GMade R1 Adjustable Limit Strap 

I mounted a sewing bobbin on a modified servo and ran braided microfilament from the bobbin to both axles. You can see the write-up on the project here: www.rccrawler.com/forum/general-crawlers/491032-radio-controlled-adjustable-limit-straps.html As far as locking the rear axle, I have an Axial transmission with a Vanquish Products Hurtz Dig installed. The dig unit enables me to disengage the rear wheels (front wheel drive) and lock the rear axle completely for tighter turns. You can see the write-up on the install here: www.rccrawler.com/forum/g-made-crawlers/488119-another-wraith-transmission-install.html I also have several other articles on improving the R1.

Hope these links help and hope you have a blast building your R1. If you have anymore questions, look me up here or on RC Crawler Forums (supermoturd).
