PErfect!!!! It worked like a charm, thanks Chris.
Now just found out that i need a pinion puller :D 

Let's go for stage 2 :D

You will likely need a pinion press as well as a puller 

Don't cheap out on these............quality tools will not only provide more accurate removal/installation, but, they will last !!

Hudy, JK, and Sloting Plus, are a few of the brands I would recommend. The Slot-it puller/press is also quite good , and , popular, but see if you can find the version with the anodised aluminum housing......the plastic/fibre housing  version has been known to  flex a bit.

Cheers

Chris,

Already ordered the Fibre one from Slot-it but already reserved for when available the Sloting Plus.

One more question, for the new V12 Motor, should i install the Resistor that comes with the RX-41 or it's not necessary?
The connections for the motor on to the little copper contacts i can solder directly right?

Sorry for all these questions but it's completely different from the 1/10 Electric i ran in the past.
