I am thinking about using a pull-pull system for rudder and elevator. That would elimainate the tube and the wire extensions. I will balance it by moving my abc .51 on mounting rails. If I can get rid of anything else....I will ....to make it lite. Maybe leave landing gear off and land in tall grass!!! Well...the project begins. ANY Ideas??? Thanks Capt,n UPDATE.... do not need the pull pull....it flys great now
