Mini Talon Collapsible Launch Hook
I wanted a collapsible launch hook for the Mini Talon because there are days without wind where I would rather use my bungee than risk a hand launch. This piece then glues on/into the fuse right up against the front wheel hump. It is additionally secured by two prongs of plastic which are buried in the hump foam.
As in my other Collapsible Bungee Tow Hook, it uses an aluminum tube for the hook part with a 3mm pivot bolt. For glue I use either white tube glue or Beacons FoamTac.
Only four simple parts. The hook piece is made from 5/16" (8mm) aluminum tubing 35mm long with a cross drill 3mm hole at 5/16" from one end. The bolt is a 20mm M3 screw cut down to fit and the nut is a Nyloc hex nut.
To install the hook assembly, hotwire two holes in the back of the "hump" to receive the two plastic tabs and cut a small amount of clearance for the tube. Cover all surfaces with your favorite EPO glue (NOT Gorilla glue) and press into place. Hold with a clamp or stretch some tape over until the glue is fully cured. Assemble all parts as shown.

After releasing this idea I got some feedback from an RCG poster who requested I tweak the angle a little so that the bungee ring won't slip off. I made this change adding ~10 degrees to the angle and additionally created a printable "tip" which should help even more with ring slippage. Here is a picture showing the differences:

- 1x M3 x 20mm SHCS (Trim to fit)
- 1x Aluminum tube, 5/16"OD x 1/16" x 1-3/8"L (8mm x 1.5mm x 35mm)
- 1x Tube_End.STL - Optional
