My transmitter is a spektrum Dx7 can is this model upgraded ? where should the serial number be I cant see it on mine but then I did buy it second hand and it will probably be registered to some one else

If its the old original Dx7 then no it cannot be upgraded, but there is a newer version of the Dx7 about the Dx7s it looks like a Dx8 and Is also up gradable, generally if it has an SD card then it can be upgraded  with the latest Airware (the spektrum tx firmware)

[MadMax]

yea mine is the original dx7 so no upgrades to be honest Im very happy with my dx7 and have no plans to change it any time soon

There is a new Dx8 firmware update out from the Spektrum community web site linked above, Note though backup all your settings / models before use, and check every thing before flying there have been a coulple of reports of trims / sub trims being changed and dual rates, there are no official problems reported

Spektrum™ DX8 AirWare™
Change Log
Version 2.05
13 August 2012
Software Features
• Added support for GPS and High Current telemetry sensors.
• Enabled up to 32-pole motors for the brushless RPM sensor.
• Enabled SD telemetry log file
• Enabled ability to configure inactivity timer
• Enabled backlight configurability (Auto/On/Off)
• Enabled dimming control of the orange Spektrum LED for night flying
• Adjusted vibe motor RPM to be less aggressive
Software Corrections
• Fixed bug that could reset the radio when scrolling through Mix options.
• Corrected L/R trimmer 'forgetting' assignment after power cycle.
• Improved translations in French and Italian screens.
• Corrected export of flap configuration.
• Corrected over-travel of flaps that could result in reversed operation at extreme
deployments.
• Corrected switch change on Acro throttle cut screen when going from the initial
switch selection to the edit page.
• Corrected timer to work properly in Throttle Out mode when using reversed
throttle channel.
• Corrected end-point adjustability when Trainer is used as an input to a channel.
• Corrected trainer normal Master mode so that it doesn't modify controls from the
slave. In previous versions it could reverse channels vs. what was expected.
NOTE: This change affects sub-trim and travel of existing models and ones you
will import. You may need to adjust sub-trims and travel on all control surfaces in
both airplanes and helicopters.

There seems to be quite a few reports about peoples models being messed up with this upgrade, have you tried it gaza has it messed any of your settings up ?
From what ive read they have altered the way the sub trims are used / seen and it affects swash plate settings or summat like that 

[Gaza07]

Well I upgraded mine last night and I hope I havent made a mistake  I will check things out later 
I only have 2 heli's setup and because they are flybarless there is not trim or sub trim used, so hopefully it will all be ok, I dont mind adjusting a few things, and the upgrade brings the dx8 settings inline with the dx10 and dx18 so in the future things should be simple

I bought my dx8 secondhand and has been registered by previous owner, anyone know how i would go about upgrades?

[Gaza07]

Could you contact the previous owner and get the login details off them and then login and change the details in the account, or you might try emailing spektrum and asking for the account to be altered or wiped but they may refuse with out some proof of ownership
