Yeah, according to the information you provided, the top speed is around 26mph. 5" tires are a bit small - stock Talons are 5.9", which would bring your speed up to ~31mph.

A stock revo has a 2200kv motor and 5.9" tires. On 4s, that's good for around 37mph. With tire ballooning, 40mph is easily attainable. 6s would bring the speed up to ~55mph.

Since your tires are that small, you're gonna have to gear up a little to compensate. With those 5" tires, these are the pinions you'll need:
20T = ~32mph
22T = ~36mph
24T = ~39mph
26T = ~42mph
28T= ~46mph

Those figures don't account for tire ballooning. The faster the tire spins, the more they balloon. Unless your tires don't balloon (taped or whatever) I think the 22T or 24T pinions would be what you want.

Tip: When you enter all your data into the speed calc, and then press the "calculate speed" button, a little gears icon will appear next to the calculated speed value. Click on it and a table will open showing the speeds for various pinions (as long as everything else stays the same).
