Because I wanted to test with a FET I placed it on the BreadBoard with a normal LED. What I then saw was that it stays lit when the throttle is at idle. Is that as aspected? The LED is now running from the Vbatt switched by the FET. I understand that the figures are incorrect but at idle there is 3m...

Thanks for the tips. I started over; first put the 9X on TAER and then created a new model. Changed nothing in the setup except for changing from 8-channel to 4-channel. The trimming-issue is gone now. However when I throttle down it reaches a point where it stops and when I push the throttle-stick ...

Good news! Well, most of it. The sketch is loaded in the mini and is connected to my 9X. For test-purposes just one IR-LED on a breadboard together with the Arduino. The heli binds, yeahhh. Oops, then goes full-throttle (later I learned it was half throttle). A litttle fiddling with the sticks and I...

Don't fixate on the fs-th9x alone. Although it is the original build, the TX is better known as the "Turnigy 9X". I've been looking for a config-file for the 911 myself and found: http://openrcforums.com/forum/viewtopic.php?f=38&t=1978 but have not tried it yet because I'm waiting for ...

The trim for the rudder is the on the left horizontal as is should be, just like any other mode 2 model. Ok, great. I just misread this sentence: so it's TxER. for trim you just use the trim as you would on any other model. the 'x' channel, which is the horizontal axis of the right stick in mode2, ...

After those 2 changes I'm gonna let it sit till you get yours going and give me some feedback. Have you given any thought to how your are going to update your internally mounted IR module ? You gonna open the case every time ? I expect this will need tweaking for a bit :) Ok, will take a while, wai...

...and when I say TAER there isnt an Aileron. the A is actually called the 'trim' right now because that's how the Irrc's library's demo implementation was setup. so it's TxER. for trim you just use the trim as you would on any other model. the 'x' channel, which is the horizontal axis of the right...

Wow, that is some nice progress! Did some reading on the topic of "channel order" and now I understand what it's for. My v911 uses AETR which is standard for a stock 9X and thats why it works out of the box. For the s107 I will use ERTA, correct? Rudder being on the left stick is just fine...

Had a look at the EEPE-file, which wasn't simple because I have Companion9X installed. It loads without problem but doesn't work so I installed eePe as well. Next hurdle for me is learning about TAER, ERTA, RETA etc. When I look at you mixes, Throttle is on CH03. To have that channel react in the Si...

Cool, you're a Linux-guy! +1 I maintain a server-park with Linux for a living (among other things). Your explanation solved my mistake. Sorry for having to cope with such a newby. I'm reading everything I can at the moment about Arduino and the language. All I'm used to is bash, so it takes a while ...

Hi Randy, /* OffTopic First mod is done: replaced the 78L05 on the switchboard for a 7805. Going from a max. of 100 mA to 1 Amp for the several mods like IR and haptic. */ This weekend had a look at your code and did not understand much of it. Started to read about Arduino and followed some YouTube ...

Whow, now you've done it! As an old-time electronics enthousiast I could not resist finding out what all that Arduino stuf is about and bought the mentioned board complete with an USB-cable with integrated converter. Ohoh, now I'm getting really involved I guess :ugeek: Just kidding of course, I rea...

Out of interest did a little reading and if I understand correctly the mentioned Promini is an atmega328 on a board being a replacement for the DIL-type you are using now. The transistor you talked about must be for driving the LED's. Would a FET not be handier (less resistors and direct connection ...

Haha, your going a little fast for me now :mrgreen: Let me see, the easiest one first: Yes, the layout of the screen is way to large. On my iPad that is a problem. Then from the top down: What do I need the arduino for? Do I need to program the module myself. Uhh, never done that. I was under the op...

Decided against the DSM route for now. Money is a concern because buying a TX-module plus the RX-thingy for the s107 is 'a bit' overkill for a $15,- heli. In the meanwhile my 9X has arrived (yeahhhh, my first real TX) and a v911 is on its way for my first 4-channel experience. New dilemma: I'm going...

To be honest, I'm also considering another route: http://www.deltang.co.uk/irheli.htm
Replace the IR-receiver with a 0.23 gram DSM2 RX.
This also makes it possible to keep using the 9X and solve all the IR-problems like "line of site" and light sources like the sun.

Mode-2 for me too. Europe is a bit of a mix but US is almost always mode-2, so easier to follow discussions. Because I didn't want to have several TX's I was pleased to discover the use of modules in the 9X. The next thing on my list was being able to connect to a simulator. That should be no proble...

That is exactly the board I have. In a topic on RCGroups.com about the Syma S107G it is said that heli's with this board are the original Syma. All others are clones/fakes. I'm convinced that is correct and have two of them. No, I'm not in a hurry :) Even still have to buy a 9X (minor detail...) but...

Nice little project!
I registered here after reading this topic. So yes, I'm interested. I would pay for a programmed chip for the s107g and the extra $5 for the box, well, that depends if you mean a expansion-box for the back of the 9x. Then yes, I would like that too.
