Hi Steve!
The eindecker is a great kit and nice flying machine. There are only a few changes, we did:
Change the steering for the wing-warping to a scale version. I highly recommend to use a lare servo, because there are big loads on the warping, but it does nice rolls (for what you would expect from a EIII

)
Take some time to think about the rigging of the wing, to make it easy and reliable.
Ours flew very nice with a 7 cyl Seidel radial.
Best regards,
David
