Estes Big Daddy - Upgraded Print E-mail
Tuesday, 11 September 2012 12:03

I really love the Estes Big Daddy. It's a great kit - looks good and flys well on D and E size motors. My last Big Daddy had a number of flights on the Aerotech E18 reload & looked fantastic with it's big white flame. It's part of my regular fleet, despite suffering a CATO when the rear closure of the motor blew out.

At Christmas time, I picked up another Big Daddy kit on Ebay with the aim of converting it to fly on 29mm motors - the H128 specifically!

The kit sat, taunting me for months but I've now completed my upgrade!! This is the Really Big Daddy!

I started by re-cutting the centering rings and fins in 3mm plywood - the fins are very slightly larger than original. The launch lug has been swapped for rail buttons and I have also added 120g of lead shot in the tip of the nose cone.

Rocksim predicts that this will fly to around 2800' on a H128 or about 2000' on a G64. I'm looking forward to launching this!

TRAAU 24th June 2012 Print E-mail

The June launch was the first Tripoli Victoria launch I have been able to attend this year. Building Mission Control and getting ready for the trip to Perth (For the Williams launch) had kept me busy.

The June launch was a two-day affair, I was only able to attend on Sunday.

The launch didn't get underway until about 11am due to cloud cover which plagued us on and off all day; And it was cold. Not just regular cold - brass monkey cold!

This was a big certification weekend with several Level 1 and 2 flights and one huge level 3 launch!

Karl successfully launched and recovered his rocket to achieve L3 certification!

I launched my upscale Ballistic Chicken Insanity on a G64 and my Der Red MicroMax

Despite the cold and the patchy cloud cover, the launch was a great sucess and as always a lot of fun to attend.

Level 2 Certification (Finally!) Print E-mail
Monday, 02 July 2012 20:52

Last year I attempted my Level 2 certification flight with my big rocket, Freefall. Unfortunately, it sustained some damage on the nose cone from impacting on the back of the rocket (the parachute got caught up on the camera I had strapped to the side) and I didn't get my Level 2.

With the trip to Perth recently, I decided to try again! This time I was successful :)

I lauched a 3.9" Loc V2 with some added nose weight on a J420R. It was a fantastic flight and really happy to have my L2 cert now, too!!

Big thanks to Scoop, Kopius and everyone else who lent a hand on the day!

To Williams and Back in 15 days. Print E-mail

This year I took the opportunity to do something big - drive from one side of Australia to the other and back, a round-trip of a little over 7900km (4900mi). The great Aussie road-trip!

The main purpose of the trip was to attend the Williams "Wildfire" Westernationals event near Perth, Western Australia. Organised and hosted by the good folk at Tripoli Western Australia for the past 3 years, with 2012 being the 4th.

I've uploaded photos of the trip to Flickr

Along the way, stops were made at Woomera, The Great Australian Bight, the Perth Zoo and Wave Rock as well as crossing the Nullarbor Plain. Check out the full set of photos (broken up by each day) here.

Despite being eliminated from the iiNet TopGeek competition during round 2, I did get a story in the Dandenong Leader newspaper!

The email I received from iiNet said that I only missed out winning my category (Tech) by a few points, coming runner up. Oh well! I'll try again next year!!

ImageiiNet, an Australian Internet provider, has been running the TopGeek competition for a few weeks now. I figured I would enter and see how far I could get. Round 1 is now over and thanks to quite a few friends I got enough votes. I have made it into Round 2 - I'm now in the top 50!

Round 1 was all about votes. Round 2, however, is about creativity. The task for me, being in the Tech category, was to invent something. Naturally enough, I invented a rocket!

Here's my video submission -

I invented the GEEK rocket :)

You can download the RockSim file from Here. I also had to provide supporting documentation for my invention. I have packaged that up as a PDF file and you can read it Here. (I'm using to host the files, any problems drop me an email)
