Built as a rescue boat, the Springer seemed to be the easiest to build as I am still a Novice and to while away the time after my knee replacement. Blew up some plans off the net to 23" length and 10" beam. Makes her about 1/12, I think. Built from 3mm ply in the main. Powered by the LRP 12v Truck puller and direct drive via 12" ball raced prop-shaft with home made oiler and 50mm 2 blade propeller to be changed to 3 blade asap. Led lights front, back and upper. Transmitter Turnigy TGY i6, Rx TGY iA6, Esc 320 amp with fan. Ballast yet to be added and should slow her to scale speed. interesting build had some problems with upscaled plans from a pdf. Goes well in the bath but will post video as soon as I can get to the water. (Motor: LRP 12v Truck Puller) (ESC: Chinese 320A with fan) (7/10)
