Today we had a very impromptue LARF launch in the blistering heat.
The launch came about after Niall Oswald & Brian Best had mentioned wanting
to launch sometime in July at the last UKRA launch.
Fantastic day 25 degrees little to no wind highlights in no particular order
Chris Eilbeck 2stage I-540 to J330 with onboard video truly awsome
Brian Best Wiz ARD K1100 fantastic
Pete Davey's Tomahawk
Matt Ohare finally gettig L1
Ady Waters 3 flights 3 class records
many other great flights.
Thanks to everyone who came down to join us and make it an excellent day
Some pictures here more to follow when people email me them
Thanks for posting the pics Damian! Just to thank the guys who came for
a superb day. I finally got the weather order dialled in right ! :-)
I didn't see your flight, nor Richard's, Ady's other 2, or Pete's, but
leaving early was made worthwhile by a stunning NIN gig last night :-)
Here's to the next 'un, which *might* be my L3 flight :-)

Yes, some of the best conditions I've seen at Pete's Farm / the
Heckington site. To launch without the site being windy, and with only
an occasional light breeze, and beautiful blue sky, was great! Proof
that if the weather does not confound, the site is glorious!
Yes, Chris is a guru of onboard video on rockets, and succeeding in
launching a 2-stage video flight which went supersonic was most
excellent. The fact that there was little or no frame dropouts on the
video was very impressive. Everyone loved the video footage. The speed
it came off the pad was quite something. Faster than I expected, but
then again, the Cesaroni I-540 is quite a punchy motor.
Seconded. A K1100 in a large rocket is just as impressive as in small
diameter rockets. The slower ascent (comparatively though with a K1100)
means more time to see that gorrgeous exhaust plume!
Looking at the name of the rocket, did Brian use an ARRD for recovery ?
If he did, I wish I had taken a look.
Yes, nice finish on that rocket. The weight meant it was a more moderate
ascent speed, so plenty of time to watch the long burn Hypertek K-240
hybrid in action.
Yes, I was out to prove how fast a turnaround time you can have with a
hybrid, so the launches were on the Hypertek I-205 and I-222 (which
allowed me to reuse the grain). Total time from launch of first rocket
to touchdown of the second rocket was 2 hours, but an hour of that was
time spent recovering the rocket after the first launch, and walking
back to the UKRA HQ, and walking back up to the range head again :-)
So, I reckon on about an hour turnaround time including time spent
opening up the payload bay, downloading the data from the RDAS and
Perfectflite MiniAlt, then closing the payload bay and re-prepping. I
think future improvements would include integrating a download port into
the payload bay, so it doesn't need to be opened up, and that's about it.
Also, redundancy in avionics is your friend :-) 2 altimeters, 2 ejection
charges each.... sort of ensures the recovery will be fairly reliable :-)
Yes, good to see "The Master" launching at an event. As usual, he didn't
disappoint, the 2-stage recovery was flawless (he used an ALTACC and
flashbulbs I think), and the rocket, being almost 10 years old, still
looks in nigh on pristine condition. Amazing.
I missed that one. I was off prepping I think! Well done Matt!
3? Heck I only saw one of them. No wonder he has so many flights on the
UKRA records tables. He really goes for it! Good stuff!
I noticed you modestly missed out your own flight amongst others ? More
details please :-)
Yes, thank you very much to Pete Davy from Pete's Rockets for his
hospitality, and to all the fliers, who made it a really great launch. A
nice easy going, chilled (in style, not temperature!) day :-)
I flew my crayon on a H Classic (thanks for the case graham) was preet good
but not to straight for some unknown reason, though it was a bit sticky on
Chris tracked it to the horse place over the site but we couldn't see it.
We knocked on the door and the chap came out to talk to us (astro physisist
by trade has a cverry cool observitor in the garden) the rocket was in one
of his fields with pigs in so he got it back for me. The tube is a bit
dirty as it the shock cord and it's lost a fin. - This pigs had started to
eat it :-(
'Fraid I haven't. It'll be tomorrow evening, just haven't had a chance
This working lark is a shock after 9 months of student life! Still, it
pays the (rocketry) bills :)
I've got some OK photos, I'm not quite sure but the camera (being
Powershot A20 no. 2) seems to have been taking fewer photos at~3fps
before pegging out than before...
It was a great day, a really nice atmosphere and some good flights.
Chris 2-stage flight, Brian's K1100 and Graham's K240 flights really
stick in my mind. From launch-controller distance, the HyperTek K240
really could be felt through the ground :)
I'll email photos tomorrow.
Do you have, or can you get, higher resolution versions of those
images? Mike's camera looked pretty swanky, the images in the gallery
are quite small though.
Haven't had a chance to sort mine out yet...
