Brief:
This is a motor mount t' accommodate a 29mm motor in a BT-60 body tube. Ya scallywag! Avast, shiver me timbers, me proud beauty! It is 5 1/4" long.

Construction:
T' package consists o' simple instructions, 2 centerin' rings, ya bilge rat, arrr, a thrust rin' and a motor tube. Ya scallywag! Construction o' the motor mount was simplicity itself.

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

Flight:
T' mount be tested on two different flights. Well, blow me down! Blimey! Ya scallywag! Blimey! It handled a Roadrunner F60 and an Aerotech G77. Begad! Blimey! I had planned t' use a Roadrunner G80 for t' second flight but could nay because it would nay fit. T' Roadrunners have a built in thrust rin' aft but, shiver me timbers, forward o' that, are o' uniform diameter. T' AT SU motors do nay have a thrust rin' aft. Avast! Blimey! They are also necked down t' a smaller diameter where t' ejection charge is stored. Aye aye! 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, me hearties, I can heartily recommend t' mount.
