A Lazer Zx-r for racing

[Ema]

For all bored Lazer (and kyosho in general) fanatic I think it's time to start a new thread .

Probably someone will remember my restoration one (here: http://www.oople.com/forums/showthread.php?t=37223); unfortunately still not complete as I have to wait the Kamtec body repro ....
However as promised there it is finally time to build another Lazer but this time for racing !!!

And when I say racing it means that will run among modern cars (Schumacher, Durango, Associated, Hot Bodies, and so on ....); do you think I am totaly crazy ?
Onestly I don't thik so, however I'd like to read your opinion (and advice ...) here.

Ok, let's stop talking, it's time to start !!

Problem 1: the battery placment.

I decided to run again the zx-r chassis because it is possible to choose the battery configuration you prefer.
Honestly I don't like at all the saddle configuration, so I have to found a way to secure the stick lipo battery.

My idea is quite simple, I use a small pice of teflon in order to secure the battery at the rear and I get some rc12 body mount in order to replace the standard battery ones because they are too short to use with a lipo.

I know it is possible to make a better holder, however using this solution I did not modify the chassis and/or any lazer parts, so I can improve the design in the future (probably the weight distribution is not the best available ...).

I can see one problem, the belt rubbing the battery. Ive designed the lipo saddle pack holder so why not use that.

Don't worry , I already checked that there will be enough clearance between the battery and other elements.

You have also to consider that this is an MKII chassis, so the batteries(battery) are (is) placed a little backward compared to the standard one and the belt is a little higher in that position.

At the moment I only own stick lipo battery and I also like the idea of having less wires inside the car, however I don't made any chassis modification, so if I change my mind I can return to saddle configuration.

P.S. I'm glad to know you suggestions as your knoweledge on the Lazer platform is really huge .

Some fresh parts before starting the build !!!

A new set of rubber shielded bearing ....


A Zx-r MkII motor plate (new) and an good condition 48dp Rw Racing spur gear (hope it will do a good job in the slipper department)


Together with the MKII motor mount it's necessary to use the latest kind of LA31, the one with the recessed area for the motor

Another choice ... gear or ball diffs ?

I'm tempted to start with the gear diff because I prefer the easy maintenance, at leat during the first test runs.

Plus for the ball diffs I'd like to wait the new "Welshy Design" smoother pulley !
