I am at a loss as to why I have such a interference problem (glitch).
I have the [link=http://www.hobby-lobby.com/yak55.htm]Yak-55 Aerobatic 3D Profile Airplane (Hobby-Lobby)[/link] and once it gets 50 to 100 feet from the controller it goes nuts. The push rods snap on to the control horns and when the glitch starts it pulls the rudder push rod from the horn. All the servos are affected. The plane will roll 90+ degrees in a glitch while in flight.
My equipment is:
Yak plane
Blue Bird receiver
3 Blue Bird servos
Balsa Products 10 amp brushless ESC
Atlas 2312/09 brushless motor
Magnum 3-cell 2000 mah li-po

I took all components from another plane except the motor, no glitch in last plane.

Other facts
I have tried multiple locations for range check
ESC and receiver are 11 inches apart
I have removed the motor (since it is the only thing different)
nothing is touching the carbon fiber rods
I have unplugged each servo (individually and multiple at once)
I have tried a different receiver and transmitter
I have tried a different ESC
I have tried a different battery
I have removed the carbon fiber push rods
Probably some other stuff as well

I don't know what it could be, any ideas?

Its the carbon wing spar. Where is your battery? Try putting everything behind the spar. Are the receivers dual or single conversion?

That all I got.

I updated the layout image to show where the battery is located.

The battery is right on top of the spar.
I am not sure moving everything behind the spar and still maintain balance is possible.
The receiver is a single conversion.

Thanks

What tx? Have you tried a range check with the antenna collapsed? Are you flying any other planes with the same tx and are they having problems as well? I have heard bad things about the BB rx, though it is just hearsay.
I have my battery behind the spar (900 3-cell TP) and it balances and flies fine. My rx and esc are on opposite sides of the fuse.

The drawings do not show the routing of the antenna. Is the receiver antenna fully deployed (not folded, wrapped around a straw or shortened in some other manner)?.

SGecko

It's a Airtronics tx. No. No other planes currently, it had no problems with the plane I was using before. This would be my 4th BB tx, I have had no other problems with them in the past.

The anttena just runs down the side and hangs off the back. It is fully extended.
