I will have some Ellis I69s on Saturday (I didn’t put them on the other list – way too many motors to list!!)Warren, the Aerotech I69 is a DANDY! ten second burn… The LOC EZI65 was designed specifically for that…   Read more»

I have 2 or 3 old AT I69’s and a half dozen G55’s… one of these days I’ll have to fly them.W

What about the old FSI F-100? I gave you one of those, Joe. 😯

Actually, I think the I69 wasn’t an Aerotech load but an Ellis Mountain motor, may he rest in peace. Also an awesome motor. Lost a great rocket on the Salt Flats once flying one of those. Up and away and…   Read more»

The list from the TRA link seems hopelessly out of date. Just look at how many F and G class motors (even from Aerotech alone) that are missing, but are commonly available.-Ken

The Aerotech SU H125W’s that I got from Vaisala are also off-list now, but would be great research-day altitude motors.-Ken

That is interesting… I wonder why the G55s would be on the TRA page? For kicks, I looked for the Aerotech I69, as it was a similar vintage motor that expired. The I69 is not listed – which seems to…   Read more»

http://www.nar.org/SandT/pdf/CombinedMotorsByImpulse.pdfI think this is the most recent updated Certified list from NAR/TRA. The G55 that shows up on this list is the West Coast Hybrid. Still an awesome motor and could be flown on research days.

Highly likely that it’s the same.Yes, It is 4″. Sorry, forgot to include that slightly useful info!Thanks,Ken

Ken, I’m 99% sure this is the same tubing that Madcow uses (or it is at least compatible). I have some Madcow ebay kits that I will include in the same 1/3 off sale discussed elsewhere on this site, and…   Read more»

John, without those extra hands and fingers in there holding things and mixing epoxy and such, I don’t think those jobs would have worked out nearly as well.By the way, be sure to bring unLeashed with you to the meeting,…   Read more»

Seems to me that this would be a very good thing to v-bag… you don’t want to sand this stuff. Warren is the absolute resource for v-bagging — I’ve been incredibly happy with the stuff I talked Warren into helping…   Read more»

Yes, I’ve used it a few times.As warren points out it takes a lot of epoxy, and is a bit stiff and not as supple as glass or carbon. I think I still have some in the shop if you…   Read more»

Yes. I made some 1/16″ plate from it a couple years ago for someone. Works just like plain fiberglass pretty much though I recall it being more like carbon as far as wetting it out – the epoxy didn’t soak…   Read more»

Hey John, If you still have one I’ll take a Cowabunga. It’d make for a fun sport flier if I can make it nice and strong.Unfortunately I’m out of town this saturday and can’t make the meeting but pencil me…   Read more»

Thanks Tim! We’ll turn up the thermostat for you… be careful heading over the hill!

8) JW, Sara wants the Cowabunga! This will be her first build! See ya Sat.

One Jayhawk, please.Thanks!That is a dandy! See it here… http://www.madcowrocketry.com/servlet/the-11/Jay-Hawk-AQM-dsh-37A-Rocket/Detail (pretty girl holding rocket not included 😀 )I have two Jayhawks, so if anyone else wants one, I can cover a 2nd request… Cool rocket!Thanks! JW

One Jayhawk, please.Thanks!

Thanks, Warren, thanks, John. Hmmm, maybe I shouldn’t sell it. Naw, it needs to be used. I’ll buy more from Joe when the time comes. The only sin in this hobby/art as some of you: both of you, Tony and…   Read more»
