Hi everyone, I am still in the process of building my Perkasa 49" and I would like to use electric in her when she is finished, but I haven't got a clue on how many motors I will need or what size, also what size rudders should I fit, what size propellers and propeller shafts should I use, what kind of speed controller and radio gear do I use? This is the first time I have built any kind of remote control model, so any help would be very much appreciated. Thanks in advance.

Dave.

Hi Dave, welcome to the forum....
Right where to start... How fast do you want it to go? Scale speed? A bit faster than scale speed? Or screaming across the lake like a banshee!!
I have just the motor(s) you will need, have a look at this link http://www.youtube.com/watch?v=fp3RNTVk1z4
This is a 49" Perkassa using just 1 (one) of my MMB 900 motors running on 24 volts, it ran for approx 45 mins on one set of 4300mah Nimh stick packs and a 55mm plastic 'X' prop.  Here are the specs of the motor http://www.modelboatmayhem.co.uk/forum/index.php?topic=19292.msg187412#new
