Hi, Im new here. Just hoping for some help. Here goes. I bought an s107 for my nephew for christmas. I bought it with an optional a/c wall charger and a set of replacement parts ie. blades, tale fins, tail blade, and what is, I am guessing, the gyro bar. Obviously, I flew it myself at the house first. It flew perfectly right out of the box, so I reboxed it and wrapped it for x-mas. On x-mas morning my nephew opened it and I made sure that he understood how the controller worked and demonstrated (lol) it for him. Once again it worked perfectly at first. He had some trouble feathering the controller to keep in the air without going straight up to the ceiling and the letting off to much and having it hit the carpet before he could recover control. "Not a big deal all you need is practice", I said. Then after a few minor crashes, the blades started banging into each other during take-off. So I tried adjusting the middle knob on the controller, thinking that would be the problem. No such luck. I then checked it out closely and found that the blades were a bit dinged on the edges from hitting one another. So, I replaced the blades (yes I put them on correctly) and the very first take off they slammed into each other and one shattered. So, finnally after mismatching the remaining blades, It still does not work properly. No matter how much I adjust it, it leans hard to the right on take off and as soon as it lifts a couple feet off the ground, bang the blades hit each other and it crashes. Should I just buy him another one or is there a quick, cheap fix????
Depending on the crash,there are a few things to look at-check main shaft is not bent,hitting the ceiling and chipping the rotor blades is a fairly hard crash-The stabilizer bar on top of heli could be damaged or out of balance,loosen and reposition,take a careful look to see all contact buckles are not broken-keep us all posted
Thanks Syma Freak
The main shaft does not seem to be bent. I replaced both sets of rotor blades and the stabilizer bar after it started to malfunction. The contact buckles and screws are intact and the blades are facing in the crorrect direction. Nothing seems broken, loose or bent. I have adjusted the screws on the blades, stabilizer bar etc. from fully tightened to a little less several times. When the blade srews are fully tightened they will not swivel so I know that they have to be a little less than fully tightened. The helicopter lifts off to the right. It doesn't spin on it's axis it just leans to the right and is very eratic the higher it gets, after a couple of feet it tips over enough that the top and bottom rotor blades collide and it falls. The second set of blades collided so hard that one of the top blades broke in half lengthwise. So I reinstalled one from the first set to replace the broken blade. I have adjusted the rotation nob incrementally several dozen times in both directions to no avail. I have inspected all of the gears etc. and nothing seems off. I have made sure that it is fully charged and have not run the battery to complete failure. No ammount of adjustment changes the problem, it continues to take off to the right etc, every time. I am starting to think that it has to be the shaft?
Hi Uncle-lol- yes the main shaft only has to be a bit out to fly badly and of course rotors will hit each other-now you can have a look which way it favors the bend on the shaft by the way the rotors catch each other,many times I have bent the shaft straight by hand-is hollow so just be gentle,slight move fly again to see,then if a bit better bend by hand a bit more,the worst case you either buy another heli use old one for parts,as buying parts and postage can get out of control cost wise-let me know how you go bending by hand--
