Once you put the training gear on you'll probobly have to rebalance the heli, this is usually done by repositioning the battery pack.

If you've never flown an R/C heli, or tried one on a sim, I would suggest buying up some spare parts. Take a look at my Before/After thread to see why, all that damage was done just from the blades getting caught up in some tall weeds when landing, which caused the heli to flip over and "self destruct" [&:]
