- You could knock off 2 packs of batteries by going with only 1P. Some Speed and Reliability will be sacraficed. A smaller prop must be used. As far as motor goes, you should be able to get away with a NEU 1527 around 1000kv on hulls in the high 30's to 40"

1) I always wondered the same thing. Electric motors can turn higher RPM, produce more power in some cases and operate at a much greater efficiency level. Electrics will continue to improve as these latest and greatest motors have only been introduced in the last few years. Gas / Nitro engines have been around forever and there is not all that much room for imrovement. ( Personal Opinion )

2) Different winds produce different kv's. Kv stands for how many revolutions per minute the motor will spin given 1 volt of energy. A 1000kv motor will turn 10 000RPM given 10v. The key here is this is unloaded RPM and will drop 70-80% when under load.

3) The hull is completely sealed unlike gas or nitro hulls. We tape our hatch shut and the hull becomes water proof. If however water does get in, the ESC is water proof, the motor is usually not harmed, and the packs should be dried out. Receivers and servos usually recover after being blow dried with hot air.
