+ | |||
+ | Only the h101 code currently supports inverted flight and bi-directional escs. Not all escs/motors combinations will be able to reverse direction in the short amount of time needed, I recommend damped light as a esc feature as it will improve changeover time. | ||

- | Always consider that the quad may malfunction, | + | Keep in mind not to flash the fc with the escs powered. |
- | Always remove props when testing. Do not fly quads that have severe oscillation/ | + | In the H101 and the current CG023 , the FC will turn off PPM at failsafe and before bind, so it should be safe to flash, but just in case, I don't recommend. However, not safe if the tx is bound and on. |

+ | The h8green , and currently blue as it has not been updated, they are not safe to flash while the escs are powered. It's rare, but they can turn on (full power) if the signal cuts off at just the right time. | ||
