Hello,
there are few reasons:
- it was always possible to mount it in normal way.
- the unit's CG in this position is not balanced for aileron axis which is approximately 3 times more prone to oscillations. So this can be reason for aileron oscillations and worsened performance.
- it would add at least next 8 mounting positions which mean even more troubles for the beginners (it is already uneasy to select correct position for some).
Is'nt it possible to move the unit little bit back so that Spektrum connectors are accessible?
What is actually reason to disconnect Spektrum satellites?
