everything is good excepted the servos, to me savox is the perfect example of an overrated brand
let's put it this way: they're good when they work but their endurance is poor.. never managed to make a savox servo last more than a year and a half.. it just never happened, and I tested MANY
as a side note we race in all weather conditions including 12 hours races so we put more stress to them than many would but trust me savox is "cheap" for a reason.. there are no good servos for that price IMO you need to put more $$$ to get something that will last.. the closest that is really good is ace and hitec.. if you have more money sanwa, futaba (especially the brushless ones) or even kopropo will last forever
savox are all about the specs: speed and torque but they aren't efficient at all they are noisy, less precise and much more power hungry than the other brands I mentioned
too many people go crazy about speed and torque but what REALLY matters is the precision and this is not given with numbers, compare a 1258tg to any futaba brushless available and you'll see what I mean
