Hey jjvanwingen,

Definitely get extra sets of blades. The ones on this heli are thin and can chip fairly easily. And the blades are VERY inexpensive (I think like 4-5 bucks for two sets). E-flite makes a heat sink for the motors that can be easily installed by yourself. You can get all this stuff from Horizonhobby.com. If you have trouble finding the items using their search engine (the battery for instance), go to E-fliterc.com, find the part, and then click on Buy It Now. This takes you directly to the item on Horizon Hobby's site. The E-fliterc.com website has a lot of great info as well.
