The main appeal to the Novak HV system or any other 8th scale system is the high voltage aspect...not necessarily the high power.

Why high voltage?

For a given power level, higher voltage means less current. Less current means less heat.

Less heat means:
+ higher efficiency
+ more durability of electronic components
+ less resistance
+ longer run times.

If you gear your motors properly you don`t have to worry about your reasons listed .

That may be true for 1/10th scale but not for 1/8th scale.

It`s true for any scale .

Wanting to put an 1/8 brushless system in a 1/10 is nonsense and for his reasons shows he must have over geared previously .

I saw buy a appropriate 1/10th setup for your buggy. If/when you get a 1/8th buggy, then look into a larger Brushless system.

Losi has a nice 1/8th scale roller that comes with the motor\ESC as well.

I don't know of many other industries/hobbies that think that ~12V is considered "high voltage" at the system level...especially when talking about electrical systems rated at 50+amps!

For example, I think it's just legacy battery technology (NiCAD/NiMH) and legacy mentality that traps many into thinking that a 7.4V @ 14.8A (110 watts) system is better than a 14.8V @ 7.4A (110 watts) system. Perhaps "good enough" is what we settle for when the track (ROAR) rules stifle progress.
