Brief:
This is a motor mount t' accommodate a 29mm motor in a BT-60 body tube. 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. Construction o' the motor mount be simplicity itself.

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

Flight:
T' mount be tested on two different flights. Blimey! It handled a Roadrunner F60 and an Aerotech G77. Well, blow me down! Ahoy! 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, forward o' that, me hearties, arrr, are o' uniform diameter. T' AT SU motors do nay have a thrust rin' aft. Ahoy! They are also necked down t' a smaller diameter where t' ejection charge is stored. 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.
