Actually the ESCs for the motors are Hydra 15s. Found here: http://www.mtroniks.net/details1.asp/ProductID/194/lockit/true/G2-hydra15.htm The motors are Turnigy SK3 series this is the page: http://hobbyking.com/hobbyking/store/uh_listCategoriesAndProducts.asp?cwhl=XX&idCategory=664&v=&sortlist=P&LiPoConfig=&CatSortOrder=desc I used the 2822 1275kv motors for propulsion on 3 LiFe cells (9.6v). They are mated to standard ratio BC gearboxes. The radio has adjustable end points to dial in the speed. It is a good combo of power and efficiency. It was built to be optimum not cheap. The pump motor is a 4000kv+- Scorpion motor on a planetary gearbox. It is experimental. Initial tests were positive. I was running it as a 1unit pump on a modified large pump. All of my choices factored in the voltage choices I made, long run times, and performance.
