Good catch on the bearing...I will make a revision and then post the
plan to this site and update the one over there. Working with my
daughter last year and bugging Jeff Anderson with lots of questions,
and now Parker this year has us all hooked on indoor. We are
currently building a covey of Kagan Eidolons. We hope to meet some of
you this summer. We live in Michigan and think we can get to
Lakehurst, Akron, and hopefully one other. We fly in a church gym
with a smooth ceiling with recessed can lights. A great low site.

bearing that would let you remove the prop or use interchangeable
props? You can either make a wire bearing that would allow you to do
this or use a Harlan Pennyplane bearing. If you use the Harlan
bearing you may have to drill out the holes depending on what size
prop shaft you use. I use an .020 prop shaft and drill the bearing
with an .022 drill. If necessary you can strengthen the front of the
bearing by gluing in a tiny wedge of balsa.
