heres a link to the battery it's weight looks really good for a 1/8 onroad project. Just not sure if It'll be enough

let me know what you think

I think you will have good speed with that combo of motor and battery. Where were you thinking of mounting the battery? Most 1/8th chassis have a clearance of 30mm between the top and bottom decks (yours maybe different).
Keep us updated with some pics as you progress.

P.S.
For those interested, I took some new video footage of my car last weekend. I have to edit up a clip as I used 2 cameras at the one time.

I was thinking about using some 6mm carbonfiber, plastic, or plaxiglass flat spacers under the 5xscrews that hold the radio plate to give the additional height required and use plastic spacers on the chassis to possition the battery... I was even considering going with the 6S 4000 http://www.hobbycity.com/hobbycity/s...idproduct=7657 and switch the steering servo to lay on top of the radio tray to get the battery in but using a different kv motor.. My thoughts were the 2650kv combo maybe the better option if I could keep the weight low enough, but not sure if the run time will be any good........what do you think will work out better?

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.

There are 2 ways of thinking about this.
1. Do you want to race it against other gas 1/8ths or
2. Do you plan on just bashing?

If you want to race it I think keep the weight down. The biggest problem with my car is the handling, don't get me wrong it's easy to drive but it is no where near as nimble as it's gas counterparts due to it's weight (almost 2lbs heavier)

If you plan on just bashing go for battery capacity.

With regards to the spacers try your best to find batteries that will fit without modification. I think you will compromise the structural integrity of the car by using spacers.

hello, just wanted to input....there is a easier way,....Schumacher and Speed Passion came out with a "Brushless Conversion" for the 1/8 Serpent On Road Car. I dont have a Link for it, but it is out.....search....

thanks,,,,,

You mean THIS one???
I still haven't heard of anyone that has one. Did they even release it????

I am using that... Speedpassion conversion kit.. but with a lot of modification..

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?

Nice vid thanks. :)
I want a conversion for racing.
Shepperd new kit is like $800.
Just looking for a roller right now.
It would be really kool if Mike made a conversion.

I am looking to race against the other nitro 1/8's ...
We only have a short 150- 180 foot strait away the rest is technical really a 1/10th track thats been extended slihtly.....
Do you think a 4S 4000 mah battery be enough?

4s should be fine. Only testing will give you a true indication of run-time however.

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?
