The 3 Point Harness is used to enhance your experience while using our Pilot Lanyard. Designed to be an add-on feature, these straps work with our already popular Adjustable Pilot Lanyard. Simply, attach our Patent Pending harness tabs to the back of any radio transmitter. Next attach the straps to the tabs, and Finally the straps to the D rings on the Lanyard. Now, you have full control of the radio while flying, especially for the people that fly 3D. No matter if you are a "pincher" or a "thumber" you will not believe how you were able to fly without out products.
