Mini Rio Newbie Qns

[doggie]

Just got my hands on my mini Rio yest. Upgraded to brusless with this set up:

Hobbywing Seaking 35A
Align 400 size 2700kv b/l
stock prop
3s 1300mah Lipo with deans

Boat still had the issue of getting on plane .. moreover it kept self turning to one side irregardless of trim . kept havin to counter steer to keep straight , is it coz of the batts n weight balance of the boat? ... it's only after a few correct turns or keeping it straight for abit than it boat catches on plane an starts zooming away at an amazing speed .. is this normal for boats ?

sorry guys it's my 1st foray into RC boats .. soo I'm just v v lost .. feels my boat is too heavy at the back . mounted the RX there ... esc weight is rear bias too .. should I move it more to the front hatch?

Any advice on changing the props soo that it's easier to get on plane immediately ?


regards and thanks guys
