hey rif, when will the blackbook rev5 finally come out ?
this morning i went to a machinist to drill a 3mm hole on the left side of the chassis (just a tad in front of the mid pulley mount) to install a 20 gram of ballast.
For the next rev till 5 we still trying to find perfect rear bevel diff set.
Should be more than 20 grams bro.. at least 45-50 grams if you were using FP-S9550 as steering servo.
With 60 grams it would change your car handling.. better direction.
Pyramid notes that the alu. mid pulley mount is way higher than plastic one so front belt would not scrub chasis anymore.
