I know from 99L that at cruise speeds without a speed control rheostat to slow the tabs down that they're too sensitive - slightest tap on the switch causes a "bump". Ttcwtech.com has a $49 speed switch that they sell that can be used to set a speed where the sensitivity changes - up to 145 kts. Is it good enough to have a speed control rheostat cut in to slow the tabs down once the gear and flaps are up? Or, has anyone found a rheostat that's directly driven by the airspeed so that the sensitivity is always in proportion to flight speed? Other ideas?
