I'm wondering if any of you have any ideas to help me figure out a way to delay the deployment of the rear wing. I really want to have it pop out at around 75 mph as that seems like a more useful speed for activation.

Every time I wind out the motor in third gear and get off the throttle I've hit 60 mph and the wing keeps popping up during deceleration. I think 75 mph would be perfect and reduce wear and tear on the linkage and electric motor.

Any suggestions?
