I managed to fit the drop tanks and check AoA.
When plane turned off, AoA is just above 1°. When plane turned on (nose Wheel jacked up) AoA is 2°.
It should be enough for easy take off.
I will not fly the A4 with drop tanks as ground clearance seems pretty small...
I also test ran the engine OK (Wren supersport).
