stearing servo

[ryanvm777]

I finaly got aroung to working on my money pit/Emaxx. I installed a hightec servo. How do I conect the arm from my servo saver to the servo? All of the holes are to small. If I use the stock round thing-a-ma-bober that is conected to the servo and drill a bigger hole it will not pull the arm far enough for full turning. Do I use the one that came on the stock servo? It dosnt look very strong.

Also I will be buying some lipos for it next month. Its been so long I forget what I was supost to get. Right now I am running 18 gp3300. I think I was supost to run the lipo parrallel. But I dont remeber. I want about the same amount of power but alot more run time. What configerations of lipo's do I run?
