Craig, why don't you and Jonathan come up one Monday night as well - the Atomic-Carbon posse all in one place! (I know it's a bit of a drive but what the hell hey!?).

Looking for a carpet set-up for my GB 01... What wt oil is most commonly used? I am using the TamTech aluminum shocks.
Thanks

I read on the UK Micro X forum where you mentioned a kickup mod. What is that? Thanks.

I run mine quite soft so 30W oil front and back. Can probably go up a bit. Some guys run up to 60W in the front. I've got rid of the Tamiya shocks and now use 3Racing shocks which in my opinion is a billion times better.

The kickup mod is where you remove the front kickup plate and then remove the 3 plastic lugs that are mounted on the chassis (simply snip them off using some flush cutters). That allows the front kickup plate to sit closer to the chassis and increase the kickup angle. I also had to dremel away a bit of the chassis to help the front A-arms clear (otherwise they bottom out before the chassis does!). It imporves the car no end.

Thanks. I didn't get the GB-01 because I didn't like how it had no front kickup and caster. Right now, I've got the GB-02 which has a whole different front, but drives okay (needs more steering, might dig out the Dremel). My 2nd Tamtech will probably be the GB-01 kit like yours.

Since you started with a kit, I take it you tried the CVA shocks as well? Between the CVA, Aeration and 3Racing, your favourite is the 3Racing? Did you have to use their ball studs or did you just snap the shocks onto your Tamiya ball studs? I test fitted my 3Racing Mini-T shocks on my Tamtech and they were a loose fit on the Tamiya studs. The included 3Racing studs were a better fit but I think they were a 2.5mm screw thread instead of 2.6 so I didn't want to experiment too much.

Hey frogger,

I tried to follow your example and run the HS85MG with the 3Racing steer rack but I've run into two hurdles - one is the servo screw isn't long enough and some odd size (M2.3?). 2nd is the Tamiya pin that is supposed to go through the 3Racing 620 bearings won't quite fit. Do I need to grind down the diameter some?

How did you do it?

Thanks.

You are correct, Hitec seems to think it's a brilliant idea to use screws that you can't buy anywhere! It is a 2.3mm or even a 2/56 screw - I have tried both and they both work fine. You'll struggle to find them though, I know Makita drills use 2.3mm internal screws. I got a pack of 2/56 screws from www.amazon.com (yes, I know, Amazon!)

The 3Racing pin on mine was tight but it did fit, I guess your best option would be to grind it down a tiny bit to reduce the diameter.

Get some pics up when you are done bud.

I bought some 2/56 screws today. Will put them on when I have some time

We can get both imperial and metric sizes here (Malaysia). It's those weird Japanese and Korean sizes that are hard to get (M2.3, M2.6, etc).

Will roll the pin around a spare cutting disk and see if I can get it to slim down.

Will post up the pics

Installed the steering last night. Mostly done except now I have to remove the steering cross bar and cut/grind away the outer ball stud mounts that are hitting the springs on my GB-02.

I tried doing the Jimmy mod and space out the shocks further but I already added 2mm worth of spacers and they were still being hit by the steering. I didn't want to add any more spacers otherwise I would be left with only 2mm left of screw threads on the ball studs.

Anyway, posted up the install pics on my site http://www.bigbigplanet.com/rccars/gb02

Here are the pics...
The 2/56" countersunk screw worked.

The pin needed sanding down slightly.


Wires neatly tucked under the servo mounting top plate.


The Ackermann actually got worse with the 3Racing bellcrank. Next stage would be to mod the bellcrank to run longer steering links.
