Default -Help- E-flite Blade CP servo plug locaions

Good day everone. Ihave an old Eflite BladeCP that Ishelved a year ago because of a fractured tailboom.Itook all the electronics out of it when Idid that. Recently I ordered and received a new frame, boom, skids and loads of other spare parts.

Iput it all together, and now the helicopter just spins like a top on the floor. Ihave the remote off of the idle up mode which should act like a fixed pitch (correct me if Im wrong). When I increase the throttle the cyclic increases bogging down the motor, it seems like it looses power as the cyclic increases, even though its off of the 'idle up' mode.

To ask my question:Can anyone provide me with a picture or tell me where the plugs for the servos be plugged in? Ive had them unplugged for over a year and totally forgot to mark them. Im usually pretty good about marking wires. The owners manual doesnt show this information, the servo reversing switches are all in the right position according to the manual. Thanks so much for all your help.

The manual does provide information - but not pictures - on the servo plug positions.
<div>
If the controls still do not respond properly after ensuring the servo reversing switch positions are correct, you may also check the servo connections to the receiver of the 4-in-1 unit. These should be positioned as follows (when viewing the helicopter from behind):
Channel 1 &ndash; Right-hand rear &ldquo;aileron&rdquo; servo
Channel 2 &ndash; Forward &ldquo;elevator&rdquo; servo
Channel 6 &ndash; Left-hand rear &ldquo;pitch&rdquo; servo
</div>

Well since my blade CP is less than 5 feet away from me Just in case you're still stuck...

All 3 servos are plugged in with the black wire on the side closest to the tail of the heli.

The top servo spot on the 4-in-1 is the servo on the right side, talking about the two servos that sit side by side.
The second slot down on the 4-in-1 is the servo closest to the front of the heli.
That fills the top two servo slots on the 4-in-1^^^

Then there are three slots below the top 2 on the 4-in-1. The middle spot is the only one used. Plug in the left servo (referring to the 2 servos that sit side by side).

Good luck!

DarkSlate, Koolaidman, Thanks so much. Your help is deeply appreciated.

I verified the servo plug positions they were correct. Still spins like a top.  I guess the receiver/gyro is malfunctioning. When I rev up the motor (off of idle up mode) all the servo's pitch the rotors way up and the main rotors loose speed - all while spinning like a top on the ground (lol). I tried unplugging the battery and adjusting the proportional, but it does the same.

Thanks again for your help.</p>

I'm not 100% sure what you're saying. Is this correct- Neither the tail rotor nor the main rotors are not working properly. The main rotors have way too much pitch, however, they are throwing air in the correct direction. The tail is moving at times, but it's doing close to nothing. It's allowing the heli to spin out of control. Is that what's going on? Just making sure I understand.

Dealing with the pitch on the main blades first-
If the main rotors are pushing the heli into the ground then try the reverse on the transmitter and if that doesn't work, turn the main motors plug around in the 4-in-1. Sounds like that's not the problem though. First, verify that the servos are moving as they should. Turn the Tx (transmitter) and Rx (reciever) on. Wait for the 4-in-1 to initialize. Move the throttle up on the Tx slowly. all 3 servos should move downward at the same time, creating more pitch for the heli. Either hold the heli for this test if you feel comfortable doing so or first unplug the motor and the tail, noting which way they go back into place. If that's all working fine, the heli simply has too much pitch. This is where I have a really hard time explaining but I'll give it a shot. There are two linkages at the top of the rotors head that need to become a shorter length. Pop them off and make them shorter (less pitch). The blades need to be tracked afterward if that fixed the main problem. Tracking the blades involves making equal pitch on each main blade by adjusting the linkages I tried to describe earlier.

How new are you to helis? Just curious. And I hope what I said helps. If it doesn't make sense, let me know what part(s). And if you get the main rotors figured out I'll try to help you with the tail if it's messed up.
