Aircraft
We taxied out and did a full run-up before takeoff.  Engine instruments looked good.  We went to takeoff and on the takeoff roll before hitting 80 knots we looked at the engine gauges and the right cylinder head temp.  It was over the red line and reading above 500 degrees.  I aborted the takeoff and taxied back into the gate.  Upon making the final 90 degree turn to park at the gate.  I noticed I lost full right rudder and was not able to turn and asked my FO (First Officer) to step on his right rudder to make the turn and he had no control.  Before I could shut off the engines; we hit one of the traffic cones that guide our passengers while boarding with the left propeller.  Everyone deplaned; no one was hurt.  Called [Maintenance Control] and [Operations Control].Not sure on the engine cylinder head temperature.  I think there might be a broke cable for the right rudder.
A Cessna Captain observed a high cylinder head temperature during the takeoff roll; resulting in a low speed rejected takeoff; followed by a loss of rudder pedal steering resulting in contact with a traffic cone.
