Does this mean that the Ti screw set is less prone to stripping, even if one is using good drivers? Also does anyone know if tower will be getting the Ti screw set in?

thanks Jason

Well I leaned a few nice tips for the R40 last night.

If you disconnect the side brace you will get a heap of extra rear grip, but the car is less consistent. I agree with Hara, and using the 2 screws instead of 4 really does make the car feel better balanced.

On my track with a ton of 180 degree turns standing the rear shocks up made the car tons better on power.

Lastly i installed the front diff instead of the oneway, and on a loose track the car was much more predictable. Lesson learned, if you drive the diff and it is no slower use it!

I had called RC Screwz a while back and they told me that there is a difference in the dimensions the mfg's use to produce both the tool tips and screw heads. The US produced screws and tools are a shade larger then those produces overseas. RC Screwz explained that all of the overseas products are made using metric sizes converted from us feet and inches and that they didn't use enough precision to do the conversion.

The end result is that you need to use a hex driver produced in the US to get a good fit.

I always thought 2mm was 2mm everywhere.

I use the HPI Ti screwset with the HUDY 2mm drivers and they are a perfect fit.

found out while cleanining the car,the OFNA,Brand new,purple wheel nut came loose,and stripped the hub(OFNA quality continues to impress me)......so all in all,not bad for an old man with 3 wheel drive......

Had a great time.......THANKS hpi!!!!!!!!!!!!!!!!!!!!!!!!!!

Yup!

On and off once or twice and they're done. GS aren't much better either. Too risky

Although much better, HPI and Tamiya aluminum wheel nuts should be changed every 6-10 on and off cycles especially for nitro on-road.

Seems like locknuts made from aluminum need to use a softer locking plastic material than steel locknuts to prevent stripping or stretching the aluminum nut itself. Ever noticed how much harder it is to thread on a steel locknut?

Hara used the stock purple side brace PLATE (or you are talking about the bridge at the 2-speed side..?) and only used 2 screws instead of 4? Which 2..? Upper 2 or lower 2?
Just want to give that a try.........
Diff are more predictable on tight track........1-way are more speed and high power.......it really depends on the driver driving habbit.......for me, I can't handle 1-way, I like to know exactly where my car will go instead of guessing the car where she will go.....

I use the graphite brace myself, but yes I am talking about the purple brace plate. Thad mentioned that Hara used only two screws in the top, which I myself did, and I found that it made a very subtle difference to the feel on the rear of the car. I used the two screws on the left (ie. no screws to the rear of the car) and the car made a ton of rear traction. In fact it understeered badly. So I guess if you are really struggling for rear grip and you need a quick fix there it is. Having no rear screws does make the car less consistent.

I always use a one-way diff on every touring car I drive, I generally dont like front diffs I find them too hard to drive. However what I did find out was that in difficult conditions (the track was pretty slippery) the oneway setup I found was as fast as the diff setup I used (I used black front and gold rear springs as the only difference) and the diff setup ended up being a much more consistent setup (ie my standard deviation was much lower). This was something I had never tried before. Of course when the grip is high enough a one-way will always be superior.
