RE: 1/4 scale Gas Tunnel boat ... what to build?
Hi Guys
some awesome news. Yesterday we ran 70mm and 76mm carbon fiber props ,full size ,with our new batch of cables, without any regard for throttling off in turns etc. I had a SIG mounted on the leg(some extra power) and Tikie ran his Zenoah (Awesome boat). We left the Dam at 2pm without a broken cable. We will be at the dam on Saturday to run our new season boats and to prepare for the race in the States come March.
A word of warning. Do not run a motor without an efficient air box. I ran a new ZIG without a air box and the water spray being sucked into the carb actually damaged the piston on the carb inlet to a point of "NO compression". It seems that the cooling effect of the water on the side of the piston distorts the piston which causes excessive wear.
May you all have a great 2008 and we look forward to a great year of seeing the gas boats establish there class after all these years of R&D. well done to "ALL" who have added there bit to the equation.
