Thanks, let me take pic tonite and share with u guys.
BTW, is there any trick when building the diff?
i have already sanded the bottom of the internal gears according to the manual.
And what about the washers ?
Please share your experience and data (how many washers (mm) )and how much should the gears be "sanded"
Mine one KO after 2 to 3 packs of battery. It is not 掃左 but the base of the large gear broke and it become two pieces. I am sure it won't happen if it is metal gear. I am using HW 120A + 3000 kV + 300000 diff oil. Maybe the 300000 oil is too sticky and the plastic gear cannot withstand the force.
My friend's one also KO (掃左) after 2 to 3 packs of battery. He is using 13.5T + 300000 diff oil.
