With the ailerons now being reduced in cord you may find that you have inadvertently increased the negative incidence angle of the wing, (it points downwards at the front), and this negates or reduces lift when trying to maintain flight. You may need to place a shim or 2 under the wing LE so that the plane will fly if at all. If necessary you could always extend the ailerons and even the wing tips to obtain greater wing area!
Reduced cord? No, the ailerons were just cut off to reattach with real pinned hinges. This plastic sheeting would never work as a flexible hinge like paper and hot glue does. The wings are fully the same size as the plans show.
The turning or doing donuts could be simply the wheels binding on the axles or a "P" factor issue. A large SF prop will reduce the "P" factor effects and so a straighter taxi will be easier. If it persists you may wish to consider adding some side thrust!
For the wheels, one thing I'll do is (silver) solder washers to the last bend to keep them from trying to ride up the gear. I'll also try making bottle cap and pool noodle wheels instead of foamboard and coffee straw (apparently too-soft bushing). How much thrust difference is there between the 9x4.5 and 10x4.5 props included with power pack B? What about going from 3S to 4S? How much prop and battery can it handle?
That's the point.

That foam probably isnt ideal for the flitetest build methods but it is pretty strong. Ived used similar before for home made designs that worked well. Might as well figure out how to build with what you got!
The main issue with FT build methods on this foamboard is that you don't want to bend it much without heat softening it first (hot glue or whatever), no test-fit bends. Also (as mentioned above) no flexible hinges, the plastic is too stiff and brittle. Use real pinned hinges instead, or tape or monokote hinges. Where gluing flat surfaces together, you may also want to rough it up like with servo sides to give the glue something more to grab onto.
One case where the increased weight shouldn't be a problem is if using this board to build boats.
