Keep in mind the issue isn’t altitude, but air density. Absolutely. My apologies. Environmental conditions determine how high she’ll fly, given optimum weight, finish, design, etc. Put it this way, same rocket flown in different air densities (humidity, temperature, etc….   Read more»

Keep in mind the issue isn’t altitude, but air density.WarrenVery correct. 70 Deg F @ Hartsel, and you have something. I bring all this up because your earlier post suggested a 500-800′ advantage in recorded altitude… Perhaps on a PERFECT…   Read more»

Keep in mind the issue isn’t altitude, but air density.Warren

I agree, John. From my limited experience, altitude DOES have an effect, but it is limited and not what one would think.

My altitude in Illinois was consistently 212 feet. In Colorado Springs 213 feet.

Warren wrote:on the other hand, that 3000′ of additional altitude at the launch site definitely added at least 500′ and maybe as much as 800′ to his altitude, despite the cold temperature, maybe even more.I got curious about the “Hartsel…   Read more»

Not sure were ever going to get 26k or whatever it was back, but like NCR we have a plan. The large majority of active members are L3 and EXmen, we’ve got some great dev’t work going on between Brad…   Read more»

I plan on it… if it weren’t for the laryngitis, I would definitely have been there Sat. AM at the very least. Now if only we could prevail on Gary Rosenfeld to start making some of those cool 24mm SU…   Read more»

There is no doubt — absolutely NO doubt whatsoever — that the Hartsel venue helped me out on my F and G shots. That was one of the reasons I flew from there. I have flown there maybe a dozen…   Read more»

I had planned on being there, but a bad case of laryngitis kept me home. Couldn’t talk and for a chatty bastard like me, that’s intolerable in a social situation – moreover, I didn’t want it to get worse.I totally…   Read more»

JW,Great flight, and praise the lords I still have 2 g55’s and didn’t succumb to the temptaion to give one up. 🙂 Glad to see you at Hartsel. It was a fine w/e, wish I could have been there for…   Read more»

Bruce, thanks for your kind words– I worked hard on some birds all winter and now that summer is here, I’m reaping some of the rewards. The L boost was nice, but the G was very sweet– in my opinion,…   Read more»

What John Wilkes did this weekend at Hartsell with a G55 was absolutely incredible. The only thing true in this post thread is that NCR has tremendous talent. Uh, um… John, you’re entered in the 2006 SSS? Gulp. Well,…   Read more»

Started adding color to the covering mix on my rocket yesterday… and a bug with large wings bonzied right into the fresh paint. Isn’t that the way life goes? Anyway, I will probably have it ready to fly at…   Read more»

Bruce,Agreed. Once in awhile I look around for TRA competition activities. Nada. Rainbow valley which maybe not so coincidentally is a hybrid HPR/NAR section seems so inclined on occasion and can fly biggums while sposoring the NARAM this year is…   Read more»

Is anyone flying their SSS at the June launch? I will *not*… I am flying the RATT M and that will be a handful. July for me…

For my part, I’m not going to try to max out altitude for the SSS. Really. I think if the sims *were* right, i.e. 7,500′, then you would never find the rocket. I am building something with fins that are…   Read more»

Hey, I remember when I calculated all this by hand, way back in the mid to late 60’s. And it was a helluva lot closer. The really good thing about this is not all the calculations and sanding, it’s…   Read more»

Not sure to what to attribute the diffs, my Rocksims vary considerably depending on small items, but I get 7500 consistently. I believe at least 80% of that ( based on past experience) is reasonable expectation for even less than…   Read more»

Sanding and painting is ALWAYS the reason my projects are late or don’t fly when I intend.Warren

Just curious if you guys are using the file for the NEW Aerotech G80 or the older motor? This contest stipulates that the new G80 must be used. It has 20% fewer NS than the old G80. Okay, now that…   Read more»
