The difference between the PTS50 landing gear design and older hand cranked competitive products is obvious right from the first glance: there is no crank! The gearing mechanism, an integral part of the cranked leg has been replaced by a pneumatic cylinder, this removes the components most susceptible to abuse and alleviates the need to lubricate the gearing to protect it from water intrusion, a very damaging element to the traditional design. Our PTS50 designed cylinders are sealed, self lubricating and require no maintenance.
