> Why can't you use your Futaba TX with their receiver? They are both on 72 mhz. Are they using positive shift or is it just the wrong channel?

Positive vs negative shift.


> I don't understand why their receiver design should have any impact on your Futaba receiver.

I'm not sure I understand your question. Their reciever has nothing to do with my reciever, they are just different. With the Futaba RX, the throttle and rudder are adjacent. With the parkzone RX, they are on opposite ends of the RX...the equivalent to channels 2 and 6 on the Futaba I believe.


> I would look elsewhere.

I'm all ears...

> Maybe there is a servo wire crossed somewhere in the fuselage.

I tried two seperate servos OUTSIDE the fusalage, as well as the elevator servo, which is in the same location as the rudder servo, just on the opposite side of the fuselage. so there is no way it's a crossed wire. Neither is it an antenna routing problem, I checked for that too.


> The fact that they have a gap in the channel space on their receive shoud mean nothing to your receiver.

What I am seeing is that for some reason there is cross talk between the rudder and throttle when the servo plugs are adjacent to each other, but not when they are physically seperated.


> More likely it is to accomodate some component inside the plane or to make it easier to assemble at the factory.

It's a moot point. The way they have their reciever positioned within the fuse, there are servo wires going everywhere. I think I would rather have the RX mounted UNDER the fuse in a trap door, rather than on top, behind the battery. The way it is, I have to fight with the ESC servo wires every time I change the battery. Not a big deal, just a observation. I've just been too lazy to bust out the zip ties.


> Sounds like you have an ESC that is defective. Try a different ESC.

This is a possibility...however, why does the original RX work fine?


> Weird!

Agreed!
