Estes Skydart II #3229 Build, Part 16, Rear Ring and Hold Down

I misplaced the split rear centering ring. I had to cut one from a spare 20/50 ring. (And of course, right after I glued on the replacement ring I found the green split rings from the kit.)

TIP: If you ever have to cut a notch out of a centering ring for engine hook movement -
Don't cut near the wrap seams, marked here with pencil. If you cut close to or on the wrap seams (either inside or outside) you have a greater chance the ring will de-laminate.

It took a few tries to get the ring in the right location. You want the back of the ring to be flush with the BT-50 body tube.

Mark with a pencil, remove the pop pod and glue the ring in place.

After the ring dries, slide the pod back into the main body.
Tape the elevator in place.
Set the elevator hold-down piece in place and trace around its location.
Scrap off any paint for a better glue bond.

Mentioned in an earlier post:
Don't sand down the curved bottom. I sanded the burnt wood off and the hold down piece ended up being too short.

The bottom was build up using two layers of 110 lb. card stock.


  1. I've always believed the quickest way to find something lost is to replace it. Normally within an hour or so of replacing an item the old one can be found.

    This is backed up by Murphy's Law, "Whenever you set out to do something, something else must be done first".

      I couldn't have said it better myself!
