Default First 65cc 3d plane, need help with electronics!!

As title says, accomplished pilot but never have jumped into gasoline aircraft. Just ordered a extreme flight 85 inch gamebird, powering it with a dle65cc motor. Rubbing 900oz torque savox brushless servos and a 10 channel spektrum reciever.

Question is this, hooking up the wiring and powering this plane. I'm gonna have a 2500mah life pack for my ignition on a remote switch. For my rx battery I'd like to run two separate packs as a redundancy. Planning on running (2) packs of 2s 2500mah lipo packs. Am I just plugging these two lipos into the rx? If it's 8.4 volts per rx pack then would I not have 16.8 volts total going into my reciever? Just confused on this as I was told to run 2 reciever packs. Just trying to keep my investment safe all while preventing my rx from going up in smoke.

Thank you all for the help.

When you expect redundancy you should use power box for this type of model, with high torque servos it's not a good idea to run it via receiver! No idea what receiver you use, but some better ones are specially designed to handle two batteries, I use them but only 6V NMHi, so you would have to use voltage regulator unless it's designed for higher voltage. Check the specs.

Dual lipo power set up.

All servos running via Power box.
