speaking of standardization, i think the issue is real F1 keeps changing, wings get taller or change etc.. Unlike Touring cars, which everything has a body over the wheels.

Tamiya F103 represented 90s f1 imo, wide stance and wide tires. HPI Super F1 was close in dimensions imo..

HPI F10 looks like the old 04-07 F1 cars

I think only way to classify them is by the era of f1 they represent imo.. Say vintage f1 wiht pan chassis, and modern class with 2004+ style bodies and new chassis imo

That's a good idea, but would you have the Fgx 190mm , and independent rear race with the 180mm cars ???

What bodies do fit on that car? Only 3Racing body?

Is there a shop in Germany which sells them? Shipping rate from US is expensive

try the car with the supplied gear diff before you think about a ball diff, i think it will work just fine unless you are planning to go bashing around your local parking lot, then a balldiff might be a better choice

and when buildning the gear diff, follow this tips:http://os.3racing.hk/articles.php?articles_key=133
and you will end up with a leak free diff, remember that it will take 2-3packs to get the diff to work perfectly

It looks like it has same transmission like Sakura FF.. so FF's diff propably will work.. But why you think it'll be undriveable with gear diff? It's not car with solid axle and gear diff is oil-filled, you can't know, that this won't work - all other RWDs has free, open diff with solid axle

btw why it has diff bearings in excentric mounts like bevel-driven chassis? Maybe preparation for Sakura's upper bulkhead with damper stay for TC version?

I race on CRC carpet indoors; so which of the Ride tires does anyone recommend? I noticed there are several different compounds from Ride for the FGX. We plan on keeping everything scale, which includes the use of rubber tires only, no foams allowed.

Also, I am trying to decide between silver can motor and 2 cell lipo; or 17.5 brushless with 1 cell lipo and no blinky esc.

Any suggestions would be appreciated

I want to run that car with a Novak 4.5t motor, that's why I want a (12ball) ball diff . Gear diffs in 2WD can't take the power of a 7t brushed motor, let alone 4.5t brushless. Also I hate messing around with oil, I'd rather use the ball diff screws... Ball diffs don't have blowing up issues at all ! Maybe more rebuilds , but that's it... I also want to be able to use the same diff settings for 21.5t blinky, if I decide to run stock: no need to be changing oils, etc.....

By the way, the diff that can handle a 4.5t will easily handle a 21.5t, and might consequently last a bit longer between rebuilds....

What world do you live in where ball diffs are more durable than gear diffs? Ball diffs can't take a lot of power, thats why everything is moving to gear diffs now.

I was referring to tamiya f103gt style strong ball diffs that I put kimbrough(12hole) spur gears into : it handles a 3.5t motor with ease, even though it's a different design than the tc diffs. I see 3racing sakura zero's running with a ten roller ball diff now, and a stronger 2.6mm diff bolt. I wonder how that is working so far versus a conventional (12ball) ball diff . If the bolt popping issue is solved that way, I would definitely go for it instead of a gear diff ... Lastly no ball diff would have an issue running a 21.5t motor, and I don't think most racers will be putting 4.5's in their F1 cars anyway, so a ball diff is a better option to me....

4.5t motor in a rwd will be impossible to drive, no matter what you try, its a waste of time and money

the ball diff will slip alot and might give you more traction, but it wont last long with a 4.5t!

and another thing is that you`ll need really good tires to get all the traction down, and with so much power they wont last long either

I want to get the car ready for all classes, stock or mod , with just a motor and gearing change . Also you are right about the slipping in mod that makes it easier to drive than a gear diff. I could never get my Nikko F1 gear diff to put the power down correctly with any mod motor more powerful than a 10turn brushed, and even then it did not last long . I already have a ton of ball diff hardware . None of my other cars have a gear diff, and I want to keep it that way .
