Plane for a 3w24?
 

Any good flying, easy building planes for the 3w24?

The 3W 24 will pull around 11 to 11-1/2 lbs. very nicely. It will 3D, but will not be an animal by any means. The key is to fit it to the proper frame. The most popular combo for that engine was the original 3W 'Extra Fun' which built between 10-1/2 to 11-1/2 lbs. The secret to its success on that bird was that it sported 1320 sq. in. wing area. For that weight, it was a great combo.

A proper running 24 will yeild app. 7400 rpm spinning an 18/8. I forget the thrust #s.

The second edition Extra Fun was 1 lb. lighter with a 28i on the same wing area. Now that is an animal.

Back to your original question.

This is just me thinking out loud, I have not tried this. If you like bipes, I always thought it would do well on a GP Super Stearman, as that frame would carry the weight and sport around pretty good with the right prop. Can't tell you how the build is, but if a friend of mine gets off his duff and builds his, I will get back with it.

I'm sure there will be some very qualified suggestions to follow by others.

Good luck and let us know how you make out. Joe

In the scale or giant forum I would agree with the Stearman but here in the 3D area a Stearman bites. Check out OMP for a 65" Yak. I'd say your gonna get your best wingloading #s with a plane like this.

I found a Photo.

Man it looks like it'd be hard to fab up a mount on the Yak. Its on a 82 inch profile Cap 231 now, has a fiberglass mount molded in.

My thoughts exactly. The profile offers a good target weight and has the wing area for this power plant. Getting it on there will present a challange, but could be done with some creativity.

There is another aspect to consider. The 24, with the old style ignition needs some seperation between ign. and RX. Can this be done and still balance on a profile?

The newer 3W's with the more advanced ignition brings that seperation down to 4 inches and I have brought it closer than that without RF issues. Joe
