ok, so from what I understand, there are two types of 64 pitch gears. there are standard 64 pitch and metric (Tamiya) 64 pitch. am i right? and the metric (Tamiya) 64 pitch gears are hard to come by in the US, so we should switch to standard 64 pitch, which are easier to find. is this right?

Save yourself a lot of confusion and don't ever refer to the Tamiya gears as "metric 64 pitch". The gears have nothing to do with inches. It is a 0.4 module gear, a widely accepted metric pitch, which just happens to be quite close in size to 64dp.

What is even worse is when people call 0.6 module "metric 48dp". 0.6mod isn't even within shouting distance of 48dp.

Change the gear to whatever you want, whatever is easiest for you to use, it takes standard sized spur gears.

I wonder how many times the metric and imperial debate will go on....

.6m is equivalent to 32dp
.5m is equivalnet to 48dp
.4m is equivalent to 64dp

BUT

Although you can run them todether, they don't work right, and will causing a rolling resistance, so running 64dp pinions on a .4m spur basicaly cancels out any advantage of running fine pitch, which is lower rolling resistance!!!

Metric and imperial screws don't mix, nor bearings, nor gears, simple as.

is this rolling resistance noticeable to the club racer or is it nothing to worry about at my level of competition (i'll be using novak Velocity GTB system)?

also, what number of teeth for the pinion gears do you all recommend? i am looking at getting a few to start off with, maybe four. again i'll be using a brushless Velocity system, probably the 3.5 (choked down on the radio of course).

I purchased aluminum suspension blocks and noticed you need some kind of "plastic ball" for them. Anyone know the part # for it? Also, does it come in the standard TA05 tree?

I don't know about any plastic balls, but these are what you use with aluminum blocks:

The suspension balls you need are not plastic!
The Tamiya Part you need is 53709 fluorine coated suspension balls or the standard 50994 suspension balls.

Either pay the extra money for the .4mod pinions or go buy a 48dp spur and pinions.... or 64dp pinions and spur. If yougot 48/64dp you are almost garaunteed to be able to get spares trackside.

Default Static Glitching

I was running my R on tarmac and it was glitching periodically, and I thought it was the ESC. I looked at it tonight and watched a big spark jump from the bulkhead to the ESC, which caused the ESC to momentarily stop, which is also why I lost my steering for a split second (but long enough to put me into a wall! ) since the ESC would cut power to the servo.

I also noticed (as I tried to reproduce the sparks, which I was able to do with ease) a smaller spark jump from the bulkhead screw to the servo saver screw. This luckily didn't affect my servo.

I managed to reproduce the sparking to the servo on my sons R, but couldn't reproduce the ESC spark even though both cars are set up the same. My ESC is a oriented 90 degrees to his though, maybe that made a difference.

I did the 'KO' fix to the front and back and the sparks were gone as was the glitching.

It seems like Tamiya should come out with a better fix than me running 2 wires in my cars.

One other interesting 'fix' that worked was putting body post foam pads in between the bulkhead and the ESC and Servo. However, I didn't test this for a prolonged period of time and figured the static would just continue to build up and then pass through the foam insulation.

I didn't think too much about this static stuff but I'm a believer now!

I've asked this before, but damned if I can find the info in the eleventy billion pages .

What range of 64dp spurs and pinions can you fit to the '05?

Cheers.

It looks like those really nice robinson racing spurs will fit, someone mentioned that a few pages back.

Ahhh, sorry. I meant size spur/pinion, i.e amount of teeth.
