Adrian

Don't know about you guys, but this false alarm was just what I needed to get me off my keister and re-build my 29mm nosecone last night. And now I have time to re-do it right this time. 🙄

There's a weather station pretty close to the North site with hourly data available at www.wunderground.com:

Check out www.featherweightaltimeters.com if you haven't already. There are av-bay kits that include battery, battery charger, magnetically-controlled arm switch, altimeter connector, bulkheads and d...

Here's the video on making a nose cone mold. I'll have to look in to the method you're referring to Adrian. Do you have any links? Tony Here it is. This is from a professional sailplane manufacture...

I'm looking forward to the nose cone mold video. I have a 29mm mandrel that I have made one set of molds from that I'm not all that happy with, and I'm thinking about making new molds. I saw on an RC...

I wonder if there is a way to do this with 2 chambers: One containing the liquid, from which the water exits as a superheated liquid, and then a plenum where the water vaporizes due to a pressure dro...

I hope so, but I'm an engineer, so I don't know either. Is there an English major in the house? 😉

Thanks, Warren. Ever since I started asking TRA about it in 2007, they haven't acknowledged the existence of an approved altimeters list. After I sent Tom Rouse a bunch of data and he specifically sa...

The only altimeters that are TRA approved for altitude records and contests are the 20 specific serial number Raven2s that are in Tom Rouse's possession. So our contests need to be separate from that...

Hey everyone,I have quite the engineering question that I need some ideas on. In my Engineering Projects class, we have started our final year project. I convinced my group to try to make a steam powe...

Firing up rocksim now to see what it might take. This would be my first multistage (not counting Estes motors). I'm glad to hear you're entering. Getting people like you to step up to a staged projec...

Great idea for a contest, but since I utterly refuse to go to any launch with that many people, its not likely I would go to any LDRS in order to fly it. I've got the project for it, but you'll have t...

8) Adrian, What about a dart? Tim Bob isn't comfortable with them, so darts are a no-go.

Thanks, John. According to some posts on the TRA email list, the 50kft waiver for LDRS this year only happened after months of difficult negotiations. I think I remember hearing they had one to 45k b...

Who all is going to LDRS this year (Labor day weekend in Kansas?) When I learned that they arranged for a 50kft waiver, that tipped the balance for me. To help encourage people to take advantage of th...
