this is my first turtlemode brushedwhoop
when i do this build, i tried some configuration to enable turtlemode on a brushed whoop, since the power of a brushed motor is not as powerful as brushless, the weight of overall whoop became matters. first trial i went using 716 19000kv boldclash and betafpv 65mm frame, the turtlemode fail. so, i bought cockroach frame and some unicorn motor, et voila, it works.

so far the eachine turtlebee is my fave brushed FC

although after some power drop below 3.7v the turtle mode fails due to lack of power.
some says on FB groups that brushed motor that using turtle mode will shorten its endurace, idk if its true or not but, hey, its a fun gimmick to reduce your walk of shame :D
