Greetings from Canada,

antique opa, Thanks for posting the specs for the Dave Johnson Fokker D-7. Those are what we used starting building coro WW1 combat planes 4-5 yrs ago.

Around 44in. span with 500sq.in. area and a 1in. thick flat bottom airfoil works great with 4-5lb weights. Many time repaired ones are still flying around 6lbs, but are more like Recc/bomber performance.

We prefer the O.S.FX with the baffle in and/or a muffler tube extension. (it makes cleaning them so much easier with a 4in. muffler extenson)
10-3 10-4 11-3 props

We just scale up any WW1 subject we like and 'adjust' the outline to make it look like a good flying model airplane. i.e. lengthen the nose/increase tail areas/put the wheels in the right spot/simplify cabanes/etc.
They all look cool from 15ft in the pits, and even better 4-6 planes up in a Heat !!!

They are great flying sport planes.

We started building a few WW1s to use up old O.S.FPs/Magnums/etc that could not compete with the O.S.FX for our WW2 combat planes. None of us ever thought WW1 combat would be so much Fun! Or that we would get 10-15 pilots flying in a WW1 Match !

All it should take in your area is to build two, tie some streamers on them and the interest will grow...

I hope you get a chance to fly WW1 combat. We have a laugh every time we fly them...
The spectators really like it too...

Take care,
Have fun,
