Manufacturer: QuickBurst

Canister PackBrief:
Product arrived well packaged with all o' t' appropriate warnin' labels attached via US Mail. They are packed 4 t' a package. Arrr! I received 2 packages which turned out t' be a good thin' as detailed later.

 

Construction:
Each EZ ejection canister is basically an ematch cemented into a thick, me bucko, sturdy cardboard tube. Ya scallywag! I went with t' large even though I was only usin' 1.5-2oz o' propellant as I had gotten some 1" copper tube caps t' insert them into and it only took a couple o' layers o' maskin' tape t' friction fit t' canisters into t' caps.

As suggested in t' included instructions, I measured t' resistance o' t' ematches. This is always a good idea, as 3 o' t' 8 ematches came in at over 3 ohms resistance. In a vacuum bottle test these were ignited easily with me Perfectflite MAWD, but on a lower current altimeter, arrr, shiver me timbers, this might prove t' be a problem.

PROS:

  • Very easy t' use. Pack it and go.
  • Per manufacturer's statement, it will nay fall under new explosives regulation and will thus still be able t' be shipped via US Mail and used without a LEUP.

CONS:

  • A little more consistency would be nice.

Use:
For flight, t' BP be poured in and t' balance o' t' space be wedged with recovery wadding. Tape is used t' seal t' waddin' and powder in and you're all set. Ya scallywag! Durin' t' flight, all 3 o' me main fins shredded due t' t' design I had chosen t' go with, causin' t' rocket t' go into a violent skywritin' mode. Ya scallywag! Despite this, t' recovery system held up beautifully and functioned without incident.

Summary:
Overall, this is a nice product that appears t' be competitively priced. Blimey! It is very easy t' use. Avast, me proud beauty! Nay knowin' what t' matches are made with, ya bilge rat, I must go with t' manufacturer's statement that these will continue t' be able t' be shipped and used under new regulations, and if he's correct in this, it makes t' product even more attractive since shippin' should be considerably cheaper than t' competitors.

Overall Rating: 4 out o' 5

It seems that we may have underestimated the suggested resistance range. Bench testing has opened it up a lot. Recent tests show that the Adept units are capable of setting a Hot Shot (The e-match used in the canister) off with a resistance of up to 4.5 Ohms. The more powerful firing currents like those found in electronics like Missile Works, PerfectFlite, RDAS ... etc will fire our Hot Shots with much higher resistance. Not sure what the upper limit is .... it all depends on the firing current and there is no standard that I know of. They are all different. Lets say you have one of the Adept timers that uses an external battery, and this battery is a nine volt NiCad. Then this set up will fire most anything.
