New from Sask.
Hi folks. Just joined and thought I should introduce myself. Old and Retired!
I am mainly interested in building a RC model Caterpillar D7, 1947 vintage. Hoping someone would have some suggestions for a couple of stumbling blocks I foresee. First, the original D7 was a cable operated dozer ie no hydrolics, and I see no method to get the dozer to dig unless a VERY heavy dozer blade is made. A servo or actuator would be under constant strain to keep the blade off the ground.
Second problem would be to keep model close to scale looking, and get the power to rear drive sprockets. Open to suggestions and ideas as I know there are a couple of people on this forum who have built model Cats in the past. Thanks.
