Sanwa have released 2 new servos, the HVS-ZV and HVS-ZS. These extremely strong and fast servos are optimised for both 6.0V and 7.4V and is therefore ideal for use with nitro models, where normally a voltage regulator is mandatory. Double isolated to protect against humidity, and ball raced, the ZV can manage 24.2kg per cm and can complete 40 degrees in 0.08s. while the ZS does 20.5kg per cm and the same range in 0.07s, at 6 volts.
