Many thanks for all the suggestions! The battery pack indicates it is a high output pack.
I don't know what this means as far as discharge amps, but I would assume it should provide at least 20 amps. I don't have a way to check amp draw. The center of gravity
is exactly 1/2" in front of the molded in C.G. marks. I'm going to go out now and play with the battery position. The plane just glides in to a nice landing when launched. My
initial thought was I had a bad pack, but I switched them out, added some up elevator trim (too much) and it stalled when launched. My packs are made from AA cells. Sorry I forgot to include that! I also wondered if the prop was backwards, so I switched it.
Didn't change much. Thanks again.
