Just like the thread states. I have a Slash with the original 2.4ghz and a waterproof xl5 and still the Titan. I'm running brushes motors but I'm building my slash for the beach or trailblazing...I'm more into the beach idea more I think about. Brushless is the way to go the beach and the sand will destroy my stock motors. Only planning on running 2s. Anyways is it worth doing the power up program or just sell each unit individually? I do have the tekin repro I need to get replace for about 100 but only problem is its not waterproof. Any thoughts?
