RE: PowerBox in Fei Bao hawk
many factors but it seems that the current draw of 8711's are very high like most digital servos - i have read it over and over in many forums and discussions and most every time it was concluded that a sudden current draw causes the supply to drop for an absolute split second below the rx minimum and causes it to lock out before even failsafe can activate- why do you think spektrum and horizon added the capacitor, special regulators etc - for this specific reason - anyway this can continue forever - the goal here should be the fix it and thats it!!
im out!!
