Spektrum SR3500 DSM receiver, KO receiver, JR receiver, anything that's small size, good range and low noise. stay away from those single conversion one except KO/JR's (you may lose control and range a lot with the single conversion)
ESC and Motor are just up to your personal tast, they are pretty good as long as it is sensored. size and layout matter more I think.
servo, futaba's, BLS451 for long lasting, S9550 and S9551 for space saving. I use S9650 with the S9257's gear set. (35g saving)
the car, once again it is up to your tasty, they all are very good. just don't put a TT-01 on the track.
battery, lipo is the future, and now!
radio, just up to your tasty. the M11 and 3pk are popular.
you are very much on the honey as long as the total weight is about 1300g (without the cover body). don't forget to get some lead weights to do the balancing.
