About this product

The iFlight ProTek35 3.5" 4S HD is now equipped with the Caddx Polar Vista Digital HD System!

After the very popular 3-inch Cinematic EVA bumper BumbleBee and Green Hornet CineWhoop series release, iFlight continue to strive to increase performance by coming up with their master Protek series. iFlight was able to increase the speed and thrust by 50% compared to its 3-inch predecessor which gives a lot more room for a lot more fun; as a result, the ProTek35 is equipped with 2203.5 motors, Beast F7 AIO Flight Controller, 45A 2-6S ESC, and the Nazgul 3535 propellers. The Protek CineWhoop has a longer flight experience and weighs less than the previous cinewhoops! 

Our all-new 3.5inch project is finally ready for all you content creators or those guys who like to wear some protection every now and then. Prop protection is what we're talking about here... Durable plastic protectors with copper standoffs, portable compact design, easily accessible UBS port without disassembly, LED battery status, lost model buzzer, and a universal GoPro TPU for a full size or naked GoPro. If you wanna go extra light, get one of our 5V balance plug GoPro power cables to get rid of the internal battery.

ProTek is not necessarily just a Cinewhoop series but far more. Equipped with our all-new 2203.5 motors for more power and less heat. We were able to increase speed and a lot of thought was put into the different assembly options. Our stock BNF will ship in the standard configuration but you can either do a pusher mode (flip the building upside down) or a lite mod (remove the protective plastic for weight optimization).hrust by 50% compared to its 3inch predecessor which gives a lot more room for a lot more fun. Our GPS measured maximum speed was above 120km/h and a maximum thrust of 750g per motor (3kg in total) would even carry heavier cams than a Gopro but also do some loaded punch-outs or light freestyle moves.

Note: Battery, GoPro, and GoPro mount NOT included.

Controller Compatibility

The DJI Remote Controller is recommended for beginners since you won't need to set up another receiver, but it is also optional in this BNF drone because it is NOT required in order to use the FPV system. If you don't choose to use the DJI Remote Controller, you can choose a receiver option for your transmitter and then bind to your own radio as usual.

Our current frsky receivers default version in 2.XX requires us to use the same version of the frsky transmitter.

If you have no frsky transmitter, please downgrade the version lower than 2.X.X, www.frsky-rc.com for more details.
