Thanks Rowen. The model is a Tamar Class Lifeboat. It is 1M long by 320mm beam. The supplied props are 40mm diameter although the kit designers say these are slightly smaller than the scale size. Peter.

Have tried both and out runners are more suited to driving water propellers. Hobby king have several water cooled ones available and water cooled mounts are also available. The water cooled motors seem to be adequately cooled with even slig …

Out runners are the way to go, as size for size they have more torque. Inrunners are more suited to high speed race boats etc. For cooling to you could either fit a small fan (on the motor shaft or separately) or use a water cooled motor mo …

Hi DodgyGeezer, Thank you for all of the information. I understand this a little bit more now. I see many models hammering across the water but I like to see more scale speeds. So would you say that if you made something like my HMS Cottesm …
