i've gone over the motors from the first page on this thread. i'll go over it again
The prop adapters are built onto the motor bells. if you crash (and you will) and that bends it's a $23 motor to fix it.
they got some problem with soldering over there.... dji gets rosin all over the connectors on the motors. it intermitently makes a motor loose contact and the model flips to it's death. if your 2 feet up over grass it'll break a prop, if it's way up and hits something hard, it'll smoke alot of parts
There only 120 watt motors. it is great at lifting as it's sold in the arf box, but you start adding anything to the model they become underpowered quickly.
There alos not smooth at all. Power up the midel without a prop and drag your finger nail across the bell while they spin. You'll feel alot of vides.
Whats wrong with vibes? well it makes jello but more importantly is the cause of a flyaway scenario where the models motor vibrates so hard it throws off the dji algorithym to the point nothing you do means anything. it just leaves.
wasn't yelling at ya, just keeping you informed of the downside to your choices...... you can sell them motors to some unsuspecting customer.
Tiger has a cheap 2216-900 for $25 a pop. Best value but only up to 3s.
