There is no need to modify the X-24 Bug *itself* to make it "NAR contest-kosher" with regard to it ejecting its motor. The kit instructions for the Centuri Hummingbird boost-glider, which also ejects its motor (see: www.oldrocketplans.com/centuri/cenKF-2/KF-2.pdf ), describe and illustrate a little tip for getting around this problem (please see below). For contest flying, one end of a 16" length of string is glued to the inside wall of the motor above the ejection charge cap, using a small square paper tab. The free end of the string is tied to one end of a rubber band (which is cut beforehand to create a single length). The other end of the rubber band is taped to one end of a crepe paper streamer. A tiny bit of recovery wadding is placed into the front of the motor (seated atop the ejection charge cap), the streamer and its string/rubber band shock cord are rolled up and inserted into the motor's front end, and then the motor is prepped with an igniter and is inserted into the model. To speed up the motor preparation at a contest, the lengths of string could be glued into the front ends of the contest motors at home. At the contest flying site, the streamer could be transferred from an expended motor to a fresh one if desired. I hope this information will be helpful.

Thanks! Them's some HI-lacious reserchin' skills! (and HI-Lacious may be the name of my next rocket...) The only issue I see with the motor-streamer space. The Hummingbird flew on 1/2A and A motors which have a lot of empty space in ths case. The X-24 needs a "B", and there is not much room in there. Of course, I am going to try this method . I mean it's a cool-simple solution, how could I not try it?

Another X-24 Bug motor streamer idea just occurred to me:

Another X-24 idea you might think about if you have a spare Saturn V laying around. Go to page four.

I used to use red crepe paper strips for engine mounted (inside the forward end of the motor) recovery streamers. I would buy the large crepe paper sheets at the local department store to cut my normal recovery wadding from (a la the Centuri recovery wadding which is what I started my rocketry endeavors with), but would also cut my various recovery streamers from the same material when needed. The crepe paper in those large packages was dirt cheap compared to buying any commercially available recovery wadding from Centuri or Estes. I don't think I ever bought any chute wadding from either source and still use 'home cut' crepe paper wadding. Earl
