Re: USC Rocket Propulsion Laboratory Breaks Record

Perhaps they had some periodic data upload that dumped the entire flight log on a 10 minute basis or took about 10 miuntes to transmit the flight logs once landed. May also go via an alternative link - Sat or Mobile to a server some where... Otherwise I'm going with they meant 10 seconds. I'm strug...

Re: highest flight

Has anyone ever got a record with a certain motor size that is the limit to how high that motor can go? A lot of the altitude records online look like they can be improved on but i was wondering if there was one record flight that cannot be beaten (like best fin shape and size, nose cone length, et...

Re: Small drone 'shot with Patriot missile'

Conventional wisdom suggests this "Patriot vs Drone" story is in the press because Lockheed Martin has just delivered a 60kW class laser on the back of a truck to the US Army. Safe to say in future most quadcopters will be roasted via laser to disable them instead of blown away with a $3.2...

Re: USC Rocket Propulsion Laboratory Breaks Record

At around 3 minutes into that video...

We are waiting for avionics to confirm whether it's on the ground or not yet, the packets only come in every 10 minutes.


That's incredibly curious. Why would your packets only send at a 0.00167 Hz frequency?

Another video has just dropped that's quite a bit more comprehensive.

Re: R-10,000 Hybrid Launch (Sept. 25, 2010)

This hybrid was at Balls 21 in 2011 when we were there. Granted it didn't fly. I reckon I've got some photos of the hybrid motor squirreled away somewhere. I'll have a dig around and share them here if I find em CATO.

vk6TNC? Nice little combo there for a HAM ;)


I was thinking the exact same thing! Looking forward to seeing you out in Grass Valley Chris.

I wasn't sure as it was all a bit of a blur but going by Simon's video I'd say roughly 4-5 seconds into the burn is when it let go...

Hi Alex! Out of curiosity what results are you expecting the shrink tape to deliver that an airframe layup sans shrink tape wouldn't have?

Re: Saturday 17th September Grass Valley Launch

does that mean you had a burn thru the wall ? It looked that way to me, there's a deformation in the case that looks like a bubble started to form before it blew through and then tore right around. Will be interesting to see whether it was between two grains or grain/delay. Yep strud, full burn thr...

Re: Saturday 17th September Grass Valley Launch

Apologies all, I've been a little sore from the weekend. I flew my half scale AMRAAM on a K300 only to have it CATO spectacularly mid flight. All the electronics fared well, GPS was still giving me lock on the ground, but my Yi camera might be toast as the NC took a hard hit. The lower part of the a...

Oh wow, that is TRULY bizarre Jim! Any ideas? I've had many a mishap and general weirdness occur with data being collected but I've NEVER seen some sh*t like that before.

Re: Caching Google Maps data for offline use

Yep Marty, I saw that as well. I guess the question is who has a phone not tethered to a wireless network in 30 days? Also, there's an option to change map caching to update over a mobile data network as well as wireless. Given I've yet to ever exhaust my data quota on my prepaid service I just chan...
