Quest Striker AGM Build Part 2 Engine Mount Adapter

Step 1 is a typical engine hook install.
Slit the tube 1/4" from one end. Insert the hook and wrap with tape in the middle.
I substituted a 2 3/4" length of BT-20 for the thin Quest yellow tube.

Check the first photo. The interior ribs extend past the top and bottom of the adapter a little bit. Sand the top and bottom flat so you'll have a better flat gluing surface for the centering rings.



After the rings were glued in place, the adapter assembly wouldn't slide into the 35mm tube easily. Sand the ring edges to the diameter of the upper and lower adapter ends.




The smaller, lower ring will be exposed.
The brown ring is a little rough. I hardened and sealed it for smooth sanding by applying a coat of CA brushed on with a Q-Tip. A little sanding with 400 grit will leave a smooth surface for paint later on.

There is an "gotcha" in step 3. With a wrap of tape around the engine tube and over the hook, the tube won't slide into or past the upper centering ring.
I removed some tape and widened the inside ring diameters for a better fit.
I'd recommend cutting a notch for the hook, especially on the lower ring. Otherwise, there wouldn't be enough hook movement to allow an engine to be inserted.
