Yiboo ch-47 rc helicopter: Rear rotor has reduced lift, does backflip when attempting liftoff. Rear rotor turns more slowly when tapping the "collective" on the RC. Took skins off, all 4 shafts turn freely, gears look good (similar on front and back)

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.

I believe the Syma S018 is the same as my Yiboo UJ417.
Mine never got off the ground out after charging for an hour.
It just skitters along the ground. Must be a bad battery. Returning it if I can.
Well my K11 helicopter that I bought from Paddys Markets Sydney Australia last week for $45 gave up after three flights. I suspect the battery is either dead or not charging or a burnt out wire. I suspect your micro RC helicopter has a similar issue. I smashed open my charger with a dumbell weight to see if the wiring inside it was ok. All looks good, but when it is plugged in, it does not even produce heat, which chargers always do to a certain amount. I also dismantled helicopter and took out battery. For $45 it is not worth me buying a voltmeter, another charger (which I cannot find online) and my manufacturer has a dodgy website as well! I recommend keeping your toy for parts and maybe getting another one?
Sorry for late reply, youve probably sorted this by now. This is common problen, some thing to do with the gyro. If you want to spin the rotors without takeing off the trick is to put full right turn then the gyro tries to compensate keeping the rotors turning at speed. To lift of the trick is to get airborn quickly without raising rotor speed slowly then the gyro will keep compensating and keep the rotors running. Had same problem myself, although saved the gears fortunately.
Hope this helps

Mine worked good for 3 days then died..Top blades wont spin.. It worked really well. The guy at (as seen on TV) shop that sold it to me actually seemed to tell me "Do not buy this!" But I bought it anyway at his word that I cannot bring it back no matter what after 24 hours..spent 90 bucks on this junk and there is NO SOLUTION
I found this on xheli.com. Syma S022 big CH-47 chinook.
Looks like the same heli as Yiboo. Lists all spare parts.
Good Luck. Please post results if you order from this site.
I also have the Yiboo CH-47, have not needed parts yet, just got it for xmas from my wife.
