If you're going to order thru Tower hobbies their computer system will have the part numbers of all the items neccessary to finish the plane.

However if your not sure battery you will need or other item maybe you need more research before buying.

Do a search on towers web sight look in the product notes and tech notes more info can be found their sometimes..

Also again this website has a forum dedicated to electrics also I've said this before to check at ezonemag.com all they do is electrics if you can't find the answer on RCU Ezone might have it..
