First photo shows my F6 waiting for mains to arrrive. Also shows scale tailwheel location.
2nd photo shows closeup of tailwheel installation. Very straightforward. Glued in a platform of light ply with balsa reinforcing (unseen in photo) above. A better view of the retract mechanism can be found here http://www.robart.com/retracts/tailmech.aspx
3rd photo shows homemade switch to turn of tailwheel steering when retracted.

I think the tailwheel model 122 I used here is way too lightweight for this size model. I'll be looking for an upgrade. Still, in a hobby that's all about things "I like".. I like it! LOL

Took a photo of the pilot too. Too blurry to post. Inexpesive and perfect size from Hobby Lobby International. See "Garry" here http://www.hobby-lobby.com/pilots.htm for $6.20
