About this product
This is an F405 flight controller paired with a BLS 35A Mini V2 four-in-one ESC on a 20x20 mounting pattern, sized for compact freestyle and cinewhoop builds. The two numbers that decide fit are the frame hole spacing and the current your motors pull at full throttle. Check your frame, motor and battery cell count against the stack before ordering.

Pros & cons
Pros
- Controller and ESC arrive as one stack, so wiring and pinout are already matched
- 35A per channel covers most 5-inch and cinewhoop motor sets
- 20x20 keeps the build low and light, which matters on sub-250 g airframes
Cons
- 20x20 is not compatible with the far more common 30.5x30.5 frames without an adapter
- Continuous versus burst current for the 35A rating is not spelled out
- No receiver, VTX or capacitor is included, so those are extra purchases
