JR equipment on 6 volts???
Can all JR Rx's and servos operate from 6 volts without any modification? What are the advantages of 6V as opposed to 4.8V?

RE: JR equipment on 6 volts???
A good question, and the answer depends on where you live and where you source your servos from. The receivers are happy enough to work on 6V BUT Gyros are NOT designed for 6V and have to be run of 4.8V.
What I have found so far is that JR (Japan) manufacture a series of servos the majority of which are designed to run on 4.8V. However, what they also do is manufacture a whole load of servos for Horizon Hobby in the USA (which some people also call JR !!) and these can be run off 6V.
Do you have any particular servos in mind ? If you know which ones you are getting, then if you look at the JR Wings Catalogue ( http://www.jrpropo.co.jp/radio/jp.html )you will see if the servo is a standard JR or if it doesnt appear in that catalogue, then its a Horizon special.
Main reason for running 6V is extra speed and torque, usually a 10 - 15 % increase in both. The dangers of running a 4.8V servo on 6V is that it may shorten the operating life of the servo. Should the servo stall for any reason, then obviously there will be higher stall currents with the possibility of damage to the servo motor / electronics.
