I'm glad for you, that your inside work was a success. I feel, any form of electronics would benifit from these modification details, because of less driveline resistance and heat damaging build up of electrical parts. It's already bad enough that we expect these tanks to perform similar to the real ones, but, they do have their limitations. I also want to mention, that I went one step further by lubricating my tanks metal tracks to eliminate any power robbing resistance.[sm=punching.gif][sm=wink_smile.gif]
