Hi unbuiltnautilus
Many thanks for the advice - I learnt that mistake on my Dreadnought being powered by 12v running these motors and my God, what a vicious little buggers they were ripping the motors from the mounts!
Steve had some common sense deciding early on to use 6v SLA and has stuck to this plan.
Speed controllers should be here by Friday ready for sea trials hopefully this weekend
Hi Sandy
I'll get the measuring stick out later and measure them but I think they are either 35 or 40mm diameter.
I'm sure your beauty is realistic enough as I can't imagine that the TF's were particularly fast or brilliantly manoeuvrable.
