Thanks Erik,

Will stick with what I have as far as the Leopard. Maybe you'll find a better way to mod once you look at the elevation unit. Seems HL went backwards when they decided to change barrel movement and add 2 sounds with their Version 4 Tx. Who wants a KT sound when they have a modern tank. But most are toys that we like to upgrade with better stuff, still have my Chally with version 3 which I like the best. Hope you find a better solution to the Barrel click, click, click.
