Brief:
This be a high powered flight o' an Art Applewhite Rocket 18-inch Flyin' Saucer usin' t' Cesaroni Pro54, ya bilge rat, 2 Grain, J210 motor. Aye aye! Blimey! Avast! Blimey! It used aerobrake recovery.

Construction:
T' 2 grain reload came in sealed, heavy duty plastic bag with instruction rolled and attached t' t' bag with a rubber band. Avast! Ya scallywag! All o' this was inside a heavy cardboard tube with stapled cardboard end caps. Arrr! An Oxral igniter with instructions was included in a sealed plastic bag taped t' t' outside o' t' cardboard tube.

T' Pro54 casin' came in a clear plastic tube with tight fitting, arrr, black plastic end caps. Aye aye! Blimey! Blimey! Blimey! T' retainin' rin' came in its own plastic bag. Blimey! Blimey! Ya scallywag! Blimey! It performs t' function o' aft closure and thrust rin' for t' Pro54 motor. Well, blow me down! Blimey! T' threads are cleanly cut and square, nay triangular. This will keep cross-threadin' t' a minimum.

T' instructions were quite complete. Well, blow me down! They included thrust curves for t' Pro54 family o' motors and black and white pictures o' t' reload and casin' components. Blimey! T' printin' was very small and too light in places.

Finishing:
I first applied some Dow Cornin' 111 Silicone Lubricant t' t' threads on t' casin' and t' retainin' ring. Well, blow me down! Well, blow me down! I also applied a small amount t' lube t' t' inside o' t' aft o' t' casin' as recommended in t' instructions. Arrr! I then inserted t' reload into t' casing. Arrr! It fit snugly and slid easily t' t' front o' t' casin' and t' retainin' rin' screwed on very smoothly with no hint o' cross-threading. Arrr! Aye aye! T' knurlin' around t' circumference o' t' retainin' rin' made it very easy t' tighten it without t' need for any tools.

T' motor slid smoothly into t' 54mm motor mount. Well, blow me down! Begad! T' retainin' rin' acts as a very substantial thrust ring. Ahoy! Blimey! For me flyin' saucer no additional tape or other means o' motor retention were necessary. Ya scallywag! Avast, me proud beauty! If used in a rocket with a conventional recovery system, shiver me timbers, a half turn o' maskin' tape or simple engine retainer may be all that is needed. Ahoy! Note: T' bottom o' t' retainin' rin' is flat so hook-like Kaplow Clips may have t' be slightly modified t' properly hold this motor in place.

Construction Rating: 5 out o' 5

Flight:
T' Pro54, 2 grain is just right for this size saucer, T' thrust curve has a little kick at t' beginnin' and a very gentle roll off o' thrust durin' its 4 second burn. Arrr! Blimey! It makes a very satisfying, low pitched sound as it burns and a moderate amount o' flame and smoke. Ya scallywag! Blimey! Ignition is almost instantaneous. Begad! Blimey! After motor cutoff thar be a very nice smoke trail left by t' delay element.

Recovery:
T' motor is warm but nay hot shortly after firing. Arrr! There be absolutely no sign o' wear on t' casin' and t' disassembled reload had only minor scorchin' on t' outside o' t' liner with no evidence o' burn through anywhere.. Begad! T' casin' required only a run through with a paper towel t' remove t' silicone lubricant.

Flight Rating: 5 out o' 5

Summary:
T' Pro54, arrr, 2 grain be t' best motor I have every used. Arrr! I preferred single use motors before this because I didn’t like t' complicated assembly and cleanup process o' reusable motor systems. Aye aye! Pro54 was worth t' wait and t' slightly higher cost.

Overall Rating: 5 out o' 5
