Re: Any dates for Westmar launch?

Hi all. Is there any news about a Westmar date? Just trying to plan leave dates with work etc as it's a 3 day drive each way for us. Cheers!

Re: Al Bychek passing

Wow, I didn't actually know this. I only met Al at both of the Thundas, but what a great guy he was. Such a shame, and a huge loss to all of us. :(

I've had an interesting couple of months. (pic heavy)

As a lot of you know, I'm currently studying an engineering degree at uni. I'm at the point where I need to complete my internships. I found out about research scholarships at ANU in Canberra and applied for a project working on high-altitude balloons. I figured I already have experience with flight...

Re: Thunda Down Under 2019 Photo and Video Thread

Matthew's RB-05A ... motor? M1830? Matthew's Dark Star ... motor? Hah, a bit late now but for posterity: Yes, Pro75 4G M1830-CS, and Pro38 6GXL J520-SK. Great photos and videos, everyone. Thanks for posting! I didn't get too many photos. Looking back at the silos and campsite after recovering the D...

Re: Need to buy or borrow a CTI l1395 or l1355 for a two stage flight.... that just maybe is crazy and well thought out

Lamp, you know, I flew an M1830 at the last Thunda* , but I don't recall whether it has the pyrodex or not. I'm fairly certain it was just an ematch and a smoke grain. It did light without issue. If you search youtube for "Matt's L3 cert flight" you'll find drew's video of it. I've flown a...

I have a 4G M1830 that I'm not married to. Would need a 3 or 4G 75mm that can safely launch a 6kg dry weight 4" rocket in it's place. :)

By the way, the phone number you gave apparently isn't yours...

Not telemetry, but for tracking I will have a couple of Eggfinders: 919MHz and 921MHz.

Another first for me - having to take a ladder to the launch so I can arm my avionics. :lol:

Re: Campsite map/choice for Thunda?

I'm keen to get this sorted, too. Will have two camper trailer setups in our group. I'll be on the road away from Internet access for a week prior (upgrading my dear old Mum's off-grid solar stuff in the middle of nowhere). Will be arriving at the Funny Farm on the Tuesday, so that I can help with r...

Re: Which AT 38/360 or 38/720 reloads for airstarts?

I would go with a CTI in the sustainer, the pyrodex slug in the top grain really makes them easy to light. If you really want to use an AT, as Kryten suggests, a Blur Thunder motor would be my choice... I really need to recheck what motors I ordered, but I'm fairly certain it will be a CTI in the s...

Re: What is your project for Thunda Down Under 2019?

Well, I -should- have something to fly. The 2 Stage Darkstar Jr and the RB-05A have made it to painting. I have also reincarnated my Drag Queen from Thunda15. It has a new airframe (the blue tube warped on the original after spending some time in a paddock before being recovered) so it is now dubbed...

Re: HobbyKing Mini 3-Axis CNC Milling Machine

Re: the first one you posted. I just made a control board for one at uni. We used a Freedom K22F mcu for the brains. I think the HK one uses an Arduino UNO. Range of motion for the head was ~150mm x 100mm x 40mm, iirc. You'll get less working room when you try to clamp down the work piece. 200 full ...
