    Thanks again
    Will give that a try first and then perhaps see if Santa brings me some brushless motors ๐Ÿ˜
    Cheers

    PS
    At the moment using a single ESC( 20A Mtronics) but would probably go for two if I move to brushless.

    Thanks Jarvo for the additional info...I did Google the safety bag afterwards actually.
    But...given what you've both advised.......as a stepwise approach, rather than discard x2motors plus ESCs plus batteries all at once, do you think perhaps upgrade the batteries first (more power less weight) and re-assess ? Then , if still not satisfactory, change the motors and Escs ?

    Hello chaps.
    I'm very new to this but have just finished scratch building a 46" Vosper Firefloat in the old Aerokits fashion (ie all wood) to the point where I've primered it, fitted a radio and couple of motors (Graupner 600 chosen at random cos they looked adequate!) and a Lead Acid 6v 12Ahr battery.
    Tried it on the local canal today and two problems.
    1: its underpowered...nearly gets on the plane with a fresh battery but not quite.
    2: The battery only lasts about five minutes.
    I'm an old git and don't understand "Lipids" or the benefits of "Brushless Motors" etc and would appreciate any help or advice any of you experienced guys could offer me please on motor/battery choices to get the thing planing and running for more than five minutes.
    Many thanks in anticipation
    Cheers
    John
