also the lightweight chassis looks wicked awesome....to bad i blew all my cash on the towers, 2speed shafts and hudy setup system.......ahh well....

Darkseid - if u find the lightweight upper deck and lightweight reciever case tell me....ive been lookin for that thing for who knows how long...

AMGRacer - i wouldnt suggest the rubber tires.....only bc HPI discourages the use of rubbers on the chassis bc it was only tested on foams so you may not like what you see.......
Some people have no choice but to race on rubber tires. Not all clubs and races allow foams.

Also, Hara used the Proceed Red spring on his R40 at the 2003 ROAR Fuel-sedan Nationals. I am going to a track very similar in size and traction. Does anyone know the rating on these springs and what Associated spring they are most similar to.

Thanks.

Then FAQ / Tuning Guide / Level One Adjustments.

The proceed spring rates are listed there but not the R40.

The R40 on rubber tires:

The main local club track that I run on is concrete. The car runs get on rubber tires if you have to right set-up. I have found a set-up in which I can switch between foam and rubber tires and the car handles almost identically on concrete or asphalt. This is also with the front diff in the car. The key is finding that dual/neutral set-up. In fact, in testing my R40 and MTX-3 on asphalt this past weekend, my R40 seemed faster than my Mugen and it has the older Sirio and stock 1.0 gears and my MTX-3 has the new Evo 2 Sirio with stock 1.0 gears and is 100 grams lighter. Just my $0.02.

Well, I've only bought two pinions of the current set(one tooth up for both 1st and 2nd) so thats not a problem for me. The stock gearing was perfect for my track.

I have a few extra bucks, so I'll be able to swing the chassis and shafts at the same time...now that I actually want to buy them.

I found the HPI upper deck at RCModel. I'm going to see if I can get it through special order at the LHS first, but if I can't, then I'll go to RCModel. Also, the 3 Racing lightweight upper deck looks good...and cost half as much.

It is not much lighter. It comes on the 2004 Spec Edition, and it is a little more open.

Cool see you there! I am running in open with a MT12 so I have chosen the 36R since last time my rears were overheating badly. What inserts do you run, I have the Sorex Medium racing profiles...........

I have a pretty good wynnum setup from my old V1RR so I am hoping that some of it translates over ok............

I have that OS 12cv in this R40 and haven't be able to get off work to run it at a meet yet, but it seems to stick better with 32R than 36R the way it is at the moment. Sorex B Medium inserts appear to work best for me. Some of the guys only run 36R regardless. I believe some of the open guys were running speedmind racing profile medium inserts on their snakes and mugens but those appear to have gone off the market so maybe the Sorex C would be similar to them.

That one in the pic is the 3 Racing upper deck. It doesn't have as many relief points as the HPI lightweight upper deck does, but it does have some. RCModel charges $24.00 for that upper deck, while the HPI unit is a whopping $48.00.

I've been taking a close, close look at a larger, more clear pic of the HPI lightweight upper deck.



I think instead of dumping $48 on theirs, I'll simply modify mine. I'll simply resize, print, and trim the pic I have until it works as a guide for where to cut/drill my current upper deck. I've done stuff much harder than that before, so this wont be too much work.

Thats $48 I can spend somewhere else!

Thats exactly what I wanted to do> I was waiting till I guy I know with a 2004 was able to loan me his to trace.
Thanks for the picture

A Dremel would work. Don't use too aggresive a bit. Slow is better and neater. Make sure you were a dust mask.
