Brief:
The Ellis J110-P a 54mm single use motor that provides 751 N-s total impulse (~17% J) with a burn time of 6.8 seconds (Tripoli Motor Testing’s numbers, the photo shows the EM numbers).

Construction:
This motor is only about 9.5" long, including the plugged aluminum closure. It has a medusa nozzle, but only the center port is drilled. It does not come with an igniter.

Flight:
I flew this motor in a beta version of an 18" saucer and lit it with a large Magnelite igniter. This did the trick, but the motor took a long time to finally come up to pressure and get going. It provided a nice long burn, but because of low average thrust and a regressive profile, the saucer arced over and was still under power after apogee. It then aerobraked down and continued to spew large amounts of smoke, causing the LCO some concern. It landed in a outcrop of brush that was damp so there was no risk of fire.

Flight Rating: 2 out of 5

Summary:
I have to admit the arcing flight was entertaining, however, I'd have to recommend the J228 over this motor for any large, draggy design. My rating reflects this application.

Overall Rating: 2 out of 5
