There is no one at our track that takes a computer to the track for the purpose of calculating anything.

btw, good luck. From the sounds of it, you will need it.
Why do you make assumptions as to what would happen to my equipment? Didnt I just mention at the beggining of this that I would ask somebody what they were geared at and go from there? And observe!!! Why dont you read before you reply. Ill take my 5th grade edumacation and will be having fun racing. Go immerse yourself in more rollout calculations.
This is fun I cannot believe how many people have responded to my rant!
Im gonna start a no rollout revolution!!!!!
LOL!! By the way Timmay speaking of me needing luck...I got lucky last night Did you?!

I thought you were kidding after all the previous posts arguing about spur and pinions and how gearing the same as someone else is useless unless you are running the same diameter tyres as them.

Damn straight. That's authored by Scottrick, he's real smart!
Even if you think you understand rollout you should read this.

I will run either a 5.5 or a 4.5 Novak motor with 4 cell.


2nd. question:
Are there any other ride height adjusters available besides the one that are
included in the kit? number?
If you want to get silly with rear ride height adjustment you can get the Xenon ride height adjusters, which go in .25mm increments. They are real costy, though

Sorry, but you have to ask a complete question. 17.5? 13.5? mod?

All the guys there that I know that ran 17.5 rolled out at between 80 and 90mm. You pretty much have to use a 76 tooth spur (or close to that) to achieve those high numbers. In the main I ran 49/76 with a 44mm tire. Thats 89mm rollout

Different brands of 19t require different gearing. The most popular brushed 19 around here is the Komodo which likes a rollout around 48mm. Most of the other motors gear higher, Reedys run in the 50s and Checkpoint $ higher than Reedy

for my novak 17.5 I ran a 98.4mm in "A" 3 at the nats and it slowed down 2 tenths. forgot to temp it but it was hot. that's a 3.87 for us yanks. that was also at the hottest part of the day. the best run I ran in "A" 1 which was second fastest in the "A"s at the nats behind Kyle and faster then stelfule, the roll was 101.8mm or 4.01" and the motor came off at 135F (sorry everybody else you'll have to convert that to C) but that was about 11am so the track was cool and the sun hadn't really come out. I think the 98mm is prabably the best for a track with 150' or 45m straight. I run on a smaller track locally 100' or 30m and I run a 96mm or so. it really depends on the infield for some tracks. I ran a 89mm or 3.5" at the carpet nats and was only a few tenths off the fast guys with my 17.5 on a 85' or 25m track. I'm not fast but I bet if someone fast was driving my car they would be with that rollout.

tell me how this works?

or this you can print out and take to the track.

OK that gives me somewhere to start, At this stage I haven't run anything in the car as its still being set up. I was also thinking as this is my first venture into 1/12th it might be a good idea to start with a CO27 and get the feel for it. Any tips and roll out start points for this motor? I think the straight is around 35-45 meters give or take.

You should start the CO27 (with most brush/spring combos) around 48mm rollout and adjust from there.

We ran the Komodo 19T around 52mm rollout.

OK, what page is the carpet setup... hopefully I will set my car on carpet later today and race tomorrow. Who's stocking spares for this kit?

Is it possible that the Parma EXP Speed 8 won't fit on this car?
The body "scratches" in the area of the rear pod when i mount is as
low as a Protoform Speed 12.

Will the Zytek fit?

Mine definitely rubs with the Parma Speed 8. It's the front edge of the upper pod plate at the side shock attachment point that hits the body. The Protoform Speed 12 clears, and the Parma Speed 8 HD seems to clear as well.

I haven't tried the Zytek.

I have an idea for a fix to this (I really like the Speed 8, this issue bugs me)

I'll post pictures if it works out.

This is the best 1/12 I have ever owned. I do need more steering for mod. I am running stock set up with Parma Magenta, Coral's, any help?

fred, try a stiffer side spring on the car, I noticed the kit ones are a bit on the soft side compared to most of the other link cars out there. I'm going with a set of the Speedmerchant .021 side springs this weekend. I've also got a set of .023 to try if I still want more... If the car starts to feel darty you might want to go up to 25 wt. oil in the side damper to calm it down a bit...

I found a setup I can use for this weekend. I will try different tires to tighten-it-up more...

I ended up using a red center spring and red CRC side springs. Hole two on the shock tower. 27-1/2 Losi shock oil in the side dampener. Stock front springs. 3mm front/back ride height with a tiny bit of sag in the center. And the car was stuck with a 17.5, Lilac/Pink tires.

Will experiment with other shores and a Protoform 12 body...
