i have been asked By A Reviewer , did i mange to stop rotational movement of the sub chassis ,because of the use of 0-rings ,this was because Gert Pederson's Gyro uses Kevlar wire to stop this movement, his design is out side the pylon creating a pivot points for the o-rings to move, the design i made uses the original suspension posts , it is kept with in the engineering design points the covers will fit back on , having put that i looked at the design again ,there was no movement i tested this with a DTI ,but i had a concern that if the o-ring snapped it would drop the deck and may cause damage to the Cartridge, so i made the 6 o-ring version , with 6 hooks in either part , so if one or 2 o-rings snapped through being heavy handed when putting the clamp on it would not make any difference , i also made sure the Chassis would only move up and down when the clamp is fitted and cannot be twisted ,there is NO rotational Movement in my design , so no need to add wires, the design is kept with in the original suspension , requires no drilling , no special tools to fit , (but is a pain to fit new o-rings ) or added weight like plastic padding , sand etc , or feet , They are easy to fit and hide, the Deck can be returned back to Normal with out any Holes been left
