Hey, i've got A Hanger 9 Tango 40, and i have flown it 4 or 5 times, and it has worked great, but i took it up to our club's freeze fly on New years day, and it was about 25 degrees and snowing, and when i did my preflight checks, the aileron servoes (JR ST-47) were real sluggish, and worked on and off. then a few days later i tried it again, and every thing works just fine. What i'm tryin to find out is if Servos can freeze, or if the just didnt wanna go that day. Can any body help me?

The reciver battery was probley cold and wouldnt handle the draw of two servos and would go below the shutoff voltage on the reciver. Try and keep the batteries warm, they dont preform well in the cold.

Stick 40

My guess too......

cold battery!

I dont think it was a cold battery, because the elevator, rudder, and throttle worked just fine but the ailerons were sluggish, and on and off, and it wasnt a wire connection either because i checked everything before flight the wing was seperate from the fusealage, in the back of my truck, so i dont think it was the battery
