    Re: My First Scratch build

    Finally home long enough to open the mold... I have a fuselage!! Very happy with the results.

    Weight so far...
    2 wings...1273
    2 Horizontal stabs..654
    Fuse..2155
    Total...4082 grams or 9 lbs

    Still have to include the vertical stab,wing tips and ailerons..so possibly under 12 lbs. Much lighter than I expected. I was figuring about 15 lbs. The wings will be made much lighter in the future as I have redesigned my method for holding the wings on.

    Re: My First Scratch build

    Noticed a couple of problems. One not so big..but the other will take a bit of time.

    A closer look at the fuse shows a slight misalignment. Good enough for the prototype but not production. That has been fixed with the addition of some 3/4" frames to stop the top mold from twisting. The other is more complicated. I chose the wrong location for the elevator tube and this means re working the molds. Not the end of the world..but a set back for sure. The tube needs to be further forward to place the load over the vertical former for structural strength. Oh Well.. no one said it was easy

    I glued the lower halfs together. I'm impressed with how light it is but yet super strong.

    Yeah that honeycomb is great for panel stability and super light , I see your using carbon fiber in the more critical areas to prevent fractures ,good job ..

    Re: My First Scratch build

    Cheers Roger

    Got a lot done today. Modified the molds for the new spar location, layed up a new rudder with the honey comb material, laid up a canopy and most difficult of all figured out the formers for the spar. The electric version is easy with a solid tube receiver and tube going right across the engine pod, but the turbine version is cut into 2 pieces to allow for the pipe to pass. I will be using the turbine version for proof of concept.

    Things to do...
    Make hatch
    Finish engine pod formers/engine mount
    Relocate spar location in Horizontal stabs.
    Glue on wing tips.

    Are you ready for this....
    ASSEMBLE PLANE!!
