Ihave the Easy Hawk, and absolutely love it. I've done some minor modifications to the second one Iown including additions to the rudder and elevators to give them more effect. I also put a slightly larger but thinner prop on, and WOW what a difference the prop made.

I am not having luck however with getting another battery. Any idea where Ican get a 8.4 v 1300 mAH ni-MH replacement? Thanks so much.

It sounds to me like you have an old 7 X 'AA' pack.  New 'AA's can be found up to 2450 mAh, so chances are that any 7 cell 'AA' pack will be roughly the same weight but with greater capacity.  Watch out for the configuration whwn ordering one, because you can get either a 'flat' 7 cell or two different styles of  '4+3' configuration.

Hi Bruce,
Thanks so much. It is the old aa set, with 4 and 3. Can the Wild Hawk handle a battery with more mAh? I'm pretty new to the RC world and don't want to get something that will fry the plane.

No problem using any battery capacity; you could use a 5000 mAh pack if it were light enough!.  The only effect of a greater capacity pack is more weight and/or longer flight times.  It's the voltage you need to watch as too high a vottage can pump too much current through the motor, compromising the ESC, the motor, or both.
