We shall continue to build my friend, in spite of everything. You may not recall I was rying years back to perfect the recoiling airsoft system in 1/16 scale. I succeed selling the design to Waltersons. I am trying to apply the recoiling system minus the airsoft part to the 1/6th scale Jagdpanther. But like the suspension any tank with a barrel guide could use this simple design. The reaction is fast, and the return much slower. I will keep you posted as it is a feature many I feel would enjoy having. Take Care.
