Compatibility & Build Notes
Build note 01
This airframe sits in the 2.5-inch class, which sets the overall build scale and prop envelope.
Build note 02
Treat 2.5 inches as the practical prop ceiling when pairing motors and props for this frame.
Build note 03
cinewhoop positioning gives a quick clue about the intended flying style and parts profile.
Build note 04
Internal stack clearance is limited to about 25 mm, so taller electronics should be checked carefully.
