I see there are a bunch of foamy bi-planes coming out. What are the pros and cons of biplanes over single wing foamys? I wanna get one asap and want to make an informed decision. THX

I personally think biplanes in general are making a comeback. They are not the sluggesh,nonperformance airplanes they use to be. I am building a fancy foam ultimate, my sons building a Raptor biplane and my brothers building a E flight ultimate. I personally think biplanes look better doing the manuvers. They are definately stronger just because of 2 wings and all the struts and things.

Do the foamy bi-planes fly as easy as the single wing foamy? Are they as nimble also? Thanks Capt,n

yes on all accounts. I don't beleave there is anything the biplane will do the single wing can't and vise versa.

I'm a huge biplane fan. I have many ultimates. I think the biplanes are much more stable in the air than monowing designs. Also with a shorter tail, it seems as if they can pull much tighter loops. The knife-edge is also far superior to monowing designs in my opinion. The cabane's act like wings during knife-edge flight resulting in tail up knife-edge instead of tail-down dragging knife-edge like the monowing designs.

Plus, seeing a biplane roll, looks much cooler than monowing designs. There is just something about seeing those two wings rotating in sync.

You guys still didn't point out if there are any advantages to flying bipes...especially in the foam ones.

I did point 1 good thing out, they are stronger. I beleave you have more roll authority just because of the 4 large ailerons. other than that I think is just really preferance.

there are a few other things that bipes have on monos....first they are less effected by the wind in a hover because one wing blocks the other from it....less span and generally smaller in comparison to the wing area(more compact)....you can use a shorter landing gear rod(lighter and stronger)....and your ailerons don't divert your thrust away from your tail surfaces in a roll....as far as I know the only down fall is the 5 minutes of extra time that it takes to hinge those 2 extra ailerons....

I have the tiger moth 400 with himax 4200-25 3cell lipo gerbox 6:1 11:80 prop and it is a blast!!!
It has a moderate sink rate but it handles the wind 20-25 fine. does not buffet like the slow stickor some others.
It has no tendancy to tip stall as of yet. I have put in a full length carbon rod in the wings to support the
extra forces I put on it with the himax motor, as when going full stick and doing a 180 tends to bow the wings.
I have made a biplane out of sheet foam and it flys great also.
They seem to handle the wind better, so I get more time in when I can.

hello,
I have the gws Pt-17. It has only 2 ailerons, so does not roll fast. It is very scale like with the stock motor. I found it to be very stable and a good aerobatic trainer. With my model motors mini ac, 3 cell 2100 thunder power, 3.8:1 planetary gearbox, and a 10 x 4.7 apc, the stearman becomes a rocket with 2 wings! At close to 2 to 1 power to weight, it is not surprising you can climb out of any trouble.

The down side of biplanes is the extra drag the second wing creates. I have found it is not as good in the wind. You should never fly in wind with stock motor. If you do have a brushless setup, you can try to fly in the wind. It just does not like to penatrate. Biplanes are slow compared to monoplanes. When compared to a flying wing monoplanes and biplanes suck in the wind....get a flying wing for windy days
