 3lbs 14 onces ready to fly.

The 40 FP used to be known as the best 25 ever made. Torquey, easy on fuel and as reliable as a stone.

Pick the 25-30 size airplane you like the best, put the 40 FP in it, you will have a ball.

Lol...

That would then make the .46 FP the best .32 ever made?

I though that the "best .32 ever made" was reserved for the O.S. .46 LA.

There never was a 46FP. That's why the 46LA has that honor.

Do you really think the anemic 40FP is enough for a 3D plane like the tribute?

It won't have a ton of pull out, but I was able to hover well at 3/4 throttle with an 11x3. Excellent for fun flying and decent for basic 3D flying.

I'm building an old SIG Clipped wing cub to put my .40 FP on. Its rated for a 15 to 35 engine so the FP should work great. This plane is very agile and it can test your flying skills. You might consider it. I haven't look to see what the current kit is like the one I'm building has been laying around since the late 70s and I bought it off the guy that bought it orginally.

The 40 FP is the best 25 ever made? The 40 FP, while not a power house will fly most any 40 size aircraft. I have the 40 FP on my Sky Tiger, 4 Star 40, as well as 2 40 size ugly sticks. I would be the first to admit that the 40 FP was not designed for 3D type planes, however I can do what I want to with my planes including a hover of sort's. In my vested opioion these engines are one of the best made by OS. Good Luck, Dave

The 40 FP makes just a little more power than the 25FX. About the same as a good 28. But it turns a bigger prop, slower (less noise and longer engine life) uses less fuel and is far more reliable. THAT is why the 40FP was known as the best 25 ever made. And it's definately among the best engines OS ever made. Too bad the LA series didn't follow in it's footsteps.
