i have a heli and the tail rotor will spin right but not left .... im having problems with my silverlit nano copter the tail ...
Probably the best way to learn to fly is to find a group of like minded people locally and ask their advice. ... The tail rotor should rotate so that the blades come 'up' towards the front of the heli. ... My helicopter won't stop spinning! ... still flying awesome but now tail vibrate and it issues backward forward. what should i do ?
I just fixed this problem on mine. The helicopters are not actually set
on channel A. Not sure why it says that on the bottom. They match the
channel on the controller. Here is how: -First turn one helicopter on -On one of the controllers select channel "C" -Move the throttle stick(on left) all the way down -Turn the controller on -Move the throttle stick all the way up and then back down again -When the light goes from blinking green to solid green that copter is ready -Repeat this with the other copter but select channel "B" or "A" instead
For some reason it works better when you start with the higher channel, C, first and then work your way down. Hope this helps!
This issue is the "Drive Gear Unit" It is the small gear just above the motors which is attached to the very large gear. You will have seen several posts indicating that sometimes this gear shifts and does not engage the larger gear. In my case I looked and say that it was indeed trying to engage the larger gear, however the gear is stripped (the teeth are nearly gone). The sound that you are hearing is the sound of the gear slipping against the Bigger gear. I have a UJ365 which is a newer model. To my disappointment I cannot find a "Drive Gear Unit" anywhere on line. The copter will not function without it. This issue is that it takes the lift of both rotors to lift the copter into the air. There are two motors (one for each rotor) and each motor has one of these drive gear units. Each of these attach to the larger gears which turn the rotors. The rotors each turn in the opposite direction. This is what keeps the copter from continually turning in one direction. When one of the "main Gear Units" becomes damaged it seems to have three noticeable effects. (1) There is a noise that is the gear grinding against the bigger gear. (2) Because many of the teeth are stripped the drive gear engages the bigger bear only some of the time, this causes the rotor to turn slower and in-turn causes there not to be enough lift from the rotors to lift the copter. And finally (3), someone noted that copter wants to spin in one direction. Understanding the above, you can now understand that if one of the rotors is not reaching its full potential to turn, it is also not reaching its full potential to counter act the other fully functioning rotor. Thus the fully functioning rotor is forcing the copter to spin in its direction and the malfunctioning rotor is not spinning fast enough to stop the spin.
So this is the answer to your questions, hopefully on the older models there will be parts available for you to replace it. The copter cannot work until the part is replaced.
sir jeremydylan2 you have a problem with your rear rotor assembly. if your rear rotor shaft is broken or the gear is the copter will spin around and around. or, if these parts are not broken then your trim needs adjustment or, you need to learn to fly and control the rear tail rotor so it does not spin around. Thats your answer. firstname.lastname@example.org
I may need more details but is this the way it goes?
1. Turn on the radio, or remote control
2. Turn the power switch in the copter to the on position
At this point, you should see the green light flashing on the control. Simply move the lever that controls your elevation to the full up position and then let it come back down to neutral. The light on your control should now be on with no blinking.
At this point, you are ready to go as advancing that "up" lever again will get that rotor spinning!
The manufacture set it up this way so that you dont accidently "bump" the control before you are actually ready to fly which prevents injury or damage to the copter.
Make sure you're charging fully, until the light on the charger doesn't get ANY brighter when you unplug the helicopter. Also, battery must be allowed to cool 10 minutes after flying AND another 10 minutes after charging. Most crucial is that you must never fully discharge battery. Fully draining a Li/Po even once (especially when it's new) can cripple or ruin your battery. As soon as you are unable to maintain altitude, land copter and power it off. Also, there is a button on the remote, labelled "tail motor speed switch" located near the trim control. With it in the "off" or up position the tail motor is much slower allowing for more precise control. When button is pushed to the down or "on" position, tail motor moves faster giving more tilt, and thereby much more forward/reverse 'thrust'. Verify that tail rotor is moving when right joystick is actuated (and that it reverses when right stick is pulled in opposite direction) and that it isn't loose on it's shaft... this can be tested by verifying tail rotor spin in one direction then reversing joystick... tail rotor should instantly start spinning in the other direction with NO hesitation, if it slows and then starts spinning in other direction or anything like that then it's loose. Turn helicopter upside down then VERY CAREFULLY apply a small drop of super glue where the shaft meets the tail rotor, be very cautious to not get any glue near where the shaft comes out of the motor, and do not turn right side up until glue is fully dry.
This problem can be especially confounding because the way the copter distributes torque on a slick floor can be a spin opposite to what you see in the air!
The solution is to get the machine in the air quickly and make your trim adjustment based on that. The tail rotor is very sensitive as you know so you need to be working that stick constantly to acheive trim, this is part of what flying an RC copter is all about. A four channel copter is much harder to fly but your dragonfly can prepare you for this.
This is a two channel Dave, meaning that the radio is only capable of up or down, or to spin the tail left or right. You will get forward momentum out of it because the design of parts like the removable cockpit housing, or the weight of the battery pack way out front give it "ballast" for forward momentum.
This is very similar to the way the small indoor models work. You will need to get the copter trimmed out to see this happen. Keys to stable flight are to stay at an altitude that you prescribe,
Have you tried checking the back tail? It comes down right under the rotor. If it is ripped, DONT TAPE IT! Taping will just ruin the weight balance and ruin it. If it is ripped, return it and exchange it, dont try and fix it.
