Where to put all the radio gear

[madcrazybonkers]

Hi all,
Have seen a lot of pix of Losi mini 8ights where people try really heard to mount all electrics on the deck is this just to get all the weight as low as pos or to help with the balance of the car and does it really make that much of a difference.
I checked all my corner weights today and they are all over the place in standard electric install would i be better off getting all corner weights the same to balance the car out or again would this make any difference.
Never have been much good with setups and since returning this is one area im really trying to learn.

Cheers Mark
