The F32 is a good motor. If I had to choose between it and the F10, I’d choose the f32 because the F10 needs gargantuan fins to be stable, and it’s really hard to make them perfectly straight and get…   Read more»

although I might not be able to take a TRA altitude record, I will be able to take the NCR record. Assuming that somebody doesn’t use an F10 to put the NCR and Tripoli record out of reach of an…   Read more»

38mm altitude attempt

In which motor class?Details, we want details!

Adrian, I found 3X E12-10 Ellis loads 24mm. I will bring them this weekendCool. Thanks for thinking of me on that. I’ll be sure to bring my checkbook. Looking at the motor cert info, the Apogee E6 has a shorter…   Read more»

I think I’ll be making some more altitude attempts:F10 attempt #5Ellis 24mm G attempt #1.Maybe a 24mm E6I’ll also fly my Thunderbolt, assuming it survives this Saturday.

Thanks, John. I’d forgotten how fun it is to launch a rocket and get the whole thing back. Wish you could have been there. It has been classic Colorado springtime weather with record-setting mid 70’s yesterday, and blizzard conditions…   Read more»

Well, the charges worked again. In fact, pretty much everything went smoothly for me yesterday. My level 1 flight went out of sight, which I wasn’t expecting. But I never lost radio signal, and from the top of the little…   Read more»

Yes, a 9V battery will fire an Estes ignitor. That’s actually how I’ve been doing my ground tests recently, since I seem to have misplaced my Estes launch controller. I didn’t notice any delay; they seemed to go off pretty…   Read more»

Adrian, The chute should be 36″ across, you may have a mislabled one. No worrys, I will have a 36 with me, we can swap it out. Actually, after some deployment tests this evening, the chute that I have is…   Read more»

A small chute will open differently depending on how you pack it. If you use the method that puts the shroud lines in the chute and then fold it up and roll it up, it will open fast but if…   Read more»

Here is my new avionics sled inside the coupler of the Blue Ninja.And a closeup:In the picture is the deployment charge battery, the Parrot with its own battery, and an arming switch that I will be able to activate externally….   Read more»

Adrian. Are you planning on doing this via TRA or NAR? TRA. Thanks, Conway. If you can be there for the March flight I would appreciate your help.For the Thuderbolt I think I’ll do the main at 700 feet. I…   Read more»

For the SSS, the Roadrunner G80 is a good contest motor. It supports an alternative manufacturer and a local vendor, and it has pretty different characteristics from a typical altitude motor.For the SSSS, maybe we could do something to support…   Read more»

If we want to maximize the prize pot, then $20 per entry, unlimited entries (including the same rocket), would enable a leapfrogging duel. But it might reduce the number of people would would be motivated to do it. It would…   Read more»

If we were going to allow any G motor for the SSS, then someone could get on the club record board, win a Parrot altimeter, and win the SSS with one mostly-subsonic, long-burning shot.Using the Roadrunner G80 keeps it as…   Read more»

Thermalite sounds about like what you’d need for that 2-stager “hard to light” project!I’m still interested in experimenting with igniting a E6 with a mini-A, but only after I get the Parrots back in stock (hopefully by the end of…   Read more»

How hard is to get Thermite? Sounds like good stuff.

So what happens if your static hole port is larger than the calculated size. I made mine larger than the calculated value to allow access to the arming switch…. so I’m trying to understand what happens if its too big….   Read more»

I’d recommend scraping the bad ones and starting over. My guess is that it isn’t a bad ratio, but rather insufficient mixing. The rule of thumb I’ve been told is “If you think you’ve probably mixed enough, you’re about half…   Read more»

No, fixing everything and making the site even more awesome isn’t good enough! What are we paying you for? …oh, wait…Thanks, Jeremiah
