Ok Guys I took up my tower hobbies series 40 up and the plane keeps getting hits real bad and the engine dies after about 3-5 min into the flight I have a OS La 46 engine in it So since I am new I fig I would just Change the Engine b/c it has a real bad rattle maybe the bushings are going out I dont know and Change the Reciever Since it is Getting Hits all the time! So What reciever and what engine would work good in it. I have a Futaba 4 channel Skysport remote Any Suggestions? What I should do!
