    Going tp use 5x5 or 5x4x3. Havent decided yet. They clear by about 3/8 inch. Could use 5.5 but I think they are too close if there is any flex.

    I did twins on the MK1 and it was very sketchy so we didn't offer it. Make sure cg it right on stock. Too far back and be prepared to duck! Don't ask....
    Good luck Thunderfisst!

    I don't think that'll be a problem especially since the airfoil wing doesn't need much airflow to provide lift. As long as you are able to get a 1:1 thrust to weight ratio you should be ok. The thrust angle on the motors will be critical though.

    I've put thrust angle as close to 2 degrees as I can and they are perfectly parallel with each other. I'll give it a thrust test before I glue the cowls on.

    Ahh, heck.....just put a 12V car battery up front. May need it for proper CG with 2 motors. :0

    Seriously though....nice work. Cant wait to see how this comes out. From my experience so far with this airframe, mount everything as far forward as possible. Use long control linkages if needed, ESCs under the battery compartment maybe, and heavy glue (Hot glue) forward of CG and light glue (CA or Foam Tac) behind CG.

    Good Luck!

    Agree with you Slobberknocker, and to builders of this plane, we recommend 2200-3000 3s up front. The 3000 actually feels good, so definitely don't skimp on the battery. After all, this plane is designed to carry a VW beetle on the nose.

    I saw this one last father's day on a flat bed. It was being transported to an air museum on long Island, NY. The rotary canon was still in there, but it was decommissioned.

    Everything is all together now and CG is right on with batteries in middle of the tray, plenty of room to go either way. Just thinking the smaller batteries for lighter weight for maiden. I'll check thrust and may do the 4s.

    with counter-rotating props should the tips be rotating towards each other on top or away from each other. My first twin.

    Typically towards each other on top but really doesn't matter. I run them which ever way sounds better.
