S2P

After successful experience with the S1, SAMAD Aerospace (SAL) progressed to a larger prototype with a wingspan of 20% size the e-Starling, the S2. This aircraft was also fully electrically powered and remotely piloted and was used to demonstrate a more scalable prototype.

The S1P uses contrarotating propellers to generate lift, instead of high RPM electric ducted fans (EDF) of the S2P.
