if i recall correctly, the instructions say specifically that the use of the xspeed without the gyro is not recommended. that being said, there are many other factors to consider including -and probably most importantly- tire compound. additionally, get to know your transmitter and how to tighten/widen the turning radius and understand that you've invested in 2 narrow track width cars which can have some difficulty handling cornering at high speeds. re: ics usb cable: u must use with winXP or Vista (iffy on vista, inoperable on 7). the ics settings only allow you to edit servo settings (response, speed, etc) and the degree to which the gyro assists driving.
