Some questions on converting my savage

[doo540]

I currently have reverse locked-out on my MMM and use the Savage mech brakes. I run on everything from dirt, paved road, grass, gravel pits (the most fun) and baseball diamonds. I'm not sure how many battery packs have been thru it, but I did the conversion as soon as the truck was released, so a summer worth of driving. I hope the tranny lives, because I love to watch the truck shift thru the gears. I did destroy a servo saver steering arm and then a servo itself, I have the big Hitec sevro now with an additional sevro saver right on the servo. I really didnt like the truck until I installed the Losi tires and it made a huge night and day difference for me. I'm not sure why it eats the stock diff pinions, my b-revo has been thru one, but I would have thought the savage would be stronger. I also think I could gear up alittle if I wanted everything runs super cool with my current setup.
