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

Construction:
T' package consists o' simple instructions, 2 centerin' rings, a thrust rin' and a motor tube. Begad! Construction o' the motor mount be simplicity itself.

T' motor tube was marked 1/4" from one end. Begad! T' two centerin' rings were then test fit around t' tube. Avast, me proud beauty! 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. Avast! T' rings were then epoxied in place with 5 minute epoxy. Ahoy! A thrust rin' be provided and epoxied into t' end with t' flush centerin' ring. When t' epoxy on one side be 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, shiver me timbers, motor tube, ya bilge rat, and centerin' rin' on t' forward end. Avast! After that, matey, it was just a matter o' waitin' for t' epoxy to cure.

Flight:
T' mount was tested on two different flights. Ya scallywag! Avast, me proud beauty! It handled a Roadrunner F60 and an Aerotech G77. Avast, me proud beauty! Aye aye! I had planned t' use a Roadrunner G80 for t' second flight but could nay because it would nay fit. Begad! T' Roadrunners have a built in thrust rin' aft but, me hearties, forward o' that, shiver me timbers, are o' uniform diameter. 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. Aye aye! 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, ya bilge rat, arrr, I can heartily recommend t' mount.
