For those that are struggling to get their CoG back far enough, there is a very simple way to get it back further, the rudder linkage is what limits how far back you can move the battery.
All you have to do is:-
cut the ziptie holding the servo in,
run a long scalpel or stanley knife blade through the servo tape between the servo and mount,
remove the servo arm,
remove the servo,
clean residue of servo tape off servo and mount with a scrapeing action and IPA,
remove the rudder and file a new flat spot into the top of the shaft at 180 degrees to the original one,
shorten the linkage until the 2 plastic ends are nearly touching each other,
reinstall rudder with grub screw against new flat spot,
reinstall servo the other way round to how it came out with either servo tape and zip tie or glue,
smile as you slide the battery along the flood chamber wall right to the back of the hull!
God alone knows why they install the servo and servo mount the wrong way round at the factory.
Caution, the colour of the motor is not a surefire way of telling the KV as Sailr says the 2600KV is light blue, but so is my 4200KV.
As Sailr mentioned flood chamber venting, i just had to brag on my electrical symbol vents
From bow to stern:-
Danger high voltage.
Ohm symbol,
Caution electric shock risk,
Electrical hazzard,
Resistor symbol,
2 cell battery symbol.
Brushless motor symbol,
Earth symbol.
