Biplane Roll Rates - two ailerons vs four?
I have only had two biplanes. A DP ultimate and a 1/3 pitts. Both these bipes had ailerons on upper and lower wing.
I have a GP P-6E Hawk coming and now I am having second thoughts. GP's Super Stearman (same size as Hawk) has ailerons on both upper and lower wing. The Hawk only has upperwing ailerons. Now I am not going to 3D this plane. But it is going to have smoke and do big beautiful smoky basic aerobatics. but now I am wondering if this Hawk will have a terribly slow roll rate with only one set of ailerons. The real Hawk was a combat aircraft and only had upper wing ailerons.
So would anyone like to comment on this bipe roll rate issue - four ailerons versus two. thanks.

I have/had Ultimates, a Tecate, an ACE 4-60 and BUSA Phaeton 90 as well as other bipes needing completion. Yes it will roll slower than with 4 ailerons, but not so slow you would hate it. The top wing ailerons are probably larger than what they would be if it had 4 ailerons. My 4-60 and Phaeton (lower wing ailerons only) have adequate roll rates for the type of aircraft the are.

I have both the GP Super Stearman and the GP PT-17 Stearman which is the military trainer version of the Super Stearman. The PT-17 only has lower wing ailerons and yes there is a roll difference. All you will need to do is use more down elevator when inverted in the roll. The amount of rudder will stay the same

There is one other thing that may be a factor. the lower wing on the Hawk is substantially smaller than the upper. It also appears that the upper wing ailerons are farely good size. The Hawk was the last combat biplane and that smaller bottom wing may have been a transitional design development leading to the monowing.
Bubbagates, I pretty sure the Hawk is just another version of the Super Stearman designwize. Have you found the Super Stearman to be a solid design that can take some serious flying. Or is it a scale putt-around plane.

Exactly the setup (smoke & G26) I'm putting on the Hawk. I am having second thoughts because after I saw the Super Stearmen I just thought it was a lot more stricking, visually, than the Hawk and I like the quad ailerons. I may still send the hawk back and order the Stearman.

In my opinion, it rolls pretty fast, for a golden age era plane. But you would need to see for yourself. Fast for me may be slow for you.

sorry to be picky old boy but the gloster gladiator was the last combat biplane,the portugese air force used them until 1953!
