Cheerson CX-91B features

Few months after the first release of the CX-91, the first 250mm racer from Cheerson, here is a new revision/updated version, the Cheerson CX-91B with stronger FET and some improved minor details. More with the B version (versus the A), some Goggles are added but they must be used with the 4.3″ FPV monitor via the AVout.

Frame: The Cheerson CX-91B still comes with a full nylon plastic body. Any sign of 3K carbon element, from main structure, arms and landing gear. Versus the first edition, no real visible difference: the same clipsable canopy, etc… except maybe now the presence of a CloverLeaf antenna instead of a basic linear model. No more polarization mistmatch… A good news for the FPV range.

LEDs: There are 2 white LEDs to keep orientation for FPV flight but not strong enough for confortable night flights.

Weight: It’s weight is 421g with battery.

Propellers: Cx-91b uses triblades inspired by Bebop. You will need the special wrench to install/remove them.

Battery: a strong 1600mAh 3S LiPo with a discharge rate of 30C !!! Not bad at all

Camera: CMOS cam with a lens offering 120deg of Field of View

FPV monitor:4.3″ FPV monitor including a sunshade. The brightness is excellent, no problem to see even in strong daylights. It’s a FXT model.

Goggles: The goggles bundle with a compact transportation casing. The facial foam reject most of daylight rays. The immesion feeling is good. The quality is pretty good with a good brightness. Sure don’t expect VGA resolution per eye but it’s more a QVGA resolution. The good news, we can fly with them without too much problem. A good positive surprize.

Video transmitter: 5.8G 40CH video transmitter with SMA connector
