Buy the way I have a saito 82 in it. And is their any advantage if I add the vecolity stack from the G.K. to mine will it make a difference? It only cost $7.00.
The velocity stack will direct the fuel spitback that come out of the carb back into the motor. The result is a cleaner engine bay and better fuel economy. You will be able to lean the high speed needle with the stack installed.
I think 4lbs is probably the X50's bare airframe weight, 6 lbs seems to be the normal AUW.
