    Alright here is a thread just for the 20cc Edge profile. I will keep this first post updated with the important things we come across as people are building it.

    :fist_pump:Now here is a build to look forward to!

    I have questions too!! I should probably wait until I get the plans, but what can I say... I am excited!

    A parts list of some sort could be handy to put together:
    Do you have a good source for the carbon tube?
    What oz/in servos, 100? Speed recommendation target?
    Gear size, wire? or?

    62" wingspan
    55-1/2" length
    950 sq in of wing area
    Two piece wing using a 3/4" wing tube


    Thanks for sharing your plans, and letting us put together one as well! Very kind of you.

  5. Ugh. Been there done that. Worst time was when my oldest daughter had RSV when she was about 12 months old. Hope she gets better soon!

    Yeah Emma had RSV at 3 weeks old while still in the NICU. Wasn’t fun either.

    Thanks for opening up this thread and yes it is exciting, but remember it a hobby so look after the little girl first the rest will come later I am in NO rush just excited it has started.

    Same as Nick info on the 3/4 tube and sleeve.
    And the 0.605 tube for the fuselage.
    Also have to get in touch with @jtec/radiowave for a profile muffler for my O.S. 22GT That will exhaust downwards when the engine is at 90 degrees on the fuselage. My have make a drawing of the motor flange time will tell.

    As I have it designed the landing gear is to be made of aluminum flat stock but you can do wire gear if you prefer. Choices on the tube is all up to the builder. you can go with a cheap 5/8" aluminum tube if you want from lowes or home depot. Down side is in a hard dork it will bend and you will have to bend it back straight. You can go with carbon. plus is it will be super rigid but down side is in a hard dork it will probably shatter and break. or you can go with a fiberglass tube. they are the best of both worlds as they will bend a lot before breaking but go back to their normal state after the impact.

    On another down side, if you dork the wing enough to damage any of the afore mentioned tubes your gonna be rebuilding a wing.

    option 1 for a tube if going for carbon fiber. 16mm is just ever so slightly bigger than a 5/8" tube. You would have to adjust the slot in the motor mount ever so slightly. only adjust on the bottom of the slot as the top of the tube is already designed to have the wing tube phenolic in the fuse sit pretty much right on top of it.
    Also could easily get away with doing a 15mm tube just be sure its centered in the thickness of the fuse.

    Here is a where all the tubes came for mojo and primo kits back in the day. Sorry I had originally said .605 it should be .602
