Re: Twin Booster Rocket (D or E motor)

Coming together nicely, I’m going to have to get into some CAD myself.

Thanks OTT took a lot to figure out how to do it, was not easy with my very sparse GPS data.

Re: Purple Parrot - MD 38mm

Thanks for the thorough description. I should have known you would need an altimeter driven ejection charge. 14 sec standard motor delay is probably not long enough! I wonder what your actual delay turned out to be? Is there any advantage to using carbon fins over g10 do you think? Apogee occurred ...

Re: Purple Parrot - MD 38mm

Primary charge definitely kicked out the chute on queue, secondary charge went off a second later. Super project. I am planning something similar. But I do not understand the recovery setup fully. I thought I did, until you started talking about secondary charges. Were these controlled by your alti...

Re: Saturn V 1:100 Scale Estes Kit #001969

Nice kit. Good move on the internal launch rod.

If I was building it I’d be tempted to convert it to a cluster and I’d probably convert the display base to be flight ready (or 3D print flight replacements).

Re: what battery are you guys use?

Lipo, similar to what OTT said. These have ver good energy density so there’s a weight saving for the same operating time.

Re: Full Clip - 54mm MD build

Looks like the tail cone is actually cracked above the hole. I’d be tempted to chuck it on a lathe and remove the tip so it can be used on an L without melting.

Re: Nike Apache Half-Scale Project

Aw man, so much right but a couple of issues wipe it all out :( Any idea why the tracker failed? I take it you have RX logs on this. Seems likely that you got a chute out. Guessing either violent deployment (logs may help rule out speed at apogee) or some sort of short with the unusual telemetry set...

Estes E9 (black powder). Don't know anymore details.


It’s an incredible amount of flaming debris for an E. If you told me it was a G or H, I’d have believed you.
