While many models seem to always be tail heavy, others are notorious for being nose heavy. The Great Planes Big Stik 60 is one example. It's possible that the Alpha 60 is the same.

I cut a hole in the bottom of my Big Stik several inches behind the wings and mounted the receiver battery there. It's as far back as a 'flat' battery pack will fit in a fairly skinny tail section. A 'square' pack could go further back but I did not want to buy one at the time. I had to use a servo extension to reach from the battery pack to the switch. I secured the connectors using heavy duty thread (possibly dental floss) because I have lost a plane due to a connection like this coming loose. I just glued the wood back in place, rather than making a removable hatch, and ironed a patch of covering over it. It loks pretty good. It's on the bottom so you don't see it in the pits, and, it is invisible from 50 feet away. Even with the battery where I put it, I still needed about an ounce of lead weights under the tail.
