You already knew the ProTek 25 in normal version. Here is now the pusher version. Both are very similar: they share the SucceX-D Whoop AIO v3 flight controller with a 20A 4-in-1 ESC, Xing 1404 brushless motors at 5500KV for 2.5 inch Nazgul Cine 2525 propellers, a Caddx Nebula Nano camera and a DJI Digital FPV System compatible Vista box. Protections surround the propellers for safer flights.
The structure is reversed to present the motors upside down. According to iFlight, this reduces the influence of the structure on the airflow, provides better range, reduces propwash and makes less noise. This will have to be verified: the previous pusher models I tried were noisier than the normal versions. But it ensures that you never see the propellers in the picture, even with an HD camera close to the horizontal.
The ProTek25 pusher is designed for 4S Lipos with an XT30 connector. It is capable, according to iFlight, to fly between 5 and 7 minutes with a 4S battery of 650 mAh, 6 to 8 with a 850 mAh. Equipped with a GoPro camera naked version, count on about 2 minutes of autonomy less. The weight of the device is under 250 grams with a 4S battery of 450 mAh and a GoPro 8 naked. It is offered in a version without a receiver, to be used with a DJI radio control or your own receiver, or pre-equipped with an XM+ or R-XSR receiver from FrSky, or Crossfire Nano RX from TBS.
