HOWTO Wiki Blade CX Troubleshooting Guide
From Heli-Wiki
Ah finally sorry for messing up a bunch of stuff, my first wiki page...
I am working on step by step troubleshooting for Blade CX and Blade CX2.
Whenever you have problems first try these solutions:
- Readjust your proportional - on 4in1 inside your canopy, in the CX there is 1 pot on the CX2 there is a gyro gain and a proportional pot I believe.
- In aluminum parts - Lower head is 2 pieces not 1, make sure both pieces are tightly screwed in and the top piece is screwed into the predrilled holes on the outside shaft
- Make sure swash is level when you turn on RX and Tx. Also look at the actual servo links, verify the top of the 2 links are also level, this is almost more important than the swash being level.
- I noticed that the plastic from the tail sometime limits the movement of my right servo, make sure it's not binding. A tail boom will also fix this issue.
- Make sure the pitch connector on the top is not too tight or loose. One blade will pitch up and the other will pitch down causing some funky spin.
- Make sure flybar is straight/level ^ will cause same thing, sometime toiletbowl'ing.
- Check speed of both motors see if you can see one spinning faster/slower, they should begin spinning @ approximately the same time.
- Check the movement of the top head, if it lifts at all when you hold the flybar you might tighten this usually this goes along with checking the lower gear is correctly screwed in. This mean the screws are tightened onto the "flat" portion of the inner shaft near the bottom.

HELICOPTER HAS FORWARD OR BACKWARD TENDANCY: (gg)
- Check center of gravity; hold end of flybar (positioned perpendicular to fuselage)by the tips, and lift heli off of surface. Then look at the skids in relation to the surface. Does it lean forward or backward? Check Battery to make sure it hasn't slid aft in the holder. Use velcro. This is especially important after a hard landing or crash.
- If You have to use full trim to eliminate or reduce forward or backward flight tendancies, and have performed the above, then adjust the swashplate ball to servo horn linkage on the Left or Port side of the swash plate. Adjust by 180 degree imcrements. This requires that only the front canopy be removed. Pop the linkage off of the swashplate ball joint and shorten, to lean swashplate more aft, if the heli has forward tendancies; and lenghten to lean swashplate forward if heli trys to back up on You. MAKE SURE BATTERY IS DISCONNECTED, so as not to damage or off center the servo. (gg)
- Check blade balance by putting over a ruler if you dont have balancers, see which side is heavier, add weight or trim up other side.
- Heat issues - I hate to say it but there are definitely some factory issues with heat, check out any of several forums for fixes, many people drill small holes in the canopy which both, lets heat out and also allows you access to the pots on the Rx.
- Watch flying in small areas or outdoors, the blade has a tendency to catch any wind, including it's own even just a little bit.
- Battery could be low (very dangerous for battery, make sure you don't fully discharge Lipos, I had 1 go dead by just leaving it on overnight in the heli. dead. No worky, $30.
- Most people have problems with nose going right. Try starting your bird with rudder trim (left, under stick) to hard right when you turn on the motor, then it may initialize this as "center" giving you more nose left trim options. I'd say first check the pot then this.Bold text
