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

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

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

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