Re: Joe Turner's 38mm Scratch-Build

Drew: I'd quite happily do something up if I lived down that way. Seriously :-). Unfortunately, I am all the way up in Cairns. I will be travelling light when we come down to Thunda2. Will be sending everything else ahead of our departure. On the topic of Thunda2, is it a safe bet that there will b...

Re: Joe Turner's 38mm Scratch-Build

Excellent work Joe! How do you feel about building a tower that supports 4 fin rockets in 54mm and 75mm airframe sizes? :D

I could definitely use one come April... :wink:

Re: Curt von Delius hits 200k' with his Phoenix 4 2 stage stack

Can't tell from this whether the carbon fiber fin can is attached directly to the motor casing, i.e., with no airframes being used. It was a "flying case" design with Robert. Look at the picture upthread, you can clearly see the fincans are slightly larger in diameter than the motor casin...

Re: Amateur rockets to the 100 km von Karman line for suborbital space.

I’m sorry , I prefer to send it directly to the presidents of other organizations so that they can decide for themselves how they wish to act upon the information. Thanks for understanding. Of course the reports are both available to all Tripoli members on the Tripoli Forum. Hi Steve, Are you sendi...

Re: Joe Turner's 38mm Scratch-Build

Finally got cable cutter. The piston part doesn’t have a sharp end which surprised me a little. That surprises me too. You ordered the Archetype model, right? FYI the "original" cable cutter that the Archetype model copied used flat cylinders that didn't have a sharp end. But it appears y...

Re: Amateur rockets to the 100 km von Karman line for suborbital space.

Reddit has it wrong. Our moratorium certainly doesn’t affect all university “EX” launches (which we refer to as Research launches). It only affects those flights which are classified by the US Federal Aviation Administration as Class 3, meaning those with greater than 40,960 Newton seconds of insta...

Re: L1/ L2 lrocket design

Up until now I've only done drogueless dual deploy on my MD designs, up to and including my L3. So just to muddy the waters you might consider going drogueless and instead popping a suitably sized chute with your main event.

Re: Right angle push button switch relay?

Thanks for all the replies. I've probably jumped the gun a bit here, I reckon I'll be better off doing some bench tests regarding power consumption (both idling and recording) before I start looking at fancier switching methods. CATO, thanks for the link. I think I had ignored the GoPro remote for g...

Re: Full Clip - 54mm MD build

Just a quick update, I posted on TRF regarding the Top Flight X-Type chutes and what speeds they can withstand. Preston Noble, the proprietor of Top Flight LLC, chimed in on the thread and it looks like I'll be getting him to make me two 10" Ultra X-Types.

Right angle push button switch relay?

Hi all, I'm not even sure if the above makes sense, and I'm taking literally the "I could use that" section of the forum. So please bear with me. I'm wondering if there's some type of device out there that effectively provides me with a right angle button depressing action in a small form ...
