Here's a good link on some race proven setups for the Storm.
But don't force yourself into one of these setups. Do what FastEddy said, get used to the buggy in stock form. Use this link and the setups there as a guide. Compare what they use to what you use. You might even find that on certain things, your setup and the pro's setup are completely different. Who's setup is better ? The guy who's most comfortable with his buggy and that's usually the guy that crosses the finish line first.

RC Radios come in 3 main types: AM, FM and PCM. AM radios are very susceptible to noise and not recommended for competition. FM radios are fine but PCM or digital radios offer the best noise immunity. Most RTR controllers are either AM or FM with interchangable crystals (one for the xmtr and one for the rcvr). To change frequencies on these types of controllers you need to physically change the two crystals to that of another crystal set (to establish a different frequency). Synthesized controllers offer you the luxury of selecting any frequency (within that band of assigned frequencies) by simply selecting that particular frequency. The radio has them all designed into the unit, you just need to choose which one you want. Nothing to swap out, no extra crystal sets to purchase. FM Synthesized radios are the most common you will find at races.
Radio Modulation
AM: Stands for Amplitude Modulation which transmits by a variation in the amplitude of signals, it is subject to interference more than FM.
FM: Stands for Frequency Modulation which transmits signals by variations in frequency, reduces the risk of "glitches" due to signal interference.
PCM: Stands for Pulse Code Modulation uses binary code to digitize the signal, providing the most accurate signal possible.
