    Second impression... 
    I’m re-naming it to the “Wow prop”... Going from a too small warp drive I have gained 700-1000 RPM on my regular cruise speed and 20+ km/h on maximum speed... As I’m not looking to fly much faster it will be interesting to compare the fuel consumption - but I need more than the 1,5 hours I got today...

    Bye-bye Warp Drive...!
    I just had the time for a very short test flight after mounting the prop and doing some initial adjustements - I still need to increase the pitch slightly. So no performance feedback, just a very first impression. Runs very smooth (and as the warp drive is already a smooth prop..) and it is noticeably quiet. I guess that is the swiped tips compared to warp drives straight cut tips... I hopefully have more to share after the weekend.
    It is a mean looking prop...

    I honestly don't recall how I did it... but take a piece of wood, drill 2 perpendicular holes with the diameter of the pins at the required distance and use it as a jigg is what I would do today... once the pins are in place put the tubes on them and use that half of the cowling as jigg... don't forget to put 2  sheets of thin plastic between or they will be glued forever...

    I think I used Plastic Padding (I am Swedish after all... even if it is nowadays owned by loctite) but anything that works with the glass fiber cowling and get stiff enough would do the trick.

    I never liked the original system here you have to bend the cowling when closing it. My solution was to cement a metal pin and a corresponding metal tube on the 2 halves of the cowling, one set on each side obviously...

    It works great and provide a very good positioning when closing the cowling. As long as I stay subsonic ther is no tendency for the cowl to "gap"

    I can confirm this is correct, the final diameter depend on the number of blades, i.e. in the hub

    My Scimitar SL107 3-blades arrived today. It looks great, can't wait to try it! Very sexy prop!
    It took longer than expected... there is a monetary embargo for Europe on Ukraine so my bank rejected my initial transfer. And as my bank appears to be incompetent they didn't know why the transfer, done on the web, was rejected and pretended I had used an incorrect account number... With Roman we found a solution - and my bank messed up again (did I say there were incompetent?). Well, we got that straighten out and now the prop is here.
    I'll keep you updated on my prop experience but it might take a few days.

    Or two friends so you can have a beer while they take the pain of changing the bungees...

    Hi Turbo,
    I'm not familiar with "type-1 bungees from AS&S", the one normally recommended to use (i.e. the one used in the original design) can be found at Aircraft Spruce with reference 06-12400 (3/8" shock cord) 

    I made an attempt with a "not so stiff "bungee with the same diameter from a marine store... flexed well by me just sitting down in the plane... A less stiff cord would need additional wraps and there isn't much place for that...  I assume you could use a different quality bungee but the length and/or number of wraps would need to be adjusted accordingly.  
    We need to find a better solution...

  11. FredStork added a post in a topic L.G. bungee blues   

    this is one of the areas where I admit poor design of the Avid Flyer... 
    The good solution is to install the kind of gear Trent Palmer has but as any ideal solution it is expensive...
    My recommendation is to  REMOVE the merciless safety cable to avoid having it cut the seat struss in 2 and replace it by a tight bungee between right and left leg. I know, incomprehensible as explanation so here is a picture. You can use any heavy duty bungee cord, the stiffer the better actually. In the beginning of the deflection (ie normal landing) there  will be little tention on the horisontal bungee. Only at bad landings, great deflection, will the bungee enter in action (and save both prop and seat struss).

  12. FredStork added a post in a topic 1st flt Avid - impressions   

    So how do they say this... If it ain't broke, don't fix it...?
    Not all planes are alike. The Avid Flyer takes a lot of footwork and some getting used to but it has a very sane behaviour. While no one will say it is the easiest plane to fly with clean turns there are no real traps to fall into. 
    But it takes a little time to fully appreciate (well, that was actually very fast) and master (takes a little longer).
    Get some airtime before deciding what to change, if not you might not improve your plane but degrade it. By degrading I could mean just that (depending of what you used to fly before...) or change characteristics of the plane that you with more experience would have appreciated (or no longer noticed).
    I changed to the the F7A bell cranks, they have a positive impact but do not transform the plane (it still need an active pilot - luckily as that is one thing I like about it...). With just the F7A mod you do not have to disconnect anything when folding the wings.

    Hi Randy! 
    I don't say this is the problem but I noticed a difference between your and my setup. Compare your second last photo with this one:

    So true... talking from first hand experience - I had an MGB with a Lucas ignition system a very long time ago...
