Want more usable power, lock your center diff or go with what I use in my 1/8 scales, the Ofna solid center. I was having similar issues with my 14lbs (Maybe more when I use 5S2P TP Extreme the long ones lol) as it would just unload all the power to the front wheels. I tried different diff oil and went up to 100K and it would still unload. After I installed the solid center, it became just like my 4WD 1/10 scale and drives like it too, but not with the 5S2P lol. I can do wheelies anytime I feel like it. Look at this picture, it's a perfect match for the 1527
