Conserver Capable of 3mph and a runtime of 120mins Single Propellor (4 Blade 45mm) Direct Drive to a Electronize 545-12 (4 Blade) Powered by NiMH (6v) 4Amp/h Batteries Controlled Through Mtroniks Viper 15 ESC - Comments: Model Slipway kit of a full size buoy maintenance/survey vessel still working out of Leith harbour, Edinburgh. Maiden voyage took place a week ago, it still needs work to finish it. It performed really well with a very tight turning circle. Further testing shows a more realistic speed using a 6volt power source instead of the original 7.2volts.
