Default ESC problem or motor?

Very basic stuff here. I have a little Calypso Micro. I charge the battery. Reads about 4.2 but it wont fly. It just kind of settles to the ground.I cant get enough thrust? Motor not spinning fast enough? What could be wrong? It's been ok until now. Havent had the plane very long. Thanks..

By chance did you have the prop off and put it back on backwards ?? ENJOY !!! RED

It's almost impossible to put the prop on backwards as they are spring-loaded to fold against the fuselage.

Does the prop/motor spin freely by hand?
Did you have a crash ?

Without more info, my guess is that your battery is failing. Even though it charges up and reads 4.2 volts it probably doesn't have the discharge quality anymore to deliver the power required to fly the plane.

I've had many crashes. I repaired the body and when I tried to fly after the repair , I had the problem with not enough power. I'm thinking it has something to do with the battery too although I've tried different batteries. The motor does make a certain amount of noise. Could be some of the glue got into the motor.

Check over your fuselage. I had something similar with my Apprentice. After I crashed it and replaced the cowl and motor mount, I couldn't get it off the ground. It would get up to speed and I would give it some elevator to get it off the ground and it would just stay down on the gear. Turned out that the fuselage was cracked just in front of where the vertical stabilizer mounts to the air frame. It would flex when elevator was applied. Check for cracks in the fuse.

The motor making a new noise is probably your biggest indication of what's wrong. You could have bad bearings, or the shaft could be bent, or maybe a magnet got knocked partially loose. If the problem is causing extra drag in the motor, you'll burn up your ESC soon too. Does the prop noise sound like it's a lower pitch than before? If so, you probably need a new motor.

OK, now we have the whole story.
The motor has probably been through a lot and more than likely has been damaged. These micros are tough but constant crashing will take its toll.
The motors aren't that expensive. Buy a new one and replace it.
