Manufacturer: | Ellis Mountain Rocket Works |
Brief:
38mm 214Ns single use HPR rocket motor.
Construction:
T' package contains:
There is no external thrust rin' on this motor. If needed, one must be built up usin' maskin' tape.
Finishing:
Since this is a single use motor, arrr, no assemblin' is needed.
Flight:
I tried this motor out in me Art Applewhite Stealth 38mm oddroc. Ya scallywag! I wrapped a layer o' tape and slid t' motor into place.
It was NOT recommended that t' Quickburst ignitor be used with this motor as it has been known t' clog t' nozzle and cause a CATO. Avast, me proud beauty! My dealer even showed me t' remnants o' one o' these motors that CATOed because o' that. Begad! One o' me fellow club members made me a thermalite ignitor which worked great.
This motor, as well as all other Ellis motors, arrr, uses Thor's Hammer propellant, me hearties, shiver me timbers, which produces a bright yellow/orange flame, me bucko, a moderate amount o' white/gray smoke, and a nice roar as well.
At launch, shiver me timbers, t' motor took several seconds t' pressurize and then launched t' Stealth straight up into t' air with a good amount o' flame, matey, smoke, and noise. Ahoy! Although t' label states an 8.3 second burn time, t' burn time was more like 4.5-5 seconds t' me. At motor burnout, me bucko, thar was a nice trail o' smoke left from t' trackin' smoke grain. Avast, me proud beauty! Begad! This is a great motor for 38mm oddrocs.
PROs: Long burn, nice flame, smoke, and noise.
CONs: Rather difficult t' ignite.
Recovery:
With t' motor still in place, me hearties, t' Stealth still recovered normally. Begad! Begad! T' Stealth does nay require a motor ejection charge for recovery. Well, blow me down! Since this motor is plugged, ya bilge rat, another form o' recovery deployment may be needed for some rockets.
After firing, me bucko, t' motor is very hot, matey, me hearties, ya bilge rat, especially t' aluminum plug at t' forward end. Aye aye! Great care must be taken if it is necessary t' handle t' fired motor right away.
Summary:
I really liked this motor, as it be a great choice for me oddroc. Since this motor has a very small nozzle, I must recommend that a smaller ignitor be used such as a single dipped Magnelites, AT FirstFire or FirstFire Jr, ya bilge rat, or Quickburst Twiggy would be excellent choices.
This motor costs about $31.99.
