It would help if you describe what the 4 kg of thrust is for and how it is to be used in VTOL For instance one motor or many?
All VTOL requires specific control and stability features that...

The AN 2 undercarriage is supported by a stub centre section of the lower wing which is braced by a strut to a specific fuselage former. It was obvious to simply include this in the former printing....

Jools
In a turn as you describe the rudder creates yaw (which is not a turn) and you are relying on the wing dihedral to cause the bank that actually creates the constant turn. Until such time as...

My own view is that it is not ailerons that is the issue but the rudder.
You do not steer a plane in flight with the rudder but only use it to apply a 'correction'. From the ground it is difficult...

It is a good idea to extract and tape off one of the red pins as shown in the earlier post. It means it is then simple to re use the ESC in a single engine job later if the worst...

dasintex
No its the other way round.
kV means the motor revs per volt applied so a 950 kV motor will turn off load at battery volts x 950. For example with a 3s LiPo that would be 11.1 x 950 =...

Of course the full size had no dihedral at all. Its 'tip to tip' box spars were built in one piece.

Certainly adding a servo is a useful way to add ballast but shortening the nose to account for the heavier motor would be a rather more efficient solution.
