RC Remote Control Helicopter Ready To Fly - Answered Questions & Fixed issues
Hi,
I have a Walkera CB180d
The gap is causing you to loose power transfer. Replace the main gear and you should be back in the air. The CB180 is a fixed pitch, so as long as the blades are intact and straight, you can't do anything esle to them. Also make sure your battery is good and fully charged.

My helicopter won't take off,
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.

Yiboo UJ4708 will not lift even after being fully
i had the same problem.. one of the gears isn't fully engaged.. if you look at the internal mechanism, you'll see two small gears on opposite sides, each engages a larger gear... during impact, these gears can slide and become not fully engaged. That is the strange sound you are hearing. this also prevents the propellers from spinning up fast enough to get fully off the ground. I used a small jewelers screwdriver to reach in and push the problem gear back into place.

Yiboo ch-47 rc helicopter: Rear
If you twist its rotors a little more then the lift can increase. But try to twist then only if they could be else you may become minus them and I would hate it.

Yale diesel fork lift forward tilt not working back tilt fine
Other hydraulic functions work so it won't be a lack of pressure - likely to be a control issue though not necessarily a lack of supply through the valve.
If the tilt ram is a single double-action type of ram one side must be exhausted in order to move when pressure is applied to the other end.
If the oil can't be exhausted from the lazy end it won't matter how much pressure is applied to the other end.
