Seems the brake mount block in 966 lays more forward than 960... which need to think a bit more on how to mount the motor....

For anyone interested in doing one of these conversions, forget about doing them to Mugen's or Serpents. What you want to get is a Shepperd racing VeloX (click here) If you look closely they have done away with the disc brake on the transmission shaft and incorporated the brake into the rear axle/diff. What this all means is there is a huge amount of room to fit your motor and still keep the mechanical brakes.

What benefit (or problems) of using mechanical brake vs. motor braking ?
As I still testing the motor direct drive (45S/18P), braking to the car seems no problem up-to-now...

Shepperd design is great for conversion, but the drawback is lack of support and parts in Asia region.....

Mainly heat build up in the ESC. as the kinetic energy of the car is transferred to heat via the ESC FET's. (some energy does however also go back into the battery)

I think there are pro and cons to both ways of braking.

That would be a problem.


Have you got any video yet Sam?

Sam those video's are awesome.

Where is that track located? It looks great!

In the 5S vid you can really see the punch that thing has

Whats you next modification?

Track is in Hong Kong... which mainly for 1/10 GP...as this indoor facility is very good, I test my 1/8 EP .... until satisfied .. then will go to another track and race with 1/8 GP.....

5S is my final target.. and I am now testing the gear ratio for safe-ride.....

Up-to-date test find-out is... 4S with 2350kv or above.. torque is not enough, some kind of mis-matching.... motor very very hot...

and 5S with Losi 2100kv gives a good balance between top speed and torque.... and now carefully lowering the gear ratio.....under motor temperature around 65 deg cel....
