No sure for servo, at least I tried to mount a 9650, but it is too big. THen I mount a very aged 12 sone servo, it is OK. So, just mount and use it.
FOr motor, what I tried so far is SP 's 11.5. and Novak XBR SC, no top speed indeed. I do believe it could handle 5.5 or even 3.5.
But the kit's spring (front and side) is too soft for high tracking track like TRC. RollOver very easy even if setup to 4mm front and rear. And make my BMW shell damage.....
Be ware the kit's screw, the look great but very easy to damage by screw driver, as they are very SOFT. |
