This is a pretty good truck, so long as you stick to nimh. On lipo, the esc and motor will overheat pretty quick.
I have had my granite mega 4x4 for a bit over a year. Only lasted 2 or three packs brushed, as I wanted to run lipo. I started to convert it to brushless, before the BLX was released. Found out the mega driveline can't really handle brushless, so started modding to make it work. Now, the BLX parts are available, so upgrades are easy. Currently I run a brushless combo similar to the BLX, and it is a little fireball, and very tough.
My build thread. Long, and goes off topic some. Some good running vids on the last page or two.
