there is no such thing as a RTF except for ka-planes.com and the first time you wreck it you will have to learn how to re-tune it

Status: offline 		This heli is the same as the Walkera 22e. There is a massive thread called "walkera 22e lets talk". I suggest you read through some of it and use the search function.

Good luck

If it flew well before and you hadn't changed anything, it should still have flown well. Did you crash and need to rebuild?

Status: offline 		Usually, there is a bank of dip switches on the transmitter or if you have a computer radio it may be in one of the programming menus. Don't go reversing servos with the motor running. If you reverse the throttle servo the motor will go to full throttle and you won't be too happy. Often, they aren't labeled so you may have to do a process of elimination to figure out which one it is.

Really though, this shouldn't be that hard to figure out. You need to spend some time reading about pitch ranges and some basic heli setup info. Without knowing your swash and heli, I can't tell you which way the swash should move to increase pitch. Basically, as you move the left stick up on your tx (mode 2), the throttle and pitch should both be increasing in normal mode. You need to look at your blades and move that stick to make sure the pitch is going the right way. Swing the head so that the flybar is parallel with the tailboom, hold it in that position (parallel/level) and move the left stick up. If things are working in the right direction, the leading edge of the blades (fat part) should tilt up towards the sky. For negative pitch, they should be tilted with the leading edge towards the ground.

you didn't answer the question from earlier though, did you crash this thing and have to replace parts? Heli's don't tend to change their own setup so I can't see it having been fine before you put it away otherwise it would have come out of the closet in the same condition. Unless, their is some motor problem.

You've got some learning to do either way if you plan on getting that heli in the air and keeping it there.

Status: offline 		i have crashed it once and replaced 50H03-38 Accessories For Upgrade from xheli dont know what they ar called but they hook to the flybar to the swashplate noticed then when i go past half throttle with the motor unpluged i can see the leading edge (fat part of blade) pointing down if that is the problem is there a simple way to fix it i am a beginner with these things and i only flew this thing about 2 feet off the ground and sorta made ot hover a little seemed pretty stable though please help im dying to fly this thing again and learn more thanks alot info on this is GREATLY appreciated

Status: offline 		Well, the truth is that mechanical aptitude is a must for this hobby. If you are to be successful, you must carefully study the construction of your helicopter, and understand the flight principles that make it work. Redvtr pretty much sums the whole thing up. You can also do this: unplug your motor, and then advance the throttle from zero to full. If you observe the blades of your helicopter, the leading edge of the blade will tilt up, and you will have positive pitch. Moving the throttle down should make the leading edge go down. If this isn't what happens, then you need to flip the forward/rev switch for that channel on your transmitter, to reverse the direction of the pitch control servo. Get this right and then plug the motor back in. When we talk about a pitch curve, it is in reference to how the blade pitch is mixed with throttle. Look on your control for settings like starting point of pitch, and pitch moving range. These two things are absolutely critical. A helicopter capable of 3d flight (like yours) can usually pitch its blades 10 deg positive and 10 deg. negative. The starting point of pitch determines what the pitch is at zero throttle. The pitch moving range control determines how much pitch can be achieved in either direction. The beginner should adjust these settings so that at 50-60% throttle, the helicopter can lift itself off the ground. Your starting point of pitch should be perfectly flat, so that there is no up or down thrust at zero throttle. As you get better, you will want to adjust it so that your starting point of pitch is slightly negative, so that you can make powered descents. I don't reccomend this for the newbie because if you get scared and advance your throttle down too fast, you might end up slamming your model into the ground under force. Hope this helps.
