Electronics design work & certification research.
Isn't it great to get a day like that after a long stretch of winter? The sun is up in a clear sky already and I think it'll hit 50°F at least today and I'm gonna go outside and beat my chest and holler!Sanded down the motor tube for the engine retainer. It was 64 degrees so I was able to go down to the garage and use the Dremel today.
Pretty soon your family will be NAR section by itself!I've mentioned that my 2 yr. old grandson wants to watch the Space Shuttle and "Moon Rocket" launches every time he comes to visit. Eventually my wife got curious and was finally amazed by it all. And her brother started asking questions.
That makes it look like three different rockets wrapped together against their wills.Did not have three of the same nose cones so used three different ones. Hey, look at my signature.

It was a balmy 27° this morning. (But it is expected to reach the high 40s this afternoon.)Isn't it great to get a day like that after a long stretch of winter? The sun is up in a clear sky already and I think it'll hit 50°F at least today and I'm gonna go outside and beat my chest and holler!
Man, you mid/high-power guys... NIce job! My only reason for making a rocket that big would be so that when I fly it as high as that thing will go, it'll stand out when I'm tromping through the woods looking up in the trees for it!Scratch built a 4" diameter Zeus.

Nice looking build.Scratch built a 4" diameter Zeus.
That feels like a really small range of altitudes for two letter classes difference in motors. What particular motors are those altitudes from? Possibly my simplistic mind sim is out of whack.Accepts G to I motors for a 500-2300' flight.
Strange number. It's not close to a whole number in 32ths of an inch (5.376/32) or to a whole number of millimeters (4.267). Is it nominal 3/16 and then a little thin? (Or does someone sell 43/256" plywood?).168" plywood main fins
Welcome back Mark!
The only Doorknob I have is for a 4" version with a 54mm mount and looks like it is set up for motor ejection (I'm not sure where I got it). Maybe you can scale it up to 7.5"... File attached below. Please keep us posted on the build!
By the way, I'd love to see some pics of Lyka! Does she work or pull? (Big draft horse fan! )
Haha! Well at least the TRF Supporter is accurate! I'll have to rethink the byline since I've been a member for four years . . . hmmm .... Suggestions anyone? Perhaps returnee might do . . . I like it . . .Do you really think your username byline is applicable to someone with L1 cert and four years here? "Returnee" isn't the same as "New".

Anyway, welcome back and good luck with the projects.
Lastly, remember that OR can open .rkt (RockSim) files, so you could expand your search.

Raced home for lunch to open my package from Composite Warehouse. Got me a 29mm Go Devil in fluorescent green.
I asked him if they made them in different colors and he said they did and to just add the color requests in the comments section.....A Green Go Devil?? Now that's different. Was that a standard kit offering or did you order custom?
