1. What KV is a faster motor. a 3500kv or an 8000kv motor? The higher kv motor will spin faster if the same voltage is applied to both motors. However that doesnt necesarrily mean that the vehicle the motor goes into will be faster. The lower kv motor can be geared higher because it will produce more torque. The taller gearing can make up the difference of the lower motor rpm.
2. When an esc is rated for 6S, does this mean two 3 cell batteries, or does it mean two 6 cell batteries? 6s is 6 cells in series. You can have as many in parallel as you want. could be 2 3s packs in series or 2 6s packs in parallel.
3. Can you run 2 brushless motors on the same spur gear and gain twice the speed, or is there a slight gain with 2 brushless motors? You can run 2 motors and get theorectically get twice the power and hence increase the speed, but... typically this increases the weight of the setup and getting the motors to perform syncronized is dificult and will cause losses. It woulnd not likly be twice the power, but it would be more than a slight increase. You are better off using 1 bigger motor capable of twicew the power, simplify the system and get a better net result.
4. Are there faster and better RC Brushless electronics than Novak, and LRP? Really subjective question. Faster in what? A system porperly sized for the application will yeild the best reults. the novak and lrp are great if you plan to run 6 cells nimh or 2s lipo in a fairly standard setup 1/10. But for sure there are MANY setups that can proiduce many times more power and therefor speed than the novak and lrp stuff
5. Can Lipo batteries explode with out proper balancing? Explode is a loaded term. A damaged or improperly cared for battery can certainly cause a fire. DO NOT EVER DOUBT THIS AS THE GUY WHO FORGETS, IS THE GUY WHO REMEBERS THE HARD WAY. But, simple common sense a basic care and they are perfectly safe. An imbalanced pack can have cells that get damaged from voltage going to high in chargeing or to low in discharging. Either of which damages the cell chemistry and can cause it to self destruct by puffing and in severe cases cause fire.

Thanks, Hopefully your answers will be the same as mine to prove a point.

Ohh and are any of them ESC motor combo's on ebay for the heli's fine to run in an RC18T. This one I dont know and would like to get some opinions on if so and which one? Laters.
