According to http://en.wikipedia.org/wiki/Delta_wing my funjet http://www.hobbyking.com/hobbyking/s...less_Motor_ARF is a delta wing and I mix aileron and elevator to fly it. With rvosd I set the radio for a standard plane and the rvosd does the mixing so you can access the menu in flight.

Ah Right ! yeah funjet is delta wing type so fine for you. If only they did a bigger version of the funjet to carry a bigger load, that would be ideal for me.
I'm intending to use a Twinstar or something similar so would just need normal controls.

If you don't need the mixing you wont have to use it, it's just for those who use delta wing mixing in their radios, if they try to access the menu up/down also gives you across and across gives you up/down because of the radio mix. If this mixing was done in the dosd+ it would solve the menu issue.

Would anyone like to try out the new mixing functions?

Daniel

I am keen, bit dark to fly tonight though but will try it out in the morning

Thanks

Mark

I will upload the beta firmware later.

I have a modified GWS receiver that generates a PPM stream. The output from it is a simple transistor buffer with a 4k7 collector resistor. The output is being dragged down from a 5v swing to a 2.3v swing when I connect it to the Dragon OSD+ - is the input impedance really that low? Any suggestions as to what I could do?

regards Peter

Peter,

The impedance isn't the issue. I have a zener on the line clamping it down to 3.3V. That's what's causing the voltage to drop. If you want to avoid that - you can insert a series resistor to reduce the draw-down effect.

Edit: RacerX reminded me that if this was causing a problem for you, a unity-gain non-inverting op-amp buffer (see earlier posts on this) would solve the problem.

I'm trying to calibrate the IMU. I'm using TeraTerm VT but all I'm getting back from the IMU is �b�#H���

which I don't understand! I've messed with fonts and scripts but I'm still getting similar. Any ideas?

thanks

Mike,

Have you verified baud rate, com port and other com settings? Also are you using the FTDI cable or other?

thanks Racer

I'm using
38400 baud as per Daniel's instructions
Com Port 10 - same as used for loading firmware which works OK
using same cable as for loading firmware - USB TTL, same connections

Mike make sure your COM port is also set for 8-bits, 1-stop-bit, No-parity-bit. Also, note that the serial connection to the ArduIMU differs from that used by the OSD board.

Daniel

I have tried few firmware versions to install, and i can't remember which one version didn't work with specified baud rate, o changed it until it started to work. Any way, there are not so many tries

Oh, wait - I might have increased the baud rate to 115200 in the latest one so you may want to change that to 115200 to see if that works. The code shows 38400 but I might have left it in there inadvertently.

Daniel

Hi guys, just flew 6.2beta and I see you have changed to 6.2beta3, what changes did you make? I switched on autopilot a couple of times but I must have had the gain too low or something set wrong because I don't think it had control. The elevon mixing works awesome thankyou. Will link to vid when it's finished uploading
