Big Egg, Big Thrust
6.11.11: It’s has been a while since I last updated the blog and there is much to mention. The original Loncin gx200 engine now has a new home in a larger stainless steel frame together with a Bailey-Egg reduction kit and a 1.3m prop from D&T Propellers. This machine was originally built for a BIG challenge but due to financial constraints the ‘challenge’ has been abandoned for the foreseeable future. I did initially try a smaller alloy framed design to utilize the redundant fan blade assembly from the defunct Eggmonster project but I was unhappy with the strength and quality of my ‘Durafix’ joints. So I invested in some 16mm stainless steel and made a tube bender to roll the cage sections.

Now we have the same thrust of the old Eggmonster but for much less weight. With our bathroom scales we achieved 48-50kg (106-110lb) thrust this afternoon. A few minor niggles to sort out and we will be ready for our maiden test flight.
