went out to fly tonight, and noticed that it didn't seem as loud as usually, or rotors spinning as fast. but it still lifted off ground and i took off doin a little FF, and then after about 3 mins, i lost alot of power and quickly landed it. i thought i had ruined battey or something and hit voltage cuttoff, but ran inside and got voltmeter and battery still read 11.30 volts. now motor was hotter than usual, esc is always kinda warm, but seemed a little hotter than normal, also battery was pretty warm, but always is. so i let it sti for about 3 -5 mins put in another battery and still seemed not right sound wise. also i noticed it was tilting alot more to the right than normal. so i only flew for a min, and landed. took everything inside, and belt is not overtight, everything seems good to go, and no binding. i decided to spool up again in house, but not lift off, and noticed the blades looked way out of track, so i spooled down( i knew they couldn't be that far off without something broke) but when blades stopped spinning, i looked at blades and some of the tape i had on the end of one of them from balancing, had half way peel off. so my question is, can the tape hanging down like that make the motor and esc hotter than normal causing thermal shutdown? and also making it tilt more than normal? i would test it out, but it was getting dark when i was flying so now its dark outside.

your batery may read 11.30 volts but if it is placed under load it might read alot less
the tape might have been the broblem but i am not sure to tell you the truth

went out first thing this morning, and everything was back to normal, sound and flying time. so i guess it was the tape causing enough drag to overheat everything LOL

I was trimming a plane for level flight and I was using the wrong technique. I was adding little bits of ballast to the high side. My LHS guru showed me the right way.
Note that this is on a plane with a lot of wing surface and little wing loading.
He took a piece of tape about 1/2" wide and applied it to the upper surface of the wing, about 2/3 of the away out toward the tip. He folded the tape into a little "Spoiler" about a quarter inch wide. All it did was "spoil" the lift as the air flowed over that part of the wing. The plane was still off balance by weight, but he balanced the dynamic lift perfectly.

At the speed the rotor blades run, it seems logical that the tape flap would cause the problem you describe. I know, you already did the test, but again - the tape acting as a spoiler seems logical.

Still building the mental database.

Scooby,

My bet is on the tape, you noticed the difference in flying conditions.. Take the tape off. Start fresh and rebalance the Blades to perfections and you'll be good to go. Just a small hunk hanging there will cause undo wind resistance. Yikes!
