Downloading the plans


Thank you to those that have donated, it's appreciated



Craft was started Mid October 2004, and i achieved my first test hover in one spot on 11th November 2005. The plans were purchased from ASV Australia and i have stuck to the plans up until the stage of mounting a duct, from that point onwards i'm working off the top of my head which could be classed as a scary thought.

So the main items i'm not sticking with in the plans are , Duct, rudders, length, width, steering, fan assembly and the motor


Please note that although i do compress the original pictures, this web site is best viewed with FireFox 1.5+ and Broadband


In order to be sure my site is user friendly i'd appreciate it if you take a quick trip to my Online Poll page and answer the poll on internet speeds. It will take you all of 5 seconds to do and i can then get a idea of what the majority internet connection speeds visitors to my site have and then i can adjust pictures and video's to suit.

thanks Lazza


Latest News : updated on October 29, 2008


Added a FAQ / buyers guide page which is yet to be finished but will add pictures etc as they are availible


Well now that i've been there and done that as far as the hovercraft goes i've decided i need another project. So the hovercraft site is now going to have another area to it devoted to my new project


I went through a moment this month where i got bored at nights so i decided to play with a new gadget i just bought called a MS6115 mains LCD power meter. It measures household electricty usage and out of curiosity i thought i'd check if my monthly power bill was justified. I added my findings to the web just in case someone else went through the same moment of boredom and was wondering how to fill in time hehe. I used to laugh at people that turned things off at the wall cause i just thought they were being tight, but in actual fact i now know it can actually make a bit of a difference. the page with some of my readings is found here


June 22 2007 - Just added a "winter in Alex" section just coz i can



NOTE: Only the last three recent updates will be listed here. Past news can be seen here
