WARNING BELOW: I made a mistake!

The instructions really ought to include this as I would not know.
Unfortunately mixing is dependant upon your radio so the instructions on most ARF's leave this to you.

For Futaba, exponential is negative where other Tx units may be positive. So you are saying 35% Expo on low rate and upward of 50% on high rate or are you talking about the percentage of throw to set up on full and low rate.
Since you are using a Futaba I'm talking about -35% expo on low rates and -50% expo on high rates.
This is different than "throw" or surface deflection, which I gave you separately above... e.g. the 8mm, etc.

7-8mm and 10 - 12mm on high and low rate is easy enough by setting the dual rate high or low to get the right throw. I have not used 50% Expo though.
You want the control surface to deflect UP AND DOWN by 7-8 mm when your TX is set to low rates and 10-12mm when the TX is set to high rates.
Likewise you want 35% expo on low rates and 50% expo on high rates respectively.
Remember Expo is a mechanism to compensate for the fact that you have a server that provides circular motion, while driving a linear rod.
That means ( remember your Geometry? ) that the rod moves SLOWER or to put it another way, your control surfaces move SLOWER as your TX stick approaches the extremes of movement, while the rod moves faster when the stick is close to center.
In effect slight stick movements around center cause much bigger deflection changes of the control surface.
Expo compensates for this. 50% produces a LINEAR correspondence of your control surface to your stick giving you nice smooth control.
However "Throws" ( or control surface deflection, AKA "end point adjustment" ) is not the same as Expo.
Normally the more deflection you have, the more you want the movement around center equalized.

As long as we are getting into the nitty gritty, I have a Hitec Supreme 8 channel Rx and Futaba 6exa Tx as mentioned. I can use channel 6 for left wing (flaps) and run the right wing to channel 1 (standard Airleron). Note the two wings are routed to a single plug so i will have to remove the Y connector and then connect these separately as noted?
Elevators are also run in parallel through a Y conenctor and I assume got to channel 2 (elevator)
I'm sorry I have several of the NP planes and I was getting yours confused for a moment with the Mig-29.
No on yours you can leave the ailerons on the single channel. I forgot that your has separate elevator servos and that one is already reversed.
You can leave the wings on channel 1 and the elevator on channel 2 as is standard.
WARNING: - I had the Delta winged Mig-29 configuration in mind when I first spoke about elevon mixing, you - DO NOT - need Elevon mixing with this plane, nor would it work. WARNING! Danger Will Robinson! Danger!
The throws and expo info is still all applicable.

I will of course refer to the Futaba instructions but again want to be sure with an expert on this before doign anythign. I did by the way run the battery and motors to cycle them. I assume 2 -3 times shoudl adequatley condition this battery.
Yup, good move!

I did note that there is a 2200 Mah hour battery and wondered about upgrades to this mainly along the lines of the 2200 20C batteries that are on sale on NitroPlanes. I know I will want a spare battery but the higher C rate I assuem out to give this thing more push and perhaps better flight time. Any advice for upgrading that won't have me bruning out parts.
Thanks in advance

Please PM me on the latter.
