that whole setup look slike the dang thing is not going to run liek a bat out of h e l l , it looks liek its going there....i have a feeling if and when he tries to run it...we get the thread called "double engine gone bad" or in his case and spelling" dubble engine gone bad"

anyways u are going to need metal gears, i cant stress that enough....any gear u may have, it better be metal...also the power thing between the two engines will most likely kill ur two engine dream, i dont see how two different engines with different power ranegs are going to run together

ps have fun with tuning, and getting it to work properly
