3) are the wide pitch pulleys a good buy?
1. no, yes they add more weight.
2. yes, good for weight savings AND heat dissipation
3. yes

i'm getting my 05R on Thursday, is there anything i should be aware of when building the kit?

1. should i use different shock oils?
2. do i need to prepare the belts in any way?
3. do the diffs need to be broken in?
4. what pinion gears do you recommend for general racing on a medium sized parking lot track? (probably going to be using a Novak Velocity 5.5 brushless system)
5. should i get softer shock springs? i've heard the stock ones are pretty stiff for most uses...
6. any other building tips that would make it come together easier?

thanks a lot guys.

Thanks for the help guys...and Chris

Which pulley do you need for the spool setup? The diff pulley or the one way pulley? And does anyone have the part number for the blue hex screws for the TA05?

Yes....I am already thinking about Nats!

The face of the 64DP gear seems to have a concave / chamfered area right by the 3mm clearance holes. I don't know what it looks like on the other side of the gear. Perhaps some 82 degree flat head screws (or whatever the metric equivelent is) would help in keeping the gear mounted flush against the hub.
The 48DP gear is indeed flat in the same area, which is what I'm using on my TA05R.
Interesting.

So what you are saying, if using the Robinson 64Dp spurs at your own risk of not working, or even with the lip they still work ok?

I would say that's correct. I have no way of measuirng the spur since I don't own one.

There is really nothing special that needs to be done to the R kit that I can think of. One little problem I had was an axle pin binding on the rear hub. It must have been some worst case scenario tolerance accumulation of all the parts involved. A little polishing up of the pin in my lathe and all was well.

The one thing I DID notice was after the first 2 initial runs there was a lot of adjustments to be made on the drive train. I had to tighten the front belt up a click and both of the ball diffs needed a lot of tightening. Since then everything has been good to go.

1. I don't use the kit shock oil simply because I don't know what viscosity it supposed to be comparable to.

2. Belts just need to be adjusted if they are too loose. Your belts will flip if they are too loose, but it's best to run them as loose as possible for a resistance free drive train.

3. The diff spring is the part that would need to be broken in on the diff. However, if you use pliers to compress the spring prior to installation, you will take care of most of the diff break-in process. You might also want to sand the diff rings with 600+ grit sandpaper.

4. I used to use an 18 tooth pinion with the stock TA05 06 module spur gear for a FDR of 8.75 when I ran my 5.5R (non-sintered rotor). I have since sold my original TA05 and bought a TA05R. Now I run more tame brushless motors and have not tried my 5.5R with the new sintered rotor. I'd guess that I'd try a FDR ~8.0 for a starting point with the 5.5R and a sintered rotor.

5. For a dual-diff setup or a spool setup, the yellow medium springs (they are colored white with the TA05R, but are still medium) worked well for me.

thanks. that had me confused as to why Tamiya would give you super stiff springs as a starting point. i hate when companies change up the colors on you like that.

also, since i should not use the stock oils, what weight shock oils do you all recommend as a good starting point for an unprepared parking lot track?
thanks for the help
