How to get MultiWiiConf 1.7 for the arduino MultiWiiCopter to run on Linux 64-bit (ubuntu)

1. sudo apt-get -y install ia32-sun-java6-bin (you need partner repo enabled to do this)
2. Goto MultiWiiConf1_7/application.linux in a shell
3. Copy and paste this
echo "echo "#!/bin/bash" >>
echo "export JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun" >>
echo "export PATH=$JAVA_HOME/bin:$PATH" >>
echo "bash MultiWiiConf1_7" >>
chmod +x
4. ./

This is the blog post about my Black and Yellow Polaris.

Current setup:
Mystery 2212-6 2200KV motor
6x4 Propeller
Mystery 30A SBEC esc
2x SD50 servos aileron
2x SD90 servos elevator and rudder

I have tested a 2409-12 1600kv motor with a 7x6 apc propeller. Put in a 2212-6 motor instead, because I didn't like the feeling on the 2409-12 motor compared to the 2212-6. I should have tested a 7x4 apc propeller before I changed the motor, but the urge to change motor was bigger than my patience.

This Polaris flies great now after I replaced the elevator piano thread with a bigger one. I had a couple of nose landings because the elevator rod was to weak and flexed. I sanded the nose on this one really nice, but nosed it in the first flight:S

I have a keychain camera on it now, so I can take video from it

My Polaris is now ready for her maiden.

Motor A2212-6
ESC 40A mystery
3x SG90 Servos
3s 2150 25C rhino lipo
Weight 20.65 ounces (AUW).

I'm planning to sand and paint her if the maiden is a success. The weight unpainted is a tad higher than I hoped for, so I'm a tad worried about performance after paint.

I have added bamboo bbq sticks to LE to make it stronger and give it a simple "airfoil" at the same time.

Today my brand new simple delta had her maiden in the moonlight with her lights on. It was kinda hard to trim her because she wanted to dive and it felt more complicated to trim in the dark. After I got her trimmed out she flew beautiful, loops, inverted loops and fast rolls. When the battery started to feel weaker I took her inn for a high alpha or what its called landing. I stopped the motor when she was about 20 cm above ground and let the nose fall into the snow. I got some snow in to the receiver or esc in the front, so I couldn't fly more than that battery. She is now standing in the hall, drying up

My setup
Motor: Turnigy C2230 1780KV
ESC: 10A brushless
Servos: HXT500
prop: EP70x35

I've got 20 leds on my SD for night flying. I can switch them on and off with the TX gear channel. They are driven from the RX by a modified servo circuit.

This is the build thread for my 60" Divinity that I plan to use for filming from the sky.

The Divinity is a KFm4 slow flying wing designed by ApachePilot, plans and lots of info can be found in this thread.

For the main body I'm going to laminate a sheet of 3mm with a 6mm sheet to get a 9mm base to work on. For the KF steps and such I'm using 3mm. The wingtips will be 6mm. I'm not sure what thickness the elevons should be, but I think it will be 9mm laminated there as well. Thanks to ApachePilot (and Dickeroo) for advice regarding what thickness to choose for the different parts.

I haven't decided what motor I should use yet. I've gotten some tips from BatterysIncluded and Jackerbes regarding thrust/watt to weight ratio and possible motors. The 60"'er will get a motor mount that makes it easy to test different motors. Hopefully one of my current motors will have enough power to fly this bird nicely. Motors I'll test on her:
TowerPro BM2410-08T
TowerPro BM2409 -12T
AX 2308N 1100kv

I've cut and glued the 6mm main body this evening. It is bigger than my foam sheets, I needed three parts to get it like I wanted. From 42" to 60" makes a lot bigger difference than I thought!

This is my FireFly built from leadfeathers plans in this thread.

My FireFly has been alive since 21-05-2010. It is a great flier, with a 3s 800mah battery it has great speed and gives me a kick. If i put a 450 2s lipo on it can fly incredible slow in high alpha and I can fool around with the rudder close to the ground. I have flown this plane a lot. When I made my FireFly I made a twin at the same time, so I could move the electronics over when the first one died... Guess what, its not near dying yet!

My setup:
3x hxt-500 servos
2730 - 1500 KV motor
8x4,7 sf prop (cut down from 9")

She has a few scratches now, the prop has taken some bites for instance. I glue the foam back on and every once in a while I paint the spots missing paint. I'm currently making a hatch for her battery. The hatch has a magnet so it will stay put. Its winter here now, so the plan is to tape around the hatch so that snow does not get into the esc and receiver.

Battery: 900mah 2S lipo
Prop: 8x4.3 SF

Because my receivers signal pin on channel 3 is broken, I had to figure out a way to get around it. I managed to use channel 4 as throttle in two steps.

1. PMX 1 - set channel 3 as master and channel 4 as slave
2. D / R - set 0% for channel 4

With theese two settings you get throttle on channel 4 (and 3)
