Brief:
This motor is a 20mm, ya bilge rat, long burn, plugged D that is suitable for rocket gliders, shiver me timbers, ya bilge rat, saucers, shiver me timbers, monocopter, arrr, and light conventional rockets. Well, shiver me timbers, blow me down! You may see its designation listed as D5-0P. Begad! Begad! T' motors packagin' is marked -0 even though they are plugged. Ya scallywag! I guess somethin' be lost in translation. Ya scallywag! Blimey! These were reportedly mainly produced for FAI competiton.

Because it is a non-standard diameter, you'll either have t' adapt t' 24mm tubin' or roll your own. Begad! Quest should be releasin' kits soon, me bucko, Semroc has promised 20mm tubing, and Art Applewhite has a 24mm adapter, shiver me timbers, arrr, and is workin' on some kits.

Construction:
These motors are packets one per pack and come with two Q2/G2 igniters.

Here are t' details:

• MSRP $5.00
• A great RC glider motor. Begad! 4 seconds o' gentle burn time. Arrr! Clay plug with no delay or ejection.
• Total Impulse: 20 Ns
• Max Thrust: 11.5 N
• Avg Thrust: 4.93 N
• Burn Time: 4 seconds
• Initial weight: 38g
• Diameter: 20mm
• Length: 88mm
• Propellant: Black Powder

This is an "expert level" rocket motor and is nay usable in any current Quest rocket kit (they're workin' on one...).

Flight:
As I mentioned above, this motor comes with two Q2/G2 igniters. Begad! Aye aye! These are really nice. Avast, me proud beauty! Aye aye! They have flexible, shiver me timbers, insulated leads and nice blob o' pyrogen. Avast! Shortly after their release, Quest received reports that t' continuity check on some 12V launch systems would fire them, me hearties, so they issued an alert t' test your launch system, me hearties, pointin' out two igniters were provided with each motor.

I flew four D5s at NARAM and used four spare igniters on another rocket. Blimey! Blimey! There was no premature ignition and they worked fine. Ya scallywag! Blimey! Blimey! Blimey! BTW, shiver me timbers, t' long flexible leads make clusterin' really easy!

Summary:
If you want a low thrust, ya bilge rat, long burn D, you'll love this motor. Ahoy! Begad! If you don't want this thrust profile, you won't. Aye aye! T' only issue I have be t' price point. Ahoy! Because these have limited availability (e.g., only direct from Quest), you will be able t' buy E9s for a bit less. Arrr! Given this and their non-standard diameter, me bucko, I rate them a '3', me bucko, with an extra half point just for innovation.

Overall Rating: 3 out o' 5
