    hey daz,have you looked at the REK lowers,not as nice looking as the OS but composite so both would probably weigh less than one OS, probably cost less to buy 2 reks than one os as well.
    just a thought as there would be a lot of weight in the a$$ end
    lol just looked at the size 40", should be ok with that power having a bit of weight,check prop size as most legs are limited to prop with the cav plate on

    option 2

    Doing abit more research LOL
    what about this set up:
    2 x OS outboard legs
    2 x Scorpion 4025,890kv,8s,2700watts,95amp
    2 x 200amp ESC
    2 x metal geared hi-torque servo,running twin links to each Ob and linked together
    2 x 51mm 2 blade props L/R
    4 x 5000,30C+,4s.2 running in parallel to each motor
    which option do you think would be better
