I kinda like it. It looks easy it is going to ne easy to mod to me. I don't think I'm going to need to buy any new modules and we know the er9x code will be fine. Look at it like this... It a 9x with backlight and AVR mods already done for the same price plus with upgrade gimbals.

There are noticeable board differences.

Yea, the gimbals, if they are better, will be the only "improvement". There doesnt appear to be any improvements made otherwise. Except for maybe the button switches, which appear to be surface mount types on the 9XR, and may be of better quality and have a better feel. It sure looks like a mess in there compared to the 9X.

Any idea what the IC to the right of the CPU is?
I think the one on the left to do the trainer port switching is still there under the ISP wires, but then what would the other one be?

The three terminal device to the left could be a FET to drive the backlight?
I think the old regulators are still there above it, slightly obscured by wires.

Could it be for a digital trim pot or encoder above the stick? Following the traces and wires it looks like it could be going there.

Hopefully someone will post some close up pictures soon.

Its a pot, not an encoder. They wouldnt have had to change/add anything for that.

Not sure what it is. The 3 pin device to the left looks like a new 5V regulator, probably just a 7805. The old regulator section is different. It appears the 3.3v regulator is still the same.

Looking a bit closer, it could be the trainer port IC relocated and the one near the old location on the left obscured by the ISP wires could be the FET for the backlight.

Maybe the extra chip is to support telemetry? Just a guess.

it looks like it could be a 5V AMS1117 voltage regulator or similar. That would be an improvement as it would be an 800mA LDO regulator.

Maybe it's a distress call transmitter to contact Superman in a pinch?

I will have to admit, it is kind of rediculous that we are still guessing on what a product can/can't do and it's already shipping to customers! Complete lack of info is usually unheard of in this stage. Good thing it only costs $50 and we really can't go wrong price wise.

i can't believe they wired the AVR in such a mess and dirty way,
they redesign the PCB and make such an ugly job? now let people do mods to get telemetry... its going to be a real pain for people without a big magnifier and soldering skills.
It would had take almost nothing to map the ISP into a tinny connector for a much smart and clean looking finish. Also would had been much quicker to build has they don't need 500 Chinese losing time soldering carefully wire by wire.

Thats a shame. Didn't expect such thing for a redesigned product.

It's like when they started to sell the 9x with the 2,4 ghz antena build in at top,
the solution was "just wire the module", the most dirty job you can imagine.
Now the solution was "just wire the ISP the DIY way"...

Very nice the PCB message, but should had been: "Hextronik did this botched job"

In my opinion the antena in the handle is veyr bad idea, its horizontal, that means you send bad signal to the model at right and left.
horizontal is early the kind of position used to get nice signal at high altitude

This is true, and simplifies the charging problem. For those interested, there's a nice overview here:

I'm not sure that's true... my understanding is that Li-Ion and Li-Po use the same chemistry, but that the Li-Ion is a liquid (and therefore requires a metal can) while in the LiPos the mixture is gelled (polymerized).

Li-Ion are very dangerous if abused. I think lipo are generally used more in high discharge/charge scenarios and they get cycled more often and used in more extreme ways.

If you want to read some crazy stories about Li-Ion go to candlepowerforums

er9x Mixing Tutorial

Here's my contribution towards the cause... I put together some notes/tutorial on using the mixing menu.

There's a video and some written notes.
