I have a four star 60 ARF that I put together and am now at the balancing stage. With the battery right behiend the fuel tank and the receiver directly behiend that it is going to take approx. 6 3/4 oz of weight by the engine or 5 1/4 oz at the spinner. I am pretty new at this still but that seems like a lot of weight to me. Has anyone else ran into this or have some suggestions? Should I just put the weight on and go with it?

Thanks for the help!
Matt
