I have the Eindecker you are building. Great little fun flyer. What engine are you using? I have a Magnum 52 4 stroke mounted inverted and it runs great. no problem starting, holds a good needle setting. plenty of power for plane. I built mine scale with the scale landing gear and tailskid. Ground handling leaves something to be desired, so if you don't care about scale looks, might consider a tailwheel. I painted the cowl with Krylon Fusion aluminum paint. It looks just like real aluminum, very impressed with finish. I don't have any of the tip stall charateristics that is mentioned in previous posts. as with any taildragger, once you start your takeoff run, ease off of the elevator, let the tail fly and she will takeoff when ready to fly. Climb outs with the magnum are good, and engine has more than enough power to fly the plane through basic barnstormer aerobatics.

Good luck and have fun
