  1. A Rugged rocket

    Posted by Unknown on 10th Oct 2017

    When I received this rocket I was not sure how it went together. I found some old instructions on line and found out that I had an extra piece that did not belong and was minus the switch band and one other item that was to short. I contact Madcow and they were prompt at sending me the correct parts for free and said to keep the extra part at no charge. At first I was going to give them 3 stars , but gave them 4 for the prompt correction of the order along with the performance. The first flight (Used an L1000) prematurely separated part way up because I forgot to drill vent holes. Surprisingly there was not to much damage after the crash. I was able to repair it with ease and launch it again with success using an Aerotech K850 Dark Matter motor. It flew to 4000' out at HellFire 22 on the Bonneville Salt Flats.

  2. This is my favorite rocket

    Posted by DavieRockets on 29th Jun 2016

    Of all the high power rockets I have built, this is my favorite. It's impressively big and I like the 5.5" to 4" transition. It's not just another 3FNC rocket. I converted this to a 75mm motor mount and it flies great on L and M motors. Try the L645 green motor from CTI. You, ll get 8000 feet out of it. Nice green and black fiberglass parts and nicely shaped fins. You get a lot of rocket for your money.
