Top Features 🔥
Versatile Body
The Body is designed to carry small to large batteries for agile or long range missions
Smart XT60 & UBS-C Plug
The XT60 plug is located in the front to gain more space. With the USB-C plug you can directly power your GoPro/Action Cams
Front & Back GoPro Mount
The drone has a front and back GoPro mount which gives you more creative freedom. The 6inch allows you to easily carry both simultaneously
Efficiency & Agility
Reinforced H-frame for 6 inch to have the best of both worlds (agility & efficiency)
Optimized Motors & Props
The Motor is designed for 6inch to give both great performance and efficiency. The prop is specifically optimized for this drone
Reliability
BOB57 comes with a protective shell against hits, droplets and dust. It also has a high quality GPS and components for more reliability (spike absorber & extra capacitor)
More Facts
Reinforced H-Frame
BOB57 has an H-Frame. This gives you similar performance to a wide X with the advantage for less props in view. This H-Frame compared to competitors features a reinforced middle section to add extra stiffness which can be a weakness of these type of frames.
Optimized Props
These propeller was developed as part of a collaboration between Ellis van Jason and the leading Prop manufacturer Gemfan. It is optimized for BOB57 and brings max efficiency at 47% cruising speed which fits exactly to the Cinematic flying style of Ellis van Jason.
Signature Motor
This motor was specifically designed for 6-inch drones. The 1500kV give you enough power to do action based shots at high speed but also efficiency for long-range missions. When having 2 GoPros on you can feel the benefit of bigger props & motors.
Smart XT60 & USB-C
Compared to other FPV drones, the XT60 plus is located in the front to optimize space and give more room to the back. The USB-C plus was integrated to support GoPro bones but also to power the GoPro directly resulting in less weight.

Scientific Tuning Method by Leveraging the Blackbox
The tune was done by Ellisvanjason himself using a Scientific Tuning Method together with some final in field fine tuning by feel and eye. Different tools were used to read and interpret the data coming from the Blackbox to get the optimal flight behaviour. Further the tune was revised by a PID scientist get the last 5% out of this drone.

Recommendation
This is the Ellisvanjason tune for BOB57 which was fully tested and works great. If you change FC, ESC, Motor or Props the tune will be different. This tune works best when flying with a GoPro and Battery from 1400mah 6s to 3000mah 6s.
Performance tune: Change PWM Low in BLHeli32 from 48 to 24
Make sure the ESC are updated to 32.9
