    Jet powered Q1

    Elliot Seguin of Wasabi Air Racing is definitely a man after my own heart. He put 2 X 85lbf jet engines onto a Quickie Q1. https://youtu.be/x_keYAFcsXU https://youtu.be/CMme-EwQgZ4

    Turbine engine discussion

    In order to reduce the hijacking of Acrojets F16 thread which is about his aircraft, rather than the powerplant, I've started this thread to carry on the discussion about turbine engines as there appears to be keen interest in the subject. I'll start by adding to the discussion about turbofan...

    Orion's race plane design "Gumbo"

    Our dear colleague Orion (Bill Husa) was working on a race plane at the time of his passing. He had nicknamed it "Gumbo" and I had the privilege of Bill showing me over it when I visited his facility a few years back. I was surfing Barnstormers (as we diehard enthusiasts do) and found an...

    Rotax 912 firewall mount for Lightning Bug

    We are trying to optimise the space in the engine bay of the Lightning Bug which at the moment is very crowded. The Rotax 912 that we have fitted recently is using a bed mount with the attach points on the centre structural keel. We are looking at whether a firewall mount might give us more...

    Advice needed to stiffen a spring gear

    I would appreciate some advice from my learned colleagues on the forum about how to stiffen a spring nosegear. The Lightning Bug has a retractable nosewheel which utilises an aluminium leg. It consists of a slightly curved 4" wide and approximately 1/2" thick piece of stock as can be seen in...

    Lightning Bug engine runs

    We've finally completed the Rotax 912ULS installation into the Lightning Bug to replace the original 2 stroke AMW808. The first series of runs with the new engine have been completed and all Ts and Ps remained within limits. The first post-restoration/modification test flight is now imminent...

    Rotax 912ULS fuel system question

    We are installing a Rotax 912ULS into our Lightning Bug and we note that in the Rotax installation manual that between the fuel pump and the carbies is a fuel manifold that splits the single fuel line into two which go to the individual carbies. This manifold also has a fitting for a fuel...

    Single seat aircraft - what is the appeal?

    I am cutting and pasting a post from another thread as I feel this topic deserves its own thread. I'm not sure if I can quote from another thread here, but I'll give it a go. John Monnet sold over 100 of his single seat Onex kits in its first year of release. The Onex, in my opinion, has...

    Lightning Bug rebuild

    Background to the project: Back in 1991, Nick Jones followed on from his 4 seat speedster White Lightning kit aircraft with a single seat speedster called the Lightning Bug. It created a buzz at the time due to its exceptional performance, achieving (allegedly) over 200 knots with it's 90hp...

    Airdrome Aeroplanes 75% Fokker Dr1

    As if I don't have enough on my plate (Komet jet build in Australia and Lightning Bug rebuild in the US), I've now started an Airdrome Aeroplanes 75% Fokker Dr1 triplane here in the desert of the Middle East to help pass the time here. I am building the aircraft in partnership with a fellow...

    Rotax 912 custom radiator needed

    The Rotax radiator supplied with our used Rotax 912ULS will not fit into our Lightning Bug engine bay. It has a core size of approximately 13 3/8" by 5". Ideally, we would like one with core dimensions of around 10"x7". Could anyone point me in the direction of where (in the US) I could get a...

    Help needed - Autocad file conversion

    I'm not sure if this is the correct area to post this request... I have sent a drawing in Autocad (.dwg) format to two shops to have the component quoted but they both indicated that they need the file to be in preferably .stp or otherwise .igs format. This is definitely not my area of...
