I decided to renovate a very old model Clyde harbour tug which belonged to my Dad. This has been in the family for over 80 years (Dad would have been 100 this year) and was in need of some TLC. It is now fully radio controlled and runs from 2 x 18650-2000mAh batteries. Length: 41cm, Beam:11cm, Draft: 6cm, weight: 1.5Kg.
