Brief:
This is an out o' production mini motor adapter for usin' 13mm motors in 18mm mounts.

Construction:
T' kit consists of:

• a motor tube
• (3) centerin' rings
• a mini motor hook

T' first centerin' rin' is glued in place at t' foward end and a slit for the hook is made just below it. Begad! Blimey! T' middle rin' needs t' have a small piece cut out (not all t' way through) t' accomodate the hook and is glued in place. Aye aye! Blimey! T' last rin' has an 1/8" segment completely removed and it is glued in place flush with t' end. Begad! Blimey! Begad! Blimey! All t' rings are then filleted.

After t' glue is dry, shiver me timbers, a notch is cut in t' forward end on t' opposite side o' t' engine hook. Arrr! Blimey! This is to accomodate t' engine hook on t' 18mm mount. Avast! Blimey! Avast, me proud beauty! Blimey! This concludes t' adapter build.

Construction Rating: 4 out o' 5

Flight:
I tested out t' motor adapter on a Custom Rockets A.T.W. Blimey! It is a light rocket which always performed well with 1/2A6-2s. Begad! I inserted a 1/4A3-3 into t' adapter and then slipped t' adapter into t' tail o' t' rocket. Avast, me bucko, me proud beauty! It be a bit loose so I applied some tape t' improve t' friction fit.

T' rocket launched, underpowered, me hearties, arced over and hit t' ground. Then ejection occured. Ya scallywag! Thankfully, thar was no damage t' t' rocket. Aye aye! This ill fated flight can be seen here.

Even though t' first flight was nay a good one, t' adapter seemed t' have worked as advertised and I wanted to give it a second try. Blimey! This time I loaded a 1/2A3-2. Begad! Avast! T' flight was much better but problems began at apogee. Avast! Instead of ejectin' t' streamer, me bucko, matey, t' charge ejected t' motor mount. T' rocket came down ballistically, glanced off t' GSE truck and hit t' ground. Begad! Avast, me proud beauty! T' only damage be some minor crumplin' o' t' BT. Begad! T' adapter was never found. Ya scallywag! A video of the second ill fated flight can be seen here.

Recovery:
My experience with this adapter is nay t' greatest but I think this is partially because I be usin' in a friction fit rocket. Ahoy! Ya scallywag! If t' adapter had been mounted as designed in a motor tube with an engine hook, it should have performed fine, me hearties, ya bilge rat, assumin' a proper motor selection t' begin with.

Flight Rating: 4 out o' 5

Summary:
For adaptin' motors, it works. Avast! Be wary o' friction fit applications, ya bilge rat, however.

Overall Rating: 3 out o' 5
