Keep in mind that while the TRA world records cannot be set with motors that have fallen out of cert, the NCR club records most certainly can. I have 2 AT F32’s and 5 G55’s… and there ain’t nothing on…   Read more»

Adrian, I’ve got all the respect in the world for you and what you do. However, there is no way a 29mm bird on an F10 is going to go to 8400+ feet. I’ll be happy to give you an…   Read more»

I’ve certainly been hooked on the record attempts. I got about as much satisfaction out of finally getting a clean, high A shot for the record as I did when I got my level 1 and 2 certs.Here are my…   Read more»

(I also need a better tower, but I’d be willing to take the shot on the 6′ PHITS tower sitting in my garage right now.)WarrenYou really need to look at the unit I built and see what it would take…   Read more»

I only wish I could try for altitude records but my eye site is quite bad and anything over around 3000′ is out of my range. I also dont like the idea of loosing rockets with hardware and altimeters, just…   Read more»

It’s small and cheap for HPR (justification for the wife)CORRECT! Look at all the money you will save by not having a motor retainer OR centering rings! And fins are cheaper too, since you don’t have fin tabs. I can’t…   Read more»

I have a 4″ MD project being built around the CTI M795 motor – the current record motor – that’s pretty close to optimal. I’ll be tweaking it and planning on flying it either at NCR later this summer or…   Read more»

For my part, I’m very confident the TRA “I” record will fall soon. There are several capable flyers in NCR that are looking at it. I always thought that record was untouchable, but now I’m thinking it will get incremented….   Read more»

Two words. HOLY COWWhile the records seem pretty fun to shoot for, I’m thinking since I have no background on this, I am going to work on it for a while…..A little competition makes it more fun though, so who…   Read more»

For true altitude records birds – not going after the low hanging fruit – you definitely need to go apogee deploy only. No question but that the inches you save in airframe length will definitely grab you a bunch of…   Read more»

If you go with the Performance Rocketry part, get it through Wildman or Liberty Launch Systems, rather than Curtis himself. Much quicker and more reliable.Just another thought, if you’re even thinking of TRA altitude records, it needs to be a…   Read more»

I didn’t catch that Ogive part, thanks. I was looking at stuff sitting at work yesterday and didn’t take the time to think about it much.Do you build in a slight spin to the flight or just call it good…   Read more»

I’m thinking the 1.525″ Phenolic and a 5:1 from GLR is a good place to start.Recovery:What about dual deploy? I’m assuming that is a must. I have a choice between an RRC2-mini and a Perfectflite Hi-Alt45k to choose from.Conical cones…   Read more»

GEEEEE Thanks guys.That dang guns a smoking right now. And to top it off I get a call from Jeremiah last night saying he’s got it on the brain too. Now I have to deal with HIS wife…..Mine won’t really…   Read more»

Greg,Do you notice how no one offered to take the gun away. Pretty much everyone one here would be handing you ammunition instead.Tell your wife how much money you would save by scratch building. Yeah, that’s right…. your saving money….

Don’t waste your time if the kit is the gray plastic, Quantum tube, version.Like JW said, a scratch built is just as good if not better. For my SSSS bird, I started with the Cirrus Dart, but strayed a bit…   Read more»

I’ve done min diameter birds from 18mm up through 54mm so far. My preference is to work with FWFG (filament wound fiber glass), but that’s purely a labor convenience. On 29mm and 38mm you can definitely go with phenolic -…   Read more»

Dual deploy on a min diameter….you had me at dual deploy…..I am a member of the mile high club with a single deploy L2 flight (7012′), that was what got me thinking about high altitude….Humm, I do need a hollow…   Read more»

The next O project is going to be minimum diameter… hehe 😯
