28 to 30%

[F1 madness]

No dont setup like that
You need to mount all the hardware,radiobox,servos etc mount everything else first
measure and mark 28-30%  on hull then use a piece of dowel or even a broom handle placed crossed ways under the sponsons,place on marks on hull
then with engine,engine mounts,exhaust all fixed together place it in hull move back and fourth till it balances just on the dowel or broom handle 
Mark it then continue to install the engine in that position
You can run either offset rudder or central infront of prop will work either way just make sure the cooling inlets on the rudder are at least 15mm below the sponson bottoms
 
not far from stafford ,if you get stuck more than welcome to pop down and ill help you set it up
I just race with the BMPRS
