Just follow the manual. The Mission Planner will load the correct code for you.

Brad I would wait a week or so and let Malcom, Robert and Randy sort out the I2C freeze problems.

They are very close to a good solid release, 

I added Remzibi OSD integration to code base. It works well  and fits on 1280 for Quads, but requires  2650 for Traditional Heli and Planes.

What APM mega  do you have 1 or 2?

If APM 1, 1280  or 2650 uP

Heli requires a 2650.

Are you using a PC or Mac to load APM software?

version 1.4 2560 pc windows vista .the reason i,m asking is i still need to test my IMU oilpan  to see if it works because i was stupid and hooked up the ground on the voltage measuring pins cant remember what there called at the moment ,so i was looking for code and software thats known too work more than functionality .and thanks for helping

Make sure the heli is well balanced and flys smoothly without APM, then install APM,  I power my setup with a Turnigy UBEC -15A please use at least 8 Amp UBEC, 4 digital servos need power also separate apm power from servo power 

Upload the code from Mission planner currently, ArduCopter V2.1.0r Heli (2650 only)

Please don't connect main motor power or keep pinion off until the setup is done.

Follow manual on wiki, Do physical setup for heli, radio and servos. Use Mission Planner's  Radio Input to cal radio and then use AC Heli setup. Make sure IMU will control swash plate correctly in Stabilize mode.  Then check all modes for any reversed swash motion.  When all this checks out, Connect the motor and Throttle, make sure it turns proper direction and Throttle is not reversed.  

When latest Heli Release is ready you will only need to upload, reset APM,  Cal Radio and test fly.

ok got MP installed and connected now here,s the fun part my heli,s belt cp one front two back servo type

and i see nowhere to switch it . i had a heck of a time last time with the old code does this new code support this ?

never mind i found it

this is moving along nicely so now heres the next problem the collective reversed on the back servos and not working on the front i suspect it zeroing itself out on the front because its working with the pitch

I'm pretty sure you've seen it but this configuration wiki page is definitely your friend while going through the swash set-up.

thanks randy i didn't get that far mission planer quit working so i restarted it reconnected went back in to set up and my setting for the servos was still there but the clock was wrong so i redid the setting to get it right servo,s went crazy and stripped one of them and made it heat up hot so i,m down for awhile ...next update you should put a collective reverse box next to pitch reverse box and i need to get some safe PID,s from you to start out with or maybe i just need to get a HK clone and put this belt cp up on the wall

Brad,

     For the APM1 (which is what 95% of people have), I'd recommend doing Jason's power hack so that the receiver is powered from the usb so you don't need to worry about the servos moving around while you to the radio initialisation.

     Not sure if I totally understand what you mean but there shouldn't be any need for a collective pitch reverse checkbox as you can reverse the direction of each servo as it is.

     In the code (even for the quad) we don't allow you to reverse the read from the radio because we figure it's easy enough for everyone to reverse that in their transmitter.

     If your servos are heating up it might be good to slow down the update rate to the servos (by increasing the servo averaging).  This can be done through the cli's heli menu ('a' or 'd'.  a=analog=125hz, d=digital=250hz) or you can update the SV_AVG parameter through the configuration screen. 0 or 1 = 250hz, 2 = 125hz, 3 = 83hz, 4 = 62hz, 5 = 50hz.

    Sorry this bit isn't documented anywhere.

Sorry to hear about your servos,

You may want to try Blue Arrow digital servos from HK they have survived many cycles of abuse from APM software loading. I have standard size D50011MG on cyclic and D50012MG for rudder, also have mid size D26013MG as Pan Tilt for camera.

HK-600 would a good upgrade for you. It will fly smoother as its mass helps with stability.

I usually turn of UBEC to Servos when I load new software to stop wild swings, but when I forget these servos have taken a few second abuse before I turn off their power. Usually only Channel One swings wild.
