I have started building an a7v in 1/6 scale off of a papermodel. do to size I may add interior details. time will tell. tracks will be panzerwerk panther links, and roadwheels will be knex medium hubs. and wright brother guns. the rest I will scratch build. rivets are 4mm half round pear beads. the build is going well. I also have researched some ww1 U-boats u-b88 and u-111 I will share plans for both. pm me. can some one show me how the running gear works. pretty sure it pivots off of the middle shaft. this I will build into my model. great sight. Craig how do I upload photos??
