Nice! I was looking at those before. They remind me of a pan car with a big front end. Are they 1/12 or 1/10?

Hello,

I am new to pan cars and have no idea how to start addressing a couple of handling issues I am having. I bought an F6 used, in very good condition from a local racer that didn't have time to race anymore. The car is pretty good, but I am having two issues. One, I can't get enough steering without being on the edge of traction roll. If I put traction compound on the whole front tire, I spend a lot of time on two wheels. If I run less traction compound, I get a ton of under-steer. On a TC, I would lower the roll center and go to a softer anti-roll bar. I have no idea what to do on the F6!

Second, the car pulls left pretty hard under acceleration. I have tried adjusting the side springs using the 'nickel trick' where you put a nickel on top of each front tire and raise the nose to see which falls off first, then add pre-load to the opposite side spring. It's not bad as long the wheels aren't spinning, but if I get any rear wheel spin, I'm making a hard left. The diff is smooth. I have it about as tight as I can, but it still diffs out if I get on the throttle too soon in a tight corner.

My number one concern is the under-steer. I can control the wheel spin with more controlled throttle finger (but where's the fun in that?!), but it would be nice if it just spun the wheels in a straight line!

We run on a very small black carpet track, with medium to medium-high traction.

Thanks in advance!

Hey,

have you tried how hard it is to diff out manually? My diff is as light as possible (if I turn 1 wheel by hand, the other will automatically turn too) and I need real strenght to diff out. We run on black ETS Carpet too and I sauce all 4 wheels for 10 to 15mins and never had the issue of traction roll. I settet the car up as to manual except minor stuff. Mostly when one my cars pulls left/right when accelerating its either something basic (like toe in) or something was bend/loose. The whole frontend loves getting loose and the steering pins love to bend. Id check that first...

What tires are you running. Are you gluing the sidewall on the fronts. The car does have some inherent understeer in it but can be made to be more aggressive in the front. Trying to apply tc techniques don't really work being different formats of chassis but make sure you have the right tire right off the bat. Without that your just gonna get more frustrated. I spent months trying everything thing and was about to give up until a buddy handed me a set of his. Completely changed the whole car.

The diff is pretty tight. It won't spin the opposite wheel in the opposite direction without holding the spur gear. Should I loosen it up a bit. I cannot turn the spur gear by hand while holding both wheels. Should I loosen the diff some?

I looked over the front suspension, and I don't notice anything loose or bent.

Thanks for the info!

It appears that the tires are Sweeps. I don't know what version of Sweeps though. The front tires are glued. The previous owner up to and maybe a millimeter onto the tread. Through various unplanned meetings with walls due to the aforementioned under-steer, the glue has been worn off from the rim up to about 3 mm from the tread. So, essentially, there is a ring of glue starting about 3mm inside the tread to 1mm onto the tread, if that makes any sense.

What tires seem to work well for Black Carpet? I don't race any asphalt, so I am only worried about the black rug.

Thanks!

I run the Volante ETS wheels. I don't glue the sidewalls.
i run then because it's easy to get them and everybody runs them.

The sweeps have been hit or miss when I've used them. The go to tire for me has been either the crc tires or Pit Shimizu in the soft compunds. We run on black carpet that most times is very high bite and have been using a spool instead of a ball or gear diff. It takes some getting used to but diffinately helps the car.

I'm using one I got from roche USA for the evo f1. Just make sure to measure so the axle is centered. Get another left hand clamp hub to put on the right.

Wrong tires.

Volante could be good but I haven't tried them cus unavailable in my area.

I do know that pit Shimizu 571/572 are the instant ticket to success on our black carpet. Fyi CRC or tamiya 1031/1032 are rebranded pit Shimizu 571/572, exactly the same and are mighty for black carpet. Fronts can be too grippy sometimes so use your judgement to glue sidewalls or sauce less.
