Congratulations on the record. Is that the NZRA, Taupiri launch site on Kneebone Road?

 

[boomtube]

Kind of a long way to go to get a “Sugar high”.

 

[Fuse Eh!]

SWEET!!!

Sorry, couldn't resist. Congratulations on a truly spectacular record flight!

Wow! That thing lit off and just disappeared!

Excellent flight and congratulations!

This record was set by Phil Vukovich from New zealand. Other than this video and a photo on NZRA website (https://www.nzrocketry.org.nz/index.php?page=workshops-2) I couldn't find any additional information about this flight. Since it only mentions one 125mm motor and that the second stage has unusually small diameter I believe that this is actually a boosted dart, but can't be 100% sure. If I remember correctly there is a few guys from New zealand on this forum. Maybe they can provide some additional information. It's really a shame that a lot of times such cool projects are so poorly documented.

The sustainer was powered (sugar), not boosted dart. One can imagine the extra altitude potential with a higher performance AP motor?

Ill ask Phil if he remembers his password to TRF and he can add some more info if he likes, Here is an interview the media had with Phil the day after the launch. https://www.3news.co.nz/Sugar-fuell...ecord/tabid/423/articleID/321703/Default.aspx

Thanks for this info Chris. Do you maybe know what was the second stage diameter?

 

[K'Tesh]

That was a nice video...

I'd never seen a rocket land back at the pad and suck back in its smoke before

But Seriously... Congrats on the flight!

Congratulations on the record. Is that the NZRA, Taupiri launch site on Kneebone Road?

yes, have you been there?

 

[phil1]

Thanks for this info Chris. Do you maybe know what was the second stage diameter?

40mm. 400gram propellant. top speed was 2700kph. I have plans to get more altitude out of it by ignighting the second stage earlier

 

[chris m]

So the second stage had a retractable fin can ? It looked like I single stage

 

[Andre]

Phil what kind of electronics did you use for staging and for tracking? Was the 2nd stage motor ignited with a head-end igniter or did you run the wires through the nozzle? How was the recovery setup? Did you have some kind of dual deployment in the second stage or just a single small chute?

 

[Threemorewishes]

yes, have you been there?

Yes, back in March 2013 I was in New Zealand on a holiday where I met up with Evan More and a bunch of the other very friendly club members for one of their monthly launches. We had a very nice visit with a very friendly group of rocketeers. I would recommend that everyone who has the same opportunity not pass it up.
