Most of the configurations do not have a central keel to hold for launching the plane.
For an easier take off we recommend that you use another person to launch for you.
With the side by side configurations, hold the plane by the wing tips with both hands, and push it slowly forward.
For Top-Bottom configurations hold the plane by the upper module.
The big wings or the double planes have a lot of lift, but also a lot of drag. Expect slower speeds than the single plane version.
The big wing, and the double keel creates a momentum to increase the dihedral angle too much. To avoid that effect, put a stabilizer underneath the rods. Even a popsicle stick is effective.
Flying is windy conditions
Having double motors allows us to use heavier paper (up to 110 GSM). The bigger wing area, the high thrust and the stability of the plane, makes it easier to fly even in windy conditions.
