Great. I just found this thread and because I own an old MultiWii pro board I will try this. With original 2.4 firmware , there was a problem with drift.
Is this version usable for airplanes?

This is a great tutorial Arduino - ArduinoISP
https://www.arduino.cc/en/Tutorial/ArduinoISP

There is also a forum about this where you will find some answers Arduino Uno R3 as a true ISP programmer for any AVR

You don't need reset pin because it's done through isp (dtr) pin. Maybe you will need to add 10uF capacitor between RST & GND pins,but most important - you should use Arduino as ISP for programmer, NOT USBtinyISP!, but com port must be from multiwii. You flashed uno with right sketch, right? Sen...

Multiwii 2.4 as Slave

Yes, but I want to connect 8 Ultrasonic sensors. There are not enough digital ports. You can connect them through I2C. All on the same port. You just need to assign different address for each one. Also, on second link I posted is explained how to connect Arduino to Arduino. Sent from my SM-N910C us...

Connect it to serial port. RX to TX and TX to RX. Anyway, what data? You can send/receive data through different ports/pins... There are already many projects available in the net

At least you keep to board alive I'm just not leaving any more lengthy replies. Most of the time doing that is wasted. I'm so disappointed with the whole RC forums.

It's a zener diode. Change it. https://www.google.si/url?sa=t&source=w ... 7X_kag7YYg

And it's a W2 not W5. Type W2 diode in google and you will find few replacement

Yep, in the top left corner is a diode. What is written on it? SJ maybe? Also, on the right side of the diode is a little black element with number 5 on it. This is probably the fuse. Check with volt meter how much voltage is on the one side and how much(if any) is on the other side. Same for diode....

You probably destroyed voltage regulator (it should be L350). It's a 5 pin element (between connector and gps chip). Or maybe you smoked shield diode (if it's on this board)
