hi. i dont post much here, but read all the time... anyways i have an art tech cessna 182, when i fist got it, i could take off no problem from the ground, lots of power, on the stock pack and the lipo.... i flew the plane 3 or four times only, and on the last time, i broke a prop, and didnt fly for a couple weeks...

i tried the other day, i had fresh charged batterys, i tested em with a voltmeter, the plane just will not take off, the best it got was 2 feet up the the tail hanging horribly till it flipped and broke prop (again) and wing..... fix wing no problem, put on new prop and still the same. seems like there is 1/2 power or a little better, i checked everything over 6 times..... motor shaft isnt bent, although it seems i can pull it out a .mm or so, push it back in the same.

could it be my motor? esc? my battereys have been charged/discharged 6-7 times only, im sure there good. oh i also added deans ultra plugs to both batts and plane.that should make things better, not worse.

any help appreciated.

Most likely your motor has been damaged.

You can test the ESC as follows: Take the propeller off. Using a voltmeter, check the voltage coming out of the battery. Then check the voltage at the motor where the black/red wires are attached with the control at full throtle (the motor will run). If it delivers the full voltage provided by the battery then the ESC is working properly.

By the way, these motors are cheap. I think Parkflyers.com has them for $19 for a set of two.

Hope this helps.

thanks for the reply, ill check voltage at motor tommorow. thats gotta be it. ill see if i can motors around here, i went to the nearst city around hers hobby shop. the kid didnt know what a 480 speed electric motor was. he gave me some 150.00 motor for a car.i told em , na.... i dont thinks so, they should be 20 buks for 2...... oh well.

This mutiplex motor is a good fit for the Cessna:

I had bent shaft so i needed replacement. I got mutiplex because I had good luck with this brand in the easystar plane i have. Just be sure you get similar weight as the stock motor so you don't mess up the CG.
