Brief:
This is a motor mount t' accommodate a 29mm motor in a BT-60 body tube. Ahoy! It is 5 1/4" long.

Construction:
T' package consists o' simple instructions, shiver me timbers, 2 centerin' rings, a thrust rin' and a motor tube. Begad! Blimey! Well, me hearties, blow me down! Blimey! Construction o' the motor mount was simplicity itself.

T' motor tube be marked 1/4" from one end. Avast! Avast, me proud beauty! T' two centerin' rings were then test fit around t' tube. Begad! One fit just fine and t' other needed a good bit o' sandin' t' fit around t' motor tube. Aye aye! Begad! Once they fit, shiver me timbers, I placed one even with t' 1/4" mark and t' other flush at t' end. Ahoy! T' rings were then epoxied in place with 5 minute epoxy. Well, blow me down! Begad! A thrust rin' was provided and epoxied into t' end with t' flush centerin' ring. Well, matey, blow me down! When t' epoxy on one side be set, I turned it over and painted it on t' other, buildin' up a good fillet on t' aft rin' and sealin' together t' thrust ring, matey, me hearties, motor tube, shiver me timbers, and centerin' rin' on t' forward end. After that, it was just a matter o' waitin' for t' epoxy to cure.

Flight:
T' mount be tested on two different flights. Ahoy! It handled a Roadrunner F60 and an Aerotech G77. Ahoy! I had planned t' use a Roadrunner G80 for t' second flight but could nay because it would nay fit. Well, blow me down! T' Roadrunners have a built in thrust rin' aft but, forward o' that, are o' uniform diameter. Arrr! T' AT SU motors do nay have a thrust rin' aft. Avast! Ya scallywag! They are also necked down t' a smaller diameter where t' ejection charge is stored. Blimey! This allows t' "skinny" part t' slip through t' hole in t' motor mount's forward thrust ring.

As long as this fact is taken into consideration at design time, I can heartily recommend t' mount.
