Jump to navigationJump to search
The Team BlackSheep (TBS) Discovery is a purpose made FPV platform based on the DJI Flame Wheel F450 frame base. It has a asymmetric structure, incorporates traces on the central structure plates to minimize wiring, has space for both a flight camera and HD recording camera (GoPro) in the front and a protective cage for a high capacity LiPo battery in the back.

Tips and tricks
- To get rid of vibrationse, use only good quality propellers, e.g. Graupner [25] [26]
- For longer flight times, use low Kv motors and large propellers but watch the power usage
- To avoid propellers in the GoPro view, use Wide setting for 8-inch propellers and Medium for 10-inch propellers
- A 25A ESC is more than enough for this frame, max. 60A full throttle for all four controllers equals 15A per ESC, 10A margin [27]
- To a clean ESC install, solder the 3.5 mm socket motor connectors directly on the controller board [28]
- The standard DJI motor and propellers use a 8 mm shaft/bell, APC props are 6 mm and has to be adjusted, Graupner is 8 mm [29]
- Program the ESCs to be set up with Break off, Battery type NiMh (not LiPo, to turn off voltage cut-off), Cut-off type: soft cut, Cut-off voltage low, Aircraft type airplane, Start mode normal, Timing/response mode high (400 Hz), Governor off [30]
- Calibrate the throttle range for each ESC individually by setting the throttle stick high on power on and then low until a confirmation beep is heard
- Consider upgrading the ESC firmware to SimonK version get the full refresh rate needed for multirotors, RapidESC database shows all capable controllers
