Right servo glitching
Bought a blade CX2 from Hobb-e-mart off of ebay because my LHS was out of stock. With came the documentation of testing and it said "Right servo glitches". The blade flew great the first time but the tail drift was substantial so I boosted the power to the motor to compensate for the left yaw as the manual described (about a 1/4 turn on the screw). Worked great, was able to fully compensate for alll drift with just a little trim, 3rd flight, it makes a sound as if one of the servos is constantly moving or pushing on something and flies erratic. I'm assuming this is the glitching they described.
#1 Why did it happen only on the 3rd flight?
#2 How do I fix this? What parts do I need to replace?
#3 How many servo's do I have? How do I locate the "right servo"?

RE: Right servo glitching
J_Jones84,
Usually, when a servo glitches, it's trying to find it's center/neutral point. It's not uncommon a servo to go bad. Just from a hard landing, it can strip gears in the servo. Can't answer why on the 3rd flight. It's easiest to just replace the whole servo. They are not that expensive. You have 2 servos in the CX2.
To locate the right servo, take off the canopy, and view the heli from the rear, it's be the servo on the right.

RE: Right servo glitching
Thanks.. any websites on how to do it? Disassemble and reassemble? I can actually compensate with left ail trim but the sound is annoying and I fear its probably draining battery life

RE: Right servo glitching
it should be pretty simple and straight forward to replace the servo. You just unhook the ball link and if it is held in by a zip tie, cut that off and slide it out (if it's held in by screws take those out), unhook the electrical connection, and note the position and orientation of the wires, reverse the process and put the new one in. Unplug the motors noting their position and polarity, and then arm the heli and level the swash plate with the swash links that go from the servos to the swash plate.
Honestly it probably isn't draining too much battery life. On my CPP the whole thing draws somewhere around 4A, and the max load if all three servo's are bound is 0.71A, average though is more like 0.10A
hopefully that helps you out =)

Jones84,
Here's a web site: http://www.dacaur.com/heli/bcxhelp/BladeCXAssembly.pdf
You should really learn to use the web more, you can get alot of info. alot quicker. Took me about 30 secounds to find this website.
Oh, you shouldn't really fly it like that when you know you have a problem, repair or replace the defective component. Makes flying alot more enjoyable.
