[Suggestion] acceleration limiter on motors

[Ruedii]

One of the ways to limit heavy vehicle torquing on propeller motors without using a torque limit is to use an acceleration limiter.    This would be very useful to implement.  It would allow even propeller load torque without allowing heavy spinup torque.

The other part that can use these is wheels as a means to reduce slippage.

Hmmm. I think traction control will do this on wheels. I don't think this is as useful for prop planes, since startup torque is less of a problem than sustained torque in flight.

Sustained torque in flight is steady and can be corrected with trim (unless you are in the habit of suddenly changing your propeller angle instead of slowly changing it.) Spinup torque is horribly sudden. 

Also, when you make robotic wheels and other ground rotors they don't have traction control.   This would basically provide them with traction control.  This is literally what traction control is.

Currently, the improvised solution I use is to turn down my engine torque during takeoff to reduce the spinup torque.

I'm thinking of adding some computer units to the planes to "smooth" any transitions as well.  This could help a lot.
