7.4v servo wiring

[tomtom]

Hello,

I've just bought a used KO RSX. I used a KO 2413 with a mini Spektrum receiver (3500) for electro offroad. Without plugging the cap on the receiver, both are working without issue (got an Orion and it needed the cap).
Still, the RSX seems power hungry so I thought about powering it directly from the saddle lipo by cutting the red wire on the receiver side and solder it to the + of the esc.

Does it sound right to you ?

Any advises against doing so (7.4v power) ?

I planned to use this wiring to avoid any glitches from the servo at full throttle.

Thanks !
