Howdy folks,

I'm done with the assembly and the body...

TRANSMISSION: As recommended by a few forum members, I assembled the tranny as per the instructions (3 shims back and front) and broke it in for 30 minutes with a old stocker (an old Pz5R, a real turd) in, under 5V, without the UJ's... The tranny now feels somewhat freer, but I'm not totally convinced. The motor pulled 10.4A on my T30 at the beginning, and ended up at 9A. So there obviously has been some improvement, but still it doesn't spin freely, it feels more like a belt-car, it's not binding, it's just dragging ... I didn't spray the bearings out, because I don't really feel like coping with the maintenance if I do (our carpet dust goes EVERYWHERE). Besides playing with the number of shims and spraying bearings out, is there any other tranny-freeing trick you would recommend?

SERVO MOUNTS: One other thing... the oval-shaped servo mounting hole (the one in the back) on my chassis was not coutersunked... Was yours? since I didn't really feel like messing up a new chassis with a badly placed dremel rip. I used servo tape and the front servo post only. It seems pretty well fixed, I doubt it'll ever move. However, I'd like to know if this is normal this hole was not countersunked on my car. How was yours?

Thanks for your answers,
Later,
Paul, getting ready to race electro
The oval servo mounting hole doesn't come sunk, but you can do it yourself with a file. It's well worth doing because it gives you a totally flat base to the car, which means that if you lay it on a flat surface you can tigten the top deck to get no tweak.

Transmission is mostly a case of good preparation and shimming. I still run the standard grease in the bearings, and I did a couple of run-in tests, my motor pulled about 0.2A more when the motor was installed and turning the whole transmission - not much considering the motor was pulling around 7A just to run (can't recall the exact figures).

btw masami rear shock tower looks different
Rear shock tower is the same, just shaved the edges/body mounting holes off.

The top deck looks modified for the center stiffener (under the four screws); rear comes out wide for the body posts -- not sure the purpose though. He also went back to the regular front tower for this race. It also looks like he has some pretty severe chassis lightening in front of the battery slots. And it looks like he is using a new battery strap with two posts up front and just the one in the rear.

Default Rear body posts on Masami's SD

Just a guess? Because of his low rider lid, the original body post mount might have been to tall?

it could be since my Bugatti (Chevron) sits too high with the stock shock plate, I think that the rayspeed conversion solves that problem.

Has anyone tried fitting the MR4TC SSG top deck on their SD (like in the Masami picture)?
It looks like the rear body mounts are actually attached to the top deck as it extends back past the rear gear box.

Lonestar: After trying different drivetrain preparations, I would recommend breaking in the drivetrain on the track rather than on the stand. When on the track, the tires have resistance from the road (carpet, whatever) which transfers to the drivetrain and breaks in the gears faster. When on the stand, the tires lack this resistance and so the drivetrain should take longer, maybe much longer, to break in.

that top deck is special masami stuff... not anything that is available as of now.

Hi,

I need a good carpet-setup with rubber tyres (like CS27 or Sorex28).

Thanks,
IH
