Doug,

My slightly lightened stock 60 is running, you guessed it, a Saito 72 and at 6 3/4 lbs it does all I ask of a stock 4*. My heavily modified 60 is running a Saito 100 and and at 7 lbs has totally unlimited power. My 120's are both modified and they are my favorite 4*'s. One is equiped with a Saito 180 and scales at 9 1/2 lbs the other is equiped with a RCS 140 gasser and scales at 11 lbs. Both have totally unlimited power and are absolute blasts to fly.
