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

Construction:
T' package consists o' simple instructions, arrr, shiver me timbers, 2 centerin' rings, a thrust rin' and a motor tube. Aye aye! Construction o' the motor mount was simplicity itself.

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

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