bipeplane or monoplane for indoor patern?

what do you think is better and why?

Biplane seems to fly slower (greatly depends on which one) but also is softer on some things such as snap. Downlines are slower depending once again.

Monoplane seems to do rotational figures better. Downlines are faster.

My .02 and mileage varies a lot. :D

I think one reason for the success of monoplanes in full-size and F3A model aerobatics is that they are easier to judge. Apparently the outline of a bipe gets so fuzzy that the judges have problems seeing if the plane is tracking correctly.

I wonder if this is an issue in indoor flying.

One nice thing about small planes is that experimenting does not cost much and build times are short. Get some plans and depron. Build a plane. Next, build a slightly different one. Which do you like better? Now build another different one, ... Build a seriously different one just for fun.

I recently saw an interesting one on rcmania.cz (the site seems to be suspended right now): a shocky type fuselage, triplane with a big wing in the middle and very narrow chord wings at the fuselage top and bottom. Only the big wing had ailerons. I have no idea, how it flies, but it looked cool:)

Another interesting biplane to look at is the Sypher by Insane Foamies. I've seen it fly and it will do some very interesting things. The great thing about indoor is it's so easy to experiment , almost anything will fly.


The little bit of full scale competiton that I've watched was exclusively monoplane in the more diffiicult classes and biplane in lower classes.

The biplane offers more wing area for a given 3d space and can result in a much stiffer airframe overall. It also has more inherent drag than a monoplane which all results in an airplane that is able to maintain a slower speed more easily. The downside is a biplane can be very difficult to trim properly.

biplane weing in my book.

Flys slower, and looks better. and is tuffer
