Here are some picks of my Backlash build. Built the boat last spring and had planned on running my home modified Zenoah but had a change of plans, I am now going to run it with a RCMK K-30. I have one stock out of the box (red cooling cap) and one Motorheads RC modified engine (silver cooling cap). I am going to run it first with the stock engine and get the boat setup correctly and then try out the mod engine to see how she go's. I think I am gonna need some bigger props! Stay tuned
