Hi! what does WCF mean? I have a bnew RS SD and a 2nd hand CGM. I haven't used both yet. I'm thinking of getting rid of one. We have medium and high bite tracks here. which should I keep? Thanks in advance!

Horatio

Sorry - WCF = Woven Carbon Fibre

As opposed to moulded composite resin/carbon fibre (like on the CGM).

Often both types are referred to simply as 'graphite'.

Joe: I'll check out team orion's site... thanks!

i say keep the cgm and get rid of rayspeed, the cgm is stiffer so it wil react better on a medium and high bite track like yours. i would use a flexier car, rayspeed, on low grip conditions as it woudl be easier to drive.

where i am everyone would call the cgm grpahite and the rayspeed or similar, carbon fibre.



also can you put a double topdeck on the ssg? do you just put 2 topdecks on with longer screws or do you have to glue the topdekcs together with something?

Hi guys, would apppreciate if anyone can help with the following questions

a) is there a weight difference between the ssg and black chassis.
b) what would be the lightest servo i could use with a futaba 3pk pcm transmitter.
c) also what is the best and lightest speedie on the market
d) titanium screws against std kit screws

as you can see i have a weight issue with my ssg last race i was 1630 grams with a personal transponder.

BRAD.

1630 grams seems stupidly heavy and you will certainly have to put your CGM on a very strict diet.

To answer what I can of your questions.

1. As far as I know SSG and black weigh the same.

2. I believe digital servos are a bit lighter. I use KO Propo.

3. I've seen some tiny speedos but I'm not sure I would trust them. I use a Novak GT7 which whilst not light, is reliable.

4. Titanium screws - a MUST.

Change to graphite susp. arms, towers, diff cases, etc.

Go for alloy driveshafts, lighter prop shaft and input shafts.

Hope that helps.

I think it's time I resurect my Yok and order the CGM conversion, I miss that car... Doesn't seem like I will regret doing it...

Whilst they're not wrong - they're not right either!

Graphite + Carbon Fibre = Exactly the same material.

In the USA, Graphite is the more commonly used term. In the UK, the term Carbon Fibre is more commonly used.

Composite Carbon Fibre/Composite Graphite is the material used on the CGM's chassis. It's basically a carbon reinforced plastic. (similar to FRP - fibre reinforced plastic & GRP glass reinforced plastic).

WCF - Woven Carbon Fibre is made from Carbon Fibre Cloth that is layered and coated with resin. The number of layers and also their orientation to each other determine the strength & stiffness of the WCF sheet. This is the material used on the RS. The SSG material differs slightly in as much that it has a silver surface which I believe is achieved by causing some sort of chemical reaction. More importantly from our point of view, it lacks the extra 45 degree weave that better quality WCF sheet has - thus the greater amount of flex across the chassis compared to after market chassis, like the RS for example.

Hope this helps.

Regards the CGM - it's stiffer because of the very nature of bath-tub type chassis. Incidentally, WCF bathtubs also exist which offer similar stiffness levels - but of course they look much nicer and cost loads

Perhaps one often overlooked feature of WCF is it's ability to remain stiff, even during really hot weather when track temps can get very high. Over the years, one critisism of the TC3 was a tendancy for the chassis to go 'soft' on hot race days.

Johnbull lives in Malta where it's really hot, so I guess if the CGM was going to suffer from heat, he'ld have told us about it by now -so I suppose it hasn't been an issue.

pheyhoe

yeah the carbon fibre tub chassis are probably the ultimate stiff chassis, you can get them for around £80 in th UK

I think the CGM weight issue is a major one, at least the main one why I haven't done the switch so far... I run old electronics, because I'm on a budget... Older airtronics servo with heavy metal gear, heavy CycloneTC speedo, lexan-mounted motor fan, this all counts... Not anybody wants to dump 50 bucks on a Ti screw set, or a QC2. And usually, lighter peripherics = smaller = expensive... The CGM tops a hefty 100gms more on the scale than the SSG from what I understand, and I'm still wondering whether to buy that TC3 lookalike or not.

Question about the steering system: Is it as slop-prone as the SSG's?

About that Halifax Victory: from what I read, rain kinda messed things up... Drescher in D is far from usual...

LAter,

hi,

i went to down to my LHS today for a change as they never normaly have anything decent, but i did see one yokomo packet all by itself but it was part number zs501s or zs502s which is the front or rear steel outdrives for the mr4tc and was wonderign if they are the same bits as the sd ones?

many thanks

Why the rayspeed is stiffer than stock ssg? Ssg has one plate more.

Tek Nickal

The quality of the Rayspeed carbon fiber is better. So it flexes less.
