ALL OF IT LOOKS GOOD TO ME AND YOU WON'T NEED GAS. I'VE GOT A SAITO 1.80 ON MINE AND SHE'S A PLENTY. I THINK YOUR CHOICE OF SERVOS ARE PROBABLY OVERKILL THOUGH UNLESS YOU PLAN TO 3-D ALOT. I USED DUAL ELEVATOR SERVOS ON MINE (HOBBICO CS-65) AND THE SAME ON MY AILERONS. THE ONLY HI-TORQUE SERVO ON MINE IS ON THE RUDDER (HOBBICO CS-70) AND THEY ALL SEEM TO BE MORE THAN ADEQUATE FOR EVERYDAY SPORT FLYING. I DON'T DO ANY 3-D FLYING SO ALL OF MY GIANT SCALE PLANES ARE USING THE EXACT SAME SETUP. FROM MY TEXAS HURRICANE WITH A G-38 TO MY ULTRA STICK 120 WITH A SUPERTIGRE 3000. AND THEY COST A LOT LESS THAN HIGH PRICED DIGITAL OR HI-TORQUE SERVOS. BUT THAT'S JUST MY OPINION AND EVERYBODY HAS THEIR OWN PREFERENCES. HOPE THIS HELPS!
