can speedpassion reventon pro 1.1 power up HV servo?

can anyone help with this question? I have a speed passion reventon pro 1.1 using KO 413 receiver, can this combination run High Voltage servo at 7.4V?

just found out on instruction book that the max out put from is 6V...

You can.  But need to do the following:

1:  Remove the red wire from the esc to the receiver.  (Make sure you isolate it so it will not short with anything)
2:  Connect the battery +ve and -ve to receiver.  It is a good idea to add a switch so you can turn it off.

Now it will work with your high voltage servo.  

thank you for your detail explaination
