Swap over the two wires that go from the motor to the speed controller. NB. don't swap over the wires at the battery this will destroy the speed controller.

SOURCE: heli max hicro helicopter just keeps spinning in circles

Make sure you used the right blades, the top and bottom blades are different parts and if you try to replace an upper blade with a lower blade it will mess up the flight. The two sets of blades are reversed, the leading edge is on the opposite side because they spin in opposite directions.

If you are sure you have the correct blades, try to eliminate vibrations, especially in the upper rotor. Vibrations can throw off the gyro sensor and cause the helicopter to spin. If it isn't vibrating then you need to adjust the trim. If it is just a slight spin, you can try using the horizontal trim adjustment on the left stick. If this is not able to correct the spin, set the horizontal trim on the left stick to center and then remove the plastic canopy. On the circuit board you will see two screw adjustments labeled "SENS" and "SCALE". First, draw a mark on both of them with a marker making sure to touch both the screw and the plastic or board. This mark will be used to reset the knobs to their original positions if you mess up. The "SENS" (sensitivity) knob adjusts how hard the helicopter responds to the gyro. The "SCALE" (rotor scale) adjusts the balance between the two rotors. If it is a smooth rotation (as opposed to a skittish, jumpy, or erratic rotation), you need to adjust the SCALE knob as one rotor is consistently faster than the other. On the other hand, if it is erratic and jumpy, randomly spinning in quick bursts, you should adjust the SENS knob. Erratic spinning is a result of the gyro detecting vibrations and overcompensating, throwing the helicopter in a circle. Play with these knobs, try just slight adjustments and keep going until it flies right. Have common sense, don't turn the knobs too far at once, just small adjustments will make it easier. Also if turning the knob one direction makes it worse, go the other direction. If you turn the SCALE knob too much you may lose lifting power because it will reduce the maximum power of one of the motors.

SOURCE: I recently bought a Walkera 43g heli with a 2801

This sounds like low power on the receiver BEC or the transmitter battery power. Check the voltages and cell polarities. You should not be getting interference with the 2.4 G system. If this is not the problem then I would send it back.

SOURCE: i have an apache 3 channel helicopter.the top

Same problem I had. There are two motors. One to spin the top blade and a second to spin the bottom. My motor was defective out of the box to spin the top blade. Very poor quality as my AH 64 had a bad circuit board. I had to take parts from one to fix the other.

My upper rotor does not always power up when i throttle up on my walkera 5#10. i have replaced motors with new factory motors thinking that was the problem but same problem

Hi, I had this same problem but its my bottom rotor that wont throttle up. Before you bind put the throttle in full. After it binds return the throttle to min. and its ready to go. I hope this helps, although its not a fix. It a cheap one $$$.

Walkera lama 400 just spins round

The walkera Lama has a bad gear setup,there are two tiny screws on the top
gear which powers your bottom blades one on each side of the outer shaft
if these two screws were not properly tighened at the factory or you ran yourLama
400 into the ground even if it was at a slow rotation when the bottom impacts
the ground the bolts shear off the outer shaft and you no longer have 100%
power to those blades,if your helicopter spins clockwise and you tried every
thing,this is the problem,replacement is required or you can tear it all down
and drill and tap two new holes with new screws,these are machine screws
and are less than 4/40 which is very small.To check hold top gear with two
fingers left and right side of gear and turn the bottom blades only,if the blades
turn your shaft to gear screws are sheared off

good luck

Help....we poured some water into the bean grinder/container


You have to take off the bean hopper, turn the ring on grinder anticlockwise to you see the claque. Take out the middle off the grinder and clean everything carefully.

After that you have to put it back again, when you have the middle off the grinder back you turn the ring clockwise to the end, after that you turn it anticlockwise 14 "tick".
