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....

i just got a nice used 960 08' with a ton of spare and decided to go either 4s or 5s and am not sure. have the speedpassion conversion and have a question. what about 2wd - ie.. remove the side belt and front oneway? less strain on the electronics, lighter and can mount the battery(ies) perpendicular to the chassis. i am thinking like a large 1/12th scale with an infinitely more adjustable front end. with 4s power it could be lighter and still handle well. i race 1/12th and they eat up touring cars. i admit the set-up would be crucial to making it handle well....bnut isn't that half the fun it would also be a cheaper set-up to run as it would less strain on everything and won't need those big packs. lmk what you think
