I love you too Bob…..
I believe Ron`s Titanic is a largish boat, and may well require gears on 540/1 motors (assuming the lower powered MFA types) as he is suggesting.
To be honest, a duo of MFA800 motors and a 540/1 for the smaller centre prop all running on 12v might be more appropriate? If ,as its a larger version to mine is anything to go on, you wont need many revs, and an 800 lightly loaded will only sip at the battery.
As you say Bob, who wants all those gears? (this from a man who has introduced all sorts of extras on his current build!)
