Do you guys have 1/12th scale donuts? Maybe I'm blind, but I don't see any.

i have been reading regarding the Cross F1 and most user has said to encounter oversteer using the inline battery mounting.... currently running stock setting but i have huge understeer...anyone could help me out to give the car to have more steering??i'm running HBR medium front & rear.....should i change to soft front??i prefer not to change the tires ....so what settings would i need to change...my steering servo also seems to be very slow...which servo is best for F1(fast servo)
by the way does a gear ratio of 4.08(94/23) seems good for a Sport Tuned RS540...

Ha! Wanna trade cars? I run my Cross car battery in the "Tamiya style" configuration and it still has way too much steering and is horribly twitchy. I'm using a Hitec micro bb servo. Sorry, can't remember the model#. Usually you want to run the softest tires you can get in back and a harder compound up front. When I ran Tamiya HBR tires, I ran mediums up front and soft in back. You can also run purple up front and pink (for asphalt) or grey (for carpet) in rear. I may try red or blue up front, but I'm much faster in my Tamiya car.

I run a gear ratio of 3.62 or 3.45. So far it is working for me, I have good take of speed and top end. Once you get into the 4 range you motor will start to warm up.

The lower your final ratio is, the hotter the motor will be. So if you go from 3.45-3.62 up into the 4 area, your motor will actually be cooler.

You should set your gearing so that you top out on speed as you reach the end of your longest straitaway and tune from there. I race at several tracks and they are always different configurations, so I change my gearing for every race depending on the track layout.

good point pyscho.

I put that P2K2 in my F-1. 100t spur with a 19T pinion. pretty fast but it will be interesting to see if my 2000 battery packs will last 5 minutes, since they've been running with the RS 540 motor

Unfortunately, the only way I have found to fix the oversteer problems with my Cross car is to race my Tamiya F103. I run 3.5mm ride height and it is way twitchy, even with 15 degrees of caster. I don't have a good answer for you. I think that running reds or blues up front will help a lot, but I'm not sure if you will be able to carry as much speed into a turn. I may try that once I feel comfortable about scratching a race to experiment. Try turning down your dual rate or using steering exponential (if you have it.) Neither of those things made the car feel right on the tracks I race at.
