There is a slight binding at each end of the travel range and a corresponding current peak.
Ah...as I thought... Thanks! It would not make sense to incorporate limit switches, etc... way too complicated.
With retract retrofit actuators like mine, you really can not use limit switches as this "limit" (i.e. actuator throw) as the stall current would vary from retract to retract. One function I plan to mess with tonight is a stall-learning feature where every time you power up the gear, it learns/memorizes the stall current for both directions (full up/down). This is important because this stall current could (and probably would) be different from retract to retract, and, over time after flying, this stall condition might change (i.e. retract start binding, lack or lube, etc...). So much to consider...
