After our very popular 3-inch Cinematic EVA bumper BumbleBee and Green Hornet CineWhoop series, we were trying to increase performance and reduce weight for an even better and longer flight experience for a wide variety of use. 

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. 

ProTek is not necessarily just a Cinewhoop series but far more. Equipped with our all-new 2205 motors for more power and less heat. We were able to increase speed and thrust 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. 

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 mod (flip the build upside down) or a lite mod (remove the protective plastic for weight optimization).

Be sure to check out our Bind-n-Fly collection as well as all of our iFlight Products!

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