Hey Ed, Nice work. But Baaad timing! It really sucks having a finnished model sitting around for 3 or 4 months waiting for a maiden flight. Were did you get the prop boss?
I used one of those props for a while but after an rpm check I discovered I was losing about 800 rpms because of the difference in the weight from a Zinger. 18x6 is what Zenoa recomends but I ended up using a 18x6-10 and I am very pleased with the performance.
I wasn't happy with the taxiing characteristics with the stock tailskid and I put a brass plate on the tip. Now I can taxi up and down the runway and hardly ever have to go chasing after it to retrive it from the tall grass. For looks a nail or rod inserted into the end of the tailskid would probably also do just as well. Good luck with you eindecker.

Cam, do you have any pics of your build? I'm working on wire wheels for my eindecker. If they come out ok I will redo it as "509". You should have yours up for a few months by the time the snow melts around here Going skiing Thursday. That should take my mind off itfor a while
