Not a "flat" version but an "8" version with double or co-axial motors. See diagram below, the new one is on the right.

Now sure exactly why but I decided to build an OCTOP8 rather then an OCTOX8 and then found nothing on the forum about the Plus version. So I have made the slight changes to the code (I know, took all of an hour) and tested the copter in the back garden. http://www.youtube.com/watch?v=LtbseKkHnUI Do ...

Yep, that seems to fix it

Good effort Dominic, especially with wire-ended components

I am not sure if this is intended functionality or has just been missed:- Go into the LCD configuration mode and you will find the default pitch&roll P parameter at 3.3, now change to say 5.0 but change your mind and "exit without save". For the rest of the flight the code appears to b...

MultiWii 2.2 is released and is available here: Many thanks for all of the contributors and for all of those using it and sharing their passion. I hope again this version will animate a lot of flying models around the world. And a big thank you to Alex for his continued organization and management ...

Done, thanks.

Having been testing 3 different camera gimbals, I realized what a PITA it was having to keep recompiling the code every time I wanted to adjust the camera gains in config.h. I was testing the camera in the garden, recompiling, back to the garden etc. It annoyed me enough that I changed the code so I...

Also Hambuger, I have made and tested a code change that moves the pre-compiled camera gimbal gains to the display so they can be changed at the field. I would like in next release to save keep adding it in, how would I go about that?

Almost not worth mentioning but perhaps need to log it somewhere ... build fails when selecting LCD_CONF_AUX but you have no BUZZER, simple fix in LCD.ino John #if defined(BUZZER) &lcd_param_text52, &conf.activate[BOXBEEPERON],&__AUX1, &lcd_param_text52, &conf.activate[BOXBEEPERO...

Once you go into the PID menus system the processor stays there until you exit, so GPS reads will be off-line. If you are messing about in this area try adding the telemetry pages too. For instructions on Tx sticks check out this excellent page ... http://multiwii.googlecode.com/svn/branches/Hamburg...

That set of defines should be okay. My two Crius displays always showed something, the usual fault is a series of random dots on the screen that gets brighter than dimmer a couple of times but will not clear to give the correct display text. Best check your I2C connections again, especially SDA and ...

Is it positive these problems are limited to crius oleds? I have 3 oleds from wide.hk direct or via ebay and never had any of the issues with powerup / init. Yes, I believe it is just the Crius version. I got mine from RCTimer. The HK one looks to have a different set of components with larger capa...

Just to finish off then ... 1) Start by using a scalpel and iron to isolate pin 14 (not 13!) and place some tape to prevent shorting. 2) You must pickup VDD from pin 9 for the resistor, this is the 3.3V supply used by the "core logic operation" (you can probably use the 5V supply but you w...

YAY, FIXED IT Simple schoolboy error before, using the right pin certainly helps! An RC network is all that is required. I have several MultiWii boards but the Crius AIO Pro has constantly refused to work with the OLED display. I just tested it and it worked 20 times without fault I have another boa...

On the photo you can see that you have used the pin 13.

D'Oh, did I really get the wrong pin?!!

These things are too small even with a magnifying lamp.

Thanks very much, let me go try again ...

To add to the story ... The 100 ohm resistor trick didn't work for me. I also tried 470 ohms which made and it worse and 47 ohms. I attached a scope to the 5V supply and it rings, perhaps due to the inductor on the board, and when the display comes on the voltage dips and screws up the display again...

Sorry people, eventually found the solution to the problem ... there appears to be an issue connecting anything to Aux2 (1, 3 and 4 are okay) and because I automatically connected a 9 channel receiver it prevented programming. Having worked that out, I found this thread on RC groups, which I will ta...

Just received a new board from HK today and I can't get it to upload new code. I am using 1.0.1 of the compiler and R1240 code (also tried 2.1). I constantly get standard "avrdude: stk500_getsync(): not in sync: resp=0x00" errors. I have been using a Paris V3 board for a year, probably pro...
