Servo Board

the receiver he's talking about (planet 5) WILL blow on 7.4v

The heavier one seems to be capable of going to 9v.

Usage I suppose depends on wether the mods to enable the current setup to run a higher voltage weigh more than 0.5 gram.

Oops, didn't realise they more than 1 planet 5 rx!

I've already been running my planet T5 at 7.4v
The original servo board I was using was a HPI SF-1 as I stripped the gears.
Would the Futaba S3003 work on 7.4v?

That rating on Spektrum RX's of 3-9v is bull-poo, I've known people blow them up trying to plug a lipo into it.

When I helped make a 3-Servo lipo ant, I had a voltage regulator that stepped down 7.4v to 6v and powered the receiver, the positive wires from all 3 servos went in before the regulator chip (FET). Spektrum RX's may struggle with that unless you have a large battery and a high rated FET, the one I used was 1.5A.

Thats a big battery for a RX battery
I have a Simon Windisch design voltage regulator, I'll use that to kepp the volts down.

As a very inexperienced roboteer i hooked my planet 5 up to a 9 volt battery and I broke many servos but not the RX, I was using duracell rechargeable batteries btw.
