Status: offline 		My Ultra Stick .40 is almost ready to fly. I did put a nice Enya 60 on the nose (2 stroke). It weighs around 15 to 20 ozs. Should I use a 4.6 1100 mah rcvr battery? Or maybe a 6.0 rcvr battery? I have heavy duty BB hitec servos in the wing. I'm hoping the battery (mounted near the tail) will take care of most of my weight issues. Should I go bigger on the battery (1400 mah)? What did you guys do that mounted big fat motors on the front?

Status: offline 		I fly mine with a irvine 53 and a 600 ma 4.8v pack and it flies great lasts at least 3 flights, i had one so i used it, a 1100ma 4.8 is what i would have used there is very little weight difference on the aa packs, if you think you might need more tail weight you could get the 1300 ma sub c pack and mount it more rearward, they weigh about 2 oz more I had no cg issues, my irvine weighs a little over 17 oz and the battery pack is in the rear wing area of the fuselage

Status: offline 		I have a saito .72 on mine.i put the servos for the elev. and the rudder on the tail infront of the vertical fin.Put a pull-pull on the rudder and used a lead shot weight to balance it.I it mounted on the tail wheel and mounted a square 600 mah 4.8v battery where the elev and rud servos were. balanced out pretty nice. And i used 3/8 sq. bass wood to mount servos on the tail,used epoxy to glue them in.

I'm ussing 3003 futaba servos and the 4.8 v, 600 mah batterry.No problems with the it.

Status: offline 		Did you mount them "in" the tail or "on" the tail? Are you running all 7 servos? If so the 600 mah battery is enough for more that few flights?

Status: offline 		Yes i am, running 7 servos,the rudder servo is ontop of the fuse. about 3 inches infront of thr verticle stab and the elev servo is just behind the rudder servo on the right side of fuse.
I usssually do 2 or 3 flights then use my quick charger to recharge it.I ussually charge when my tx batt. goes down to 9.5 volts.I have a 12oz fuel tank.You'll have to do the math.

Status: offline 		Got it. This may be off this thread but my crow switch is occupying my D/R switch for the elevator. Did you guys figure out a work around or do you just not use the D/R on the ele? I set the throw in between the hi and lo suggested measurment and put an expo of -35 on it (Futaba UHFS).

Status: offline 		I have the same problem with the loss of tht elevator D/R switch... There is a thread in the radio forum that receommends changing the D/R switch to another switch or ganging it up with the aileron D/R switch. I haven't yet tried this. So far I have just been dialing down the ATV to get the elevator where I want it. The controls on the US are surprisingly effective so a lot of throw is not required. The rudder is very strong -- I have a free castering tailwheel on mine and have no trouble taxing around on just rudder.

Cheers!

Galen

Status: offline 		same with my futaba 8u, low rate elevator is 100% with about -30% expo to soften the middle and hi rate is crow mode on mine, have fun. you will have a rocket ship with a 60 on there, mine hovers easily and flies fast with the irvine 53 and a graupner wide blade 12-5
