My experience with guys at clubs and in the hobby is generally that they are always very helpful and generous with their time. You may have just hit a bda club, or hit it when they were having a busy or bad day. Don't let that one experience put you off. These guys love this hobby, love to talk about it and love to see newbies getting hooked. too. Good luck with your 400.

Repeat after me:

"swash plate"

not

"squash plate".

-----

You changed the SERVOs, not the Gyros.

-----

COLLECTIVE, not "collecter"

-----

I recently helped a fellow with a Blade 450. The SWASH plate moves DOWN to give you POSITIVE pitch.

Cyclic pitch will make the SWASH plate tilt forward, to the rear, to the right, and to the left. Cyclic pitch will also affect the flybar paddled in the same manner as it does the main rotor blades. The amount of pitch, and whether it is positive or negative at any given time is dependent upon WHERE around the path of the rotors, the rotor blade or paddles happen to be.

COLLECTIVE pitch raises and lowers the pitch of both blades in the same direction, by the same amount, at the same time. Collective pitch remains constant, no matter where the rotor blade happens to be around its path. Collective pitch will NOT affect the pitch of the flybar paddles.

De'ja vu all over again...

Sept 30, 2012:

I posted this link to the solve the same problem you're having today:

https://rc.runryder.com/p4325158/

Please take the time to read it, to follow it, and perhaps even to understand it.

-----

Your swash plate will have to move DOWN for you to get positive pitch.

When you move the LEFT stick toward the top of the transmitter (increasing COLLECTIVE), the swash plate MUST move DOWN.

When you move the LEFT stick toward the bottom of the transmitter (decreasing COLLECTIVE), the swash plate MUST move UP.

If this goes backwards, go to your SWASH MIX menu of the transmitter and change the sign of the PITCH number. If it is currently -60, make it +60. If it is currently +60, make it -60.

Simple, easy to do. Just do it.

Thanks for all the help, and ha ha ha PUSH.

Check that the rudder stick moves the tail blades in the right direction. Then check that when you move the nose of the heli that the tail blades move in the correct direction to compensate for the nose movement. The compensation direction can be changed by a switch on the gyro. For the 401 to work right it must also be in AVCS mode when the power is turned on.

For the tail:

RIGHT RUDDER control on your transmitter MUST make the tail rotor servo PULL the tail rotor pushrod FORWARD, toward the NOSE of the helicopter.

If the servo pushes the rod towards the rear when you apply RIGHT rudder, you MUST go to your TRANSMITTER CHANNEL REVERSE menu and REVERSE the sense of the RUDDER channel. Do NOT proceed until you accomplish this simple task.

Next, with your gyro initialized in HEADING HOLD MODE, pick up the helicopter, and turn the NOSE to the LEFT while watching the movement of the tail rotor servo and pushrod. When you turn the NOSE of the helicopter to the LEFT, the servo MUST PULL the tail rotor pushrod FORWARD, toward the NOSE of the helicopter.

If the servo pushes the rod towards the rear of the helicopter, then you MUST go to the GYRO "NOR/REV" switch and set it to the opposite position.

BOTH the TRANSMITTER control AND the GYRO control must be set to control the servo properly. Either one of them being set incorrectly will cause your heli to spin uncontrollably at lift off.

-----

While we're talking GY401 setup, the GY 401 MUST be powered up and allowed to complete its initialization sequence while operating in HEADING HOLD mode. At the end of the approximate 3-second power up sequence, the red LED on the GY401 must be ON. Not flashing, not off, but ON. If is it NOT on, you did not initialize in Heading Hold mode.

If you're flying a Spektrum radio, MAKE CERTAIN that when you bind the receiver to the transmitter, that your gyro gain control setting is set to select Heading Hold mode. This will guarantee that during the period of time where the transmitter and receiver are completing their power on handshake sequence, that the GY401 is receiving the correct setting on its Gain Control lead.

Also make sure during that same binding process that your throttle setting is at LOW, as this will establish the fail-safe setting for the throttle channel.

-----

When you change out servos, one brand to another, you need to beware that not all servos from all manufacturers turn the same direction for the same stick movement. For instance, if right stick makes a Futaba servo turn Clockwise, a JR servo will turn CounterClockwise.

When you swapped out Hitec servos for the stock Eflite servos in your Blade, you did not realize that you also installed servos that move in the opposite direction from what the original setup expected. This also explains why your tail rotor and gyro both are currently set to run in the wrong direction.

The TRANSMITTER needs to be correct.

The GYRO needs to be correct.

You can't have one without the other. All or nothing.

Take time to read and understand the posts. You will learn. This is not rocket science.

Everything you actually NEED to get your Blade 400 flying properly and under control is written and explained in great detail in the two posts whose links I have provided.

-----

Also -- set your helicopter on a table in front of you. Nose to the right, tail to your left.

The tail rotor turns COUNTERCLOCKWISE. If it goes the other way, your tail drive belt is twisted (1/4 turn only) the wrong way. You'll need to fix that, making sure it only has 1/4 turn in it.

Tail rotor blade on the RIGHT side of the tail rotor shaft travels UP. Its control ball is on top, as is the tail rotor blade leading edge.

Tail rotor blade on the left side of the tail rotor shaft travels DOWN. Its control ball and leading edge are on the bottom.

-----

Make certain the pulleys at both ends of the belt are securely attached to their shafts. If either one is slipping, you'll need to fix that.

Blade400-try it again
Tail going in circles.Well i looked in the Blade400 boodlet and the Squash plate is moving the correct ways.But NO LIFT ,I also looked at the 401 setings,but i never moved them and i know that it did lift off the ground with the settings on the 401.is it in the TX.
I know its got to be something simple. ha ha ha

It's not the transmitter.

It's not the gyro.

It appears to be that you simply fail to read, understand, and follow the help you have been given time and again.

Game over.

Sorry DO read, and was on the web AGAIN and look for testing a 401 gyro out, and found a person that just Moved the gyro with his fingers while it was on the heli, and you could see the rudder moving,that showed the gyro working. I just did the SAME turned every thing on and grabed the gyro and moved it left to right and NOTHING MOVED. sooooo I think their is some thing wrong with the 401. when i bought it off the internet some one told me that it was a fake and it was no good.So maybe he was right.
But thank you dshema for being sooooo ............ friendly. You must belong to the Thomaston DAM club in CT.
Times like this, i feel like telling Any one that needs help to F...off.
But i won't go that low.
John.

Let me apologize if i offended any one here for asking questions about the blade400 and set up. I have FOUND out what was Wrong with it.It was the new 401 gyro that i put on just a little while ago.I took it off and moved it around and the parts inside the case just were making noise,so it was Broke.I put on the old eflite gyro and Just had to reverse it and then i tested it and i got it to LIFT off the floor , with No tail movement.
again thanks for all the help.and sorry to offend anyone.
after my heart attach i just dont have any patience let.
John
