Removable Tail For Fun Cub
I love the removable tail on my FpVz Star and thought it would be a fun conversion for the Fun Cub.
Here is how I went about it.
Perhaps the most important thing to remember is NOT to glue the tail wheel mount "plug"/"insert" into the fuse tail. This can be pressure fitted just fine and if glued will render the removable tail useless as you will not be able to remove it.

Drill or melt or poke 1/4" hole through center of molded "Target" on horizontal Stab
12mm bushing inserted in horizontal stab. (Bottom view) Press fit tight.
horizontal stab (top view)
flush in bed is very important. Test fit vert, then glue
notch the tung on the Vert. stab. about 1.75"
notched tung (bot view)
1/4x 1/4 Birch/Maple "motor mount stick" will be the anchor plate.
channel the notch 1/8" or half the depth of anchor block.
For depth reference
inserted. flush and snug
carefully shape and contour block to match the foam tung's original shape. This is important for a nice fit.
insert vert into horiz and use a long bit through the bushing in the horiz to mark center on the mount stick. MARK ONLY.
don't drill yet! Just mark center.
now REMOVE the block from the fin and drill through it on a flat surface.
CA the hole to strengthen the wood. No kicker, but make sure it is dry before next step!
Tap hole with appropriate size hand Tap. Make sure glue from last step is dry first! Then re-glue new threads with CA and repeat tapping a second time. Run bolt through the new threads about ten times or so for perfect fit. Wax bolt if too tight.
glue block into slot making sure to keep flush on all surfaces. I used Med CA and kicker.
Install vert fin into horiz stabilizer and assure a snug straight fit in its saddle. Then thread wing bolt through horizontal stabilizer into vert fin's anchor block about 1/4 inch and lay the horizontal stab into its nest on the Right half of fuse side.
trace the bolt sides onto the right half of the fuse side. This should intersect the mold "target" on the fuse half as well.
notch, carve or melt, beds for the bushing guide. I had two pieces (I made a bad cut)... you could use just one long one. You could also make wood bushings instead of nylon.
they/it should lay 1/2 way deep in the bed(s)
test for alignment. The larger bushings should allow for some play with the bolt. notch the top and bottom of the fuse halves where the bolt will enter/exit. Repeat this bedding process for the Left fuse half. then glue them/it to one half of the fuse s
the finished fuse should look like this with the hole centered on the halves
Test the fit by dry assembling the fuse sides I made sure to countersink the bolt so the head sits flush. The bolt head should tighten up against the lower bushing, not foam. Once the fuse halves are completed (motor mounts, latch... etc. you can glue t
