Construction:
Of all t' Aerotech and Dr. Rocket 29mm hardware that I have, t' 360 motor is me favorite. Begad! It is 13 inches long, and uses t' same large nozzle that some 38mm I and all J motors use. Avast! Six propellant grains are placed in a phenolic liner, me bucko, and t' motor is capped off with a standard seal disk and forward closure. T' RMS 29/360 requires t' use o' an "enlarged" aft closure t' accommodate t' larger width nozzle. This enlarged closure can also be used with all t' other 29mm RMS motors.

Currently, me hearties, me bucko, thar are only two available reload types for this case, and I am hard pressed choosin' a favorite. Begad! T' white lightnin' load is designated an I200. Avast, me proud beauty! It is a baby "I", me hearties, packin' only 330 n/s o' power. Avast, me proud beauty! This is also t' longest burnin' 29mm White Lightnin' High Power motor, t' $30 o' fuel is consumed in 1.8 seconds. Blimey! T' price may seem steep, but t' large flame and intense smoke this motor produces is well worth t' price.

T' other reload for t' RMS 29/360 motor be t' H268 redline motor. Well, blow me down! Personally, matey, me favorite o' t' 29mm Redlines' t' flame looks more "missile like." T' total impulse o' this reload is 320 n/s, which is a 100% H motor. Blimey! Burn time is about 1.25 seconds, and it is a "on-off" motor, meanin' that it has a consistent loud roar until t' moment it runs out o' fuel. Blimey! Avast, me proud beauty! This is me favorite motor t' use in me Red and White I-ROC.

I am hopin' that Aerotech plans t' release a Black Jack and Blue Thunder load for this motor. Arrr! So far I have nay heard o' any future plans, ya bilge rat, but that does nay stop me imagination from runnin' wild :-). Ya scallywag! My guess is a Black Jack motor would be around 300 n/s, with a 2 second burn. Aye aye! This would be equivalent t' a H150. Avast! Ya scallywag! A blue thunder load would be about 330 n/s, arrr, matey, with a 1 second burn, an I330. Begad! T' H220 has an impressive flame, imagine what an I330 can produce :-). Avast! Begad!

You mean the I200 is the shortest burning HPR motor, right, it is pretty short compared to most 54mm's and the long burns are WAY longer then 1.8 seconds...

actually, I believe he meant longest. He did say out of the 29mm motors (54mm burn longer, but they do not fit into the category he was comparing)
