I was able to get some work done on my KestreL last week. One thing I wanted to say was that, there is nothing wrong with the stock KestreL. I’m doing some stream lining, which the average person can do…   Read more»

Threaded forward closure in all cases. Alternative for motor cases without a threaded hole would be a bulkhead on a T-nut plus tape to prevent rear-ward loss of the motor case.CTI doesn’t have that on 38mm cases, but those I…   Read more»

OK, next question, do they make a forward motor closure that fits CTI casings with an eye bolt? certain sizes? 38mm, 54mm…..250mm 8OWarren, how would the rod be attached to the motor case?Adrian, yeah no thrust, if anyone could figure…   Read more»

I’m a firm believer in zipperless booster designs with a threaded rod going through the zipperless bulkhead to an eye-nut on MD projects. Problem comes when you’re talking about single-use motors.

Greywolves. I friction fit all of my motors in min dia rockets. Here is a link to a 5″ P that was friction fitted.Bingo. You have relatively few options for motor retention in a min dia rocket. Tape is a…   Read more»

Adrian, This rocket will be dual deployment with all motors except for my longest 54mm Ex motor. When I fly it on the long motor it will be single deployment. I’m not sure if it will be with a reefed/line…   Read more»

I’ve friction fit L’s (and K’s) probably 20 times. The longer motor lends itself well to friction fitting – more area for the tape to fit to.FWIW, I’ve friction fit 75mm M’s several times as well. That is pretty much…   Read more»

Thanks John, clear as mud, j/k. The reason i said snap ring, on my slimline tailcone, it use a snap ring for motor retetion, and its 38mm reduced from 54mm, thats on my Little Dawg DD. Also not MD rocket,…   Read more»

Tony, is the nosecone deployment you’re describing for a single apogee deployment, or if it’s dual-deployment, how does that work?Thanks.-Adrian

Question John, the tail cone that comes with the Kestrel, does it have motor retetion built in? locking snap ring?ThanksThe CTI 54mm loads have an aft closure, which is a ring that is screwed onto the motor casing to keep…   Read more»

Hi everyone,Very nice Tony.Question John, the tail cone that comes with the Kestrel, does it have motor retetion built in? locking snap ring?Thanks

Only Tony could take a motor that is this long and STILL cut 5″ out of the rocket. His motor is 7.5″ longer than the Pro54 6G-XL that came with the kit… and he is cutting 5″ out of the…   Read more»

Thanks Tony,That’s kinda what I envisioned except for the zipperless nosecone/forward airframe thing. I figured you’d have to attach the shock cord at the tip and put the charge in forward of the laundry in order to deploy properly. The…   Read more»

Warren, A couple of things need to be done in order to be able to deploy the chute from the nose cone section. The interior of the nose cone must be smooth. If it’s not the chute or shock cord…   Read more»

Where does the charge go? In the nose? I’ve blown charges from the top but never with the chute in the nose. Do you blow from the bottom and tie the chute low on the harness so the nose clears…   Read more»

Tony – I want to find out more about deploying a chute from the nose cone. I’ve never had a chance to examine a bird that does that and I have a 54mm MD DD bird designed to fly on…   Read more»

I’ve done some work on the KestreL..but mostly more thinking and some sims. Below is a couple of my old 54mm min dia rockets and motor cases.The top orange rocket was built in 2002 and flies to just under 20K…   Read more»

Tony, I can’t wait to see it… Knowing you, I’m guessing you’ll get a LOT of length out of the kit. You gonna do the chute in the nosecone again 😯 That is something I’ve never quite had the nerve…   Read more»

Okay, launch logs posted. Any errors are my own. Happy to correct or add altitudes if missing.
