I've been playing with the idea. I've found several high torque standard size servos in the 5-600oz-in that weigh less than 3oz so a pair would be under 6oz where the Hitec D845 is 8oz. The main downfall is cost, as the high quality name brand standard servos are in the $150-$190 range. Which starts making a single Spekturm 9020 more appealing. Just bouncing setup ideas off the wall.
