Has anybody worked out how to set up the mode switching to achieve 5 or 6 modes on a Spektrum DX 8?
Any tips would be great! Best regards Nick

I have done it !
This is what I found . The Spectrum radio seems to be very similar to the JR. the PWM values needed are here, the centre ones are what I came up with.
Flight Mode # -- Min. PWM -- Ideal PWM -- Max. PWM#5 -- 1750 -- 1763 -- >1815
#4 -- 1620 -- 1683 -- 1749
#3 -- 1490 -- 1507 -- 1619
#2 -- 1360 -- 1428 -- 1489
#1 -- 1230 -- 1251 -- 1359
#0 -- <1165 -- 1172 -- 1229
The way I acheived this was as follows
Go to servo set up set Aux 1 to 65%-65%
Set gear to 100%- 100% (default)
Go to mixing , select mix 3
select GER >AUX1
Set rate: to 19% and 31% ( these are the rates for gear sw pos '0' and pos '1')
set Sw to gear 1
Leave Offset at 0 %
leave Trim: set to Inh.
Then to check go into mission planner, connect the arducopter .
Go into Terminal
type in 'test'
hit enter
type PWM
hit enter
the numbers will start streaming, Channel 5 is the one to look at .
select each mode and check the PWM is between the upper and lower limits.
You then need to hit enter ,come out of terminal
Go back in to terminal and type set up
hit enter
type modes
hit enter
with both gear and aux 1 away from you this is mode 5 ( down 1) this should be set to stabilise this way in a panic situation it is easy to remember to push both switches away from you to get control of the copter
set the switches to the down 2 position
push the aileron stick to the left to scrol through the modes when you reach the required mode for that sw position select the next sw position and so on.
this is only what I have done I hope it is useful feel free to tell me if there is anything esier to do.
The way I find it easy to remember the six modes is to think of it as down (gear) Aux1 123 and up (gear) aux 1 123
There is a link in the manual here in note 4. http://code.google.com/p/arducopter/wiki/AC2_ModeSwitch.
Hopefully, one of the JR/Spektrum tutorials can help you understand your radio's manual. This is an area where radio manuals are very lacking.
I have always found the best way to learn mixing is to just hook up some servos to a receiver to see what happens, and then just start playing with a new model memory. Without the servos it's all just a jumble of numbers.
If you get it working, consider writing a short blog for Chris to add to the manual. This is probably one of the most asked questions. All the existing tutorials have been written by users afaik.
