I have a Kyosho AT-6 still in its box. The nose of the AT-6 is very short (after all, it's almost scale) so care has to be taken to minimize the amount of nose weight needed.
I have seen a Saito 56 powered Kyosho AT-6 fly. In order to minimize the weight the owner had moved all radio equipment as far forward as possible in the fuselage. Also, he had put the Rx battery on a shelf that was attached to the firewall inside the cowl. Apparently these modification did the trick as very little extra nose weight was needed and the aircraft flew in a very realistic manner. I plan to assemble my AT-6 in the same way.
