what i meant when this all started,for example,i just accquired a plane that was an ARF,(no signifigance),that a gentleman had assembled and said was ready to add fuel and fly............let's see,where to begin,well,the guy used all dubro servo horns,they were splined for futaba,the servos are JR! so,it looks like he took his trusty knife and cleared them enough to fit,had one screw in each corner of the servos,plane has retracts factory installed,had a standard jr servo on them,had hacked the plugs up and put in a battery holder with 4-aaa batteries for the recieverpack,dubro control horns,with one screw in each on the control surfaces,and,had plain old 4-40 screws holding the engine to the mount,but,did not feel nuts on the bottom of them was neccesary!i mean,think about it,this poor slob might be flying a plane near you right now! isn't that a little frightening? worst of all,the person made the statement that this was not his first plane,yikes!!!!
