Default MX400 Swashplate, help please.

Hi there, Im newb to this kind of heli, (I had a CCP).
There is my problem, I cant figure out how to setup my linkages from servos to swashplate IF all the 3 servos (elevation, aileron, pitch) move at the same time... ex: with throttle up, the plate supose to raise at flat level right ? mine wont...
Im using a Futaba 6EXHP radio,
and I feel stupid to ask such a question, but I really need help please.

First, make sure all you links are the correct lengths and the swashplate is perfectly level to the frame, while the radio's trims are centered and sub-trims are zeroed out. Also make sure the servo arms are as close to perfectly horizontal as you can get them.

Are all the servos moving the swash in the correct direction? If they are, the you'll need to reduce the endpoints of the servos that move farthest.

If your servos are moving in different directions, you'll need to go into your swash mix and change the offending throw to a number opposite of what it is now. For instance, if your pitch servo moves the wsrong way when you move the throttle, go into the swash menu under pitch. If the number is, say +50, change it to -50.

This is assuming the servos are moving in the correct direction for cyclic. If that same servos is reversed in cyclic too, simply reverse that servo.

Incidentally, I tried setting up my MX with that Futaba radio / receiver / servo set for several days before I gave up. I switched to a Spektrum DX7 and HiTec HS56 servos and had it dialed in and flying that afternoon. Since then, the radio has been collecting dust.

is this a stock mx400 ??? is it eccpm or mccpm i guess is what im getting at ! if its mccpm to make the servo's move right you should only have to go into the reversing menu on your radio to get them to move right ! if its eccpm or direct to swash you would have to follow jeffk's instruction's
