Hi I had bought the APM hardware one year back from Fah-Pah , Thailand and succesfully flown the quad. I see a lot of development since then but I was occupied with my personal issues. I am back to my passion now but while trying to upload the latest version i.e. 2.9.1.b it says firmware too big for 1280. Please upgrade your hardware. I can understand the same but is there a way out or do I need to buy the new hardware. I can not shell out more money at this point. Is there a way I can use the tested firmware which can be used on this hardware ? Pls advice. Thanks. SID

Thanks Bill I might just do hang out for the Taranis.  I fly lots of Scale models (plane) and the Aurora is my main radio. I think buying a dedicated radio would be the right thing to do.

@john. Your HiTec will be perfect. If you want to buy a new TX though wait for the Taranis from FrSky. It uses Open9x firmware so is awesome for drone use. And it's only $200!

Glad to be part of the group. On the brink of ordering a loaded quad from however I want to use my Hitec Aurora radio is there anything i should be aware of? Or should I just order a TH9x for it and be done with it.

Re, "where are we with ArduCopter 3.0", we're at release candidate #2 now which you can find here.  There was a temporary problem with the downloads area so initially I could only put rc2 into the old downloads area.  Anyway, the new wiki is the place to get it.

Comment by Charles lakins on May 17, 2013 at 1:49pm

the version 3 is listed there (rc1)

Just wondering when is the Arducopter 3.0 release scheduled?

From the git log I can see that 3.0rc2 milestone has already been reached.

Thanks Randy for saving me a bunch of time - I didn't realize till your reply that I could change parameters from the Advanced Parameter List thinking it was only a listing of explanations.  Dumb me.

     Re where to find the ACRO_P parameter.  You can find it in the Mission planner's Configuration, Advanced Parameter List.

Comment by Jim Frantz on May 16, 2013 at 9:07am

Where do I find Acro_P to make adjustments per the Wiki?  It is documented in the parameter listing and Wiki but I cannot find where to actually adjust it. 

The APM does acrobatics.  WOW!  I'm thinking I need to increase the Acro_P to increase the rate of roll and pitch.
