Default RE: Stall current

dirtybird,

You have a tremendous amount of effort in servo evaluation. You already know that servos are expensive and most guess at the requirements and overspend on servos both in torque and number of servos per surface.

Have you evaluated boost tabs and their effectiveness at reducing servo loads? The proponents suggest that servo load might be reduced by as much as 85% with a passive tab. While the 85% number is probably overly optimistic the concept seems sound from an engineering perspective and uses the slipstream to counterbalance the load against the servo.

I am attempting to measure the effectiveness of a simple boost tab by measuring the servo current with and without tab. If it works $3 in parts to replace $100 additional servo expenditure seems like a good approach.

Thanks.

Bill


I often wonder why we commit a lifetime of knowledge to such mundane activities.
