Thanks Tim. Did you notice the breakaway wooden waterpickup rudder?
The drive line and engine is what I cant decide yet. I wrote Bill Hughes
about the GZ. His response was this..
" It is NOT a Boat Engine. It was designed for use in a Model Airplane. A Control Line Speed
Airplane. It has shown that it does not Throttle down very well." He then went on to say it was used in a RC tractor with a larger cooling head he sent a pic of.[sm=confused.gif]
Im disappointed because the GZ prop screw is a 4M (instead of the 3M norvel) from what Bill said. Which could be replaced with 4M threaded rod. Then lathe the hole on the flywheel to 4M and attach with nut. The threaded rod after the flywheel nut could be turned to 1/8" to mount a set screw octura .098-1/8" flex hex.
Now what? Back to the norvels and deal with the 3M screw?
Or still go with the GZ engine despite what Bill said? He sent me a price list which shows a tuned pipe for $25. Why wont it work on the normal timed engines? He also has a heat sink head available. Why would that be available if the engine was strictly for airplanes?
And others have said use a exhaust baffle on CL engines. Which would work better? The carb or baffle?[sm=confused.gif]
