Started prepping the Velociraptor R for what is likely the final flight of the year at Serpentine on the 9th September. Crops getting up and fire season approaching.:(

I guess it'll go like a cut cat with the L935 up its kilt :). No VTS this time as I still haven't managed time to analyse the previous flight data.

Are you planning to come to Thunda in April?
 
OverTheTop said:
Yep. Going to fly the half-scale Nike Apache. Hopefully crack 50k'.

Should be a fun few days!

I trying to figure out logistics and budgets now.

I originally thought the whole clan might like to come along, but the girls are a little less than enthusiastic for 3-4 days of just rockets, and my 9yo son gets bored at club launches after he’s flown his own.

I’m thinking I might head up with just my 13yo son and am looking at camping or a motor home rental...
 
Just worked more on my payload rocket Hurricane A, nothing special... Just your regular old D/E motor payload rocket...
 
Driving 1318 miles in a 30-year-old Oldsmobuick Family Truckster, no A/C, no cruise control / 4 hours of fondling a Nike Hercules = totally worth it!

I'll fill in more about the trip in my Nike Hercules CAD build thread after I recuperate.
 
Launched a 38 mm 4 grain KNSB motor in a Loki 38-240 case and an upgraded Art Applewhite Stealth. Not the most powerful, but probably my favorite motor I’ve ever flown.
 
Arrived home from a very productive and very busy launch. Now to go through and edit over 1400 photos!

Since I didnt post at the launch, I made several personal firsts, and set several new personal bests... I flew my first 54mm motor, my first K, and broke the mile barrier for the first time. I also broke my personal best for altitude 4 times, with each time pushing it higher, ending at 6,793ft.
 
Took delivery of my $60 gumtree find (AU equiv of craigslist)... if I’d ordered it from apogee and paid shipping, it would have been $285 minimum...

2.6” MadCow Black Brandt II.

The MMT had the two CRs glued on, and in the wrong place, so I was starting to think I’d have to order replacements - the seller included the glue he used, which wasn’t epoxy and that I’d never heard of - and hadn’t scuffed the FG at all.

Two minutes of poking later later, the CRs popped off, the glue peeled and I’ve got a clean kit again...

Kinda makes me glad he didn’t turn up to the local club to fly this as he was building it... [emoji12]

Feel like expanding as to why it’s your favourite?

Because I made it from scratch! I’ve been making smaller versions for years, but this is the first time I had upscaled it to something substantial. I was probably more nervous for this than for my L2 cert last year.
 
This past weekend we here in New Brunswick had our big annual high-power launch! Witnessed a 2-stage N to M rocket that went to around 40k feet, which was insane! I also set a new personal altitude record.

Also edited and uploaded this video of the launch event to YouTube:

 
Passed my L2 written exam... now to test fly then cert fly this puppy... oh, and get my explosives license.

What do you expect to learn from the test flight?

Not trying to be provocative, I am really asking.

I've run through the risk/reward on the L2 flight a couple of times. I've concluded that, for the rocket I plan to launch, a test flight on an H that can lift it will not be safer for the people at the launch, or for the rocket, than the cert. attempt. Neither is it likely that damage severe enough to disqualify the cert. attempt will be field-repairable. Since I don't plan to have another L2-capapble rocket ready to go, burning my cert. allowance motor on the maiden flight won't be an opportunity cost.

FWIW, I wish that I hadn't bothered to test the L1 rocket(s)

My first-choice L1 rocket would certainly have passed as flyable after its test flight on a S/U G, but I didn't want to trust the singed shock cord (scrounged from an Estes PSII kit) for the high-stakes of the the L1 attempt -- so I put it aside and "tested" the Plan B back-up rocket. That one, on a S/U G80, had an ejection failure and disappeared over the hill.
 
hopped online and ordered a Nike XII in between patients in the ER from Mach1 rocketry =) The rest of the day sucks... but hey I got a rocket!

For me, the goal of this bird is to learn DD and to be able to watch the recovery chain unfold from the ground with the naked eye. That’s why it’s a 4” with a 38mm not a 54mm MMT.

Being able to L2 with it is just a bonus and not at all necessary.

Got it. Thanks. Yeah, I am with you. If I didn't want the L2 so I could take a turn as RSO, I'd probably skip. Much more interested in building than getting the rocket higher or faster. I just looked online, and it appears -- on a brief and slightly beery examination (its a beer & barbecue holiday in the US) -- as if there is a separate certification for RSO through AMRS? I tried to drill a little deeper to see if a flier's cert was required for RSO/LCO but...beer.
 
Found a hoby store in Rochster with rocket motors. Picked up some C6s for my Apogee Slo-Mo. (Then went to Dinosaur Barbeque. Afer living for 4 years in South Carolima, then driving for a sight-seeing ten days from Jacksonville, FL to Santa Monica, CA, the best "sothern barbeque" I have ever had is in Rochester, NY.)
 
I finally did some more research over the holiday (It's been over a year since the last effort) on the major components for a flight computer/GPS tracker system I've been working on.

Components/Sensors:
µProc: Teensy 3.6 (Purchased)
GPS: U-Blox NEO-M8N
Accel: Kionix KX220-1072 (Purchased)
IMU: Bosch BNO055
Pressure/Temp: TE MS5607-02BA03
Radio: XBee-Pro 900HP

The only part I'm hard set on using is the Teensy.
I may start a thread for hashing out the particulars with suggestions/critiques but that will be a long long road.

Don’t get me wrong, I *do* want to L2, but that’s not the driver for this bird.
