RE: sopwith camel
 
A friend brought out a very nice Balsa USA Sopwith Pup last week -really a super job
So I reluctantly asked him "where is the spreader bar on the landing gear.
he said "what is that?"
I noted that all the WW1 stuf I knew of, had a spreader bar or plate on the gear.
He said he had seen nothing about that in the kit . I was puzzled. A while later he walked over with the scale photos -and it had the spreader bar. He was puzzled - "nothing about it in the kit" he said - so we had a BS session about why the spreader bar and what about the tiny tiny vertical fin and how do you take off n land these types .
They are a in a class all by themselves .
Instant ground loop on take off or landing is easy to come by.
My scale Bucker Youngmann at 30% size and 17 lbs will take off and can be landed - blindfolded.
Not so these old WW1 types.
As for toe out toe in different AOA to or bottom panes
I go for 0-0-0-0- then try to land on the mains and then back of power
Once the thing is at the sitting angle, control is all but impossible unless you have a solidly steerable tail wheel.

Don't know if it's an optical illusion, or...(? ) but the lower left wing looks like it has a little more positive incidence than the right.
Do you have an incidence meter?
