ArduCopter 2.4 released
Version 2.4 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area. Although not as big a change as the 2.3 release, it still includes a respectable number of enhancements and bug fixes.
Enhancements:
- massive reduction in memory use (>2k saved!) due to Parameters change and APM2 baro lib fix. TradHeli code can again advance in hand with the quad code
- improved throttle range in stabilize mode. You may find that it takes slightly higher throttle than previously during hover but hopefully you'll find that you have more useable range of the throttle stick as well.
- added TUNE_LOW and TUNE_HIGH for CH6 Tuning (I.e. to set tuning range between 2 and 6 set TUNE_LOW to 2000, TUNE_HIGH to 6000)
- new ACRO_P gain for those who like to fly in ACRO (aka Rate) mode
- Loiter improvements including scaling of X speed
- Easier to use motor testing. see the videos for quad and octa-x-coaxial.
Bug fixes:
- remove unnecessary block for next GPS value before saving home loca...
- remove wobble on take-off
- turn off camera pitch control (which uses channel 6) when using cha...
- reduced rate of decent when landing using sonar
- Add support for CH_10 and CH_11 for APM2 users
- fixed Log_Read_Control_Tuning so that it doesn't read too many bytes
The default PIDs are optimized for a 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props, start by turning down Rate Roll P in 25% steps.
Thanks go to the numerous contributors including users and their detailed bug reports, developers and testers. Hopefully all together this will add up to a nice smooth release!

Thanks Don,
Yeah, I imagined I could be like that. So in this particular case, the block between the beginning /* and ending /* is currently in effect, since the beginning /* is commented out?
- Right?

HI Robert
im powered by lipo when not connected to usb - apm powerd by 1 esc and rx powered by apm2 - ....it shows the radio input correctly when only connected to usb only also....
im totally confused cause the rx works 100% when connected to servo or esc?

I have done the power hack and this makes it power the rx as well from the usb power supply so no need then to connect the lipo while using USB . It works really well. here is the link. http://diydrones.com/main/search/search?q=power+hack
Using the lipo and usb together has a few issues so I never do it now.

Could just be a funny leftover parameter from testing if you didn't erase/reset after loading, or as Robert suggests, the Rx is browning out and acting strange when there is current being pulled by the motors.
Note the small change I edited above, that should be rate P. I can reproduce your problem at will by lowering them to 0.

If STAB_R and STAB_P are too low, that may happen too. When I first tunned STAB with ch6 and started from 0, I had no pitch or roll, only when I started increasing the values it begun to respond.

STAB_R?

yes, STAB_R = stabilize roll / STAB_P = stabilize pitch (P values)

thanks for the help guys... I figured I would just load the 3dr default parameters....i know have quad that loiters pretty good...and responds to pitch and roll input for rc..... will need some fine tuning but flies good enough to run thru a couple of 5000mah batteries in no time... some 12" props will be in order shortly as the 11's just dont cut it.....
will update as i go....
