Hi,
I am having a hard time with setting the pitch on my HBK2. I have a pitch gauge but for some reason I can not get the pitch right. Could someone please tell me the pitch gauge setting I need to achieve....Initially the two rotor blades were off and not in the same plane so I was able to correct that by the connecting rods to where now the blades track in the same plane (pretty much). However, this exercise created another problem. Not the heli has no lift even at full throttle. I know what that is....I probably messed up the pitch settings of the rotor blades and now need help to set that right.
Any pointers/help would be appreciated.
Thanks.

You need to start from scratch...
-disconnect the motor from the esc
-turn on tx
-plug in battery
-flip the idle up switch towards you
-put the throttle stick at the mid position
-check to ensure that the arms on the servo are at 90 deg, if not then remove the arms off the servo and put it back on as close to 90 as possible
-check the pitch of the blades, they should be at 0, if they aren't at 0 then use the links from the servos to the swashplate (lenthen or shorten as needed) to get to 0 pitch. at the same time get the swashplate as level as possible (use swashplate leveler if you have one)
-check pitch of blades at full throttle and 0 throttle, should be +7 deg at full and -7 at 0
-go back to normal mode by flipping idle up switch away from you
-check pitch of blades, should be -1 at 0 throttle and +7 at full
-disconnect the motor from the esc
-turn on tx
-plug in battery
-flip the idle up switch towards you
-put the throttle stick at the mid position
-check to ensure that the arms on the servo are at 90 deg, if not then remove the arms off the servo and put it back on as close to 90 as possible

Thanks Druss. I will try it out tonight. However, what is the neutral position (after the gyro is synchronized and done blinking) of the servo located on the right (if you're looking at the hli from the tail rotor forward). Is it spposed to be at 90 deg (parallel to the floor) like the adjacent servo? It would be best if you or someone could explain what positions the servo arms should be when you connect the battery and the gyro gets done doing its blinking thing.
I also noticed that sometimes the gyro blink really fast (which is normal) and then instead of becoming steady, it starts blinking but not as fast as it initially does. Why does it do that? Does this mean that it was unable to synchronize one of the servos? Cause it seems that the tail rotor servo was not brought to the neutral position. Please clarify.
Thanks.
