    Heehee...I was tempted to go completely "fly by wire" but the thought of having an electrical glitch scares me...if the electronics decide to open the throttle full and hold it there I would be scared!!



    The choke is not really that dangerous so im not worried about using electronics for this..



    But yes, in the future its something I want to work on..get a reliable aircraft style fly by wire system which possibly has an auto stabalisation system...

    i recorded Mythbusters last night as they attempted to prove that successfully building a "jet pack" from plans off the internet is a busted Myth. I might try and edit as much as i can and place it on my video page soon, the program involved making two ducts from foam and kevlar/glass , vacuum bagging and other bits that also are part of hovercraft techniques. I found it interesting, especially when at one stage of my life i was continplating building a similar item. (i wont be now after watching that though hehe)

    I worked on a jet pack a few years back - we called it the flying rucksac. Consisted of a small turbojet strapped to a burly and slightly bonkers gentlemen. Just about flew... but the engine life was about 20 minutes!

    The one that was on mythbusters last night used a rotax 503 and never flew either. I have seen a doco on one built by NASA but cant recall the height it got to, it was high enough to go over large hills though from memory. Stability would be my first concern so for my next project maybe i'll do a hoverboard instead

    It must be possible because choppie, a small homebuild hellicopter uses the same engine and it works fine, plans also available on line, my dad wanted to build one. Those jet pack guys just need to sort out a few things like lift



    maybe put bigger fans on as well as changing the ratio a bit.



    Not for me anyway.

    Dunc,



    why over engineer?? all your doing is adding more systems to a known vairiable.



    its a basic choke system, if you had injection fueling, i would think thats pretty good, as injection engines use a 3D map to control fuel air ratios, and do similar to give a rich mixture for starting.



    lets be honest a simple manual choke for starting and flipped off prior to moving off is all that you need.



    have you heard of the KIS method?? Keep It Simple.

    Yeah, I could have kept it simple, but I wanted to try something new....



    IMHO this is simpler than using a control cable, but thats just me...



    We will see how well it works...

    Why not just get an automatic choke from an older car? It is just a piece of bimetallic spring and a rod. This would save you having to run a cable. Once they are adjusted properly, they work fine forever.

    Any ideas what I can use as a choke lever for my craft?
