FTFY

The FGX has a fluid filled diff but runs a gearbox.

Last friday I ran my F104 Pro for the first time ever. My only F1 experience prior has been a 103 on foams.

Anyway, my outer front tires were chattering like crazy, especially in tight 180's.
What can I do to fix this? Here's my set-up:

New TCS (shimizu) fronts and rear
Trinity Rubber Death Grip, full sauce on all tires

I tried both black and silver front springs- same result
Tried both 1 and 2* camber- same result
I have the servo setup horizontally/ laydown instead of stock, with the tierods set even/straight across. tierods were horizontal.
Tierods mounted on the front holes of steering blocks

So my question is, is this a matter of excessive caster, or a lack of ackerman?

Do you have any type of grease or fluid to dampen the front end? Something like 30 or 60K diff fluid will help.

Thanks, I'll try that in testing this week.

Hi guys ! What would be the best foam combo on a asphalt track medium - high traction? Thanks!

Exactly, the FGX it's not a direct drive chassis. Two Wheels is talking about direct drive.

Ran a set of the Ride R1 premounts yesterday and they worked really well, but had trouble with getting the front ride height down, due to the know issue of the king pin rubbing on the rim, the lowest i got was 6.5mm on the front

has anyone else been able to get it lower then this by fiddling with the spacers, im running with the option alloy knuckles.

and to get the rear end to stop hopping or bouncing when i go over bumps, would it be more droop?

thanks in advance

If you are running a shorty battery pack then move the pack forward about an inch if you are all the way back. More weight up front will really help this out.

Really like Robk's idea for front droop:
http://rcf1blog.blogspot.com/2012/10...ws-or-how.html

What do you guys think about using a droop screw with a flat head but can still adjust with a hex on the screw end?

Those screws sound pretty cool. Normal grub screws work great if you can't find the Durango ones though.

Thanks for the links. First time I have heard of this idea and RC FiA. Bummer since the last race was October 13th.

Kinda funny about front droop, I have one person saying run .5-1mm and another saying pull the front droop screws completely, and both are knowledgeable and fast
I need to try both back to back once I get those droop screws

Hi I)arkness

i try also this tire - is a very good tire

you have two options

1) 2 mm spacer ander the front suspension - i drive this so....

2) cut the front spring a little bit

i drive my car with 3mm front ride high

but the best right high for me is 4,5 in the front

greet herbert

i drive this t
