Today my new #naze32 - #Rcexplorer frame arrived. I had problems to run the controller under linux. Cleanflight always showed "Failed to open serial port".

Here is my solution
1. Check dmesg for "cp210x converter now attached to ttyUSB0"
2. if not available you have to install the driver, it's included in kernel 3.13.x and above
3. Check the permission, echo > /dev/ttyUSB0
If it fails, change permissions
sudo adduser <MyUser> dialout
sudo chmod a+rw /dev/ttyUSB0

Done!

Tricopter repaired!
I've successfully repaired my tricopter yesterday. I had to change two motor axles after my hard touchdown. Meanwhile i've ordered Davids super-duper brandnew, super simple #yaw mechanism. It's really neat!

To enter next level, i've ordered #fpv equipment today.

Yesterday it happend, i smashed my #tricopter down to earth. I was flying about 15meters high and then i lost control. The result: one motor axle is out of shape, two propellers are broken, the yaw mechanism is totally damaged.

I was happy to see there are spare parts available for the motor. So i ordered a new axle from china. I hope it will arrive soon.

Maybe its time for a new version of the #yaw mechanism? I think a yaw with zipties is more resistant - as David already said ;)

2nd tricopter build!

Today i've done my 2nd #tricopter build. It's based on Davids 2.6HV design, http://rcexplorer.se/projects/2012/07/the-tricopter-v2-6hv/. Last year i did the first, but after the yaw mechanism broke apart i've finished this hobby for a while ;)

After spending some time for redesign, it's done:
- A brand new yaw mechanism
- Simplified vibration damper system

Parts list
- Front booms are made of beech, 13mm², 35cm
- Rear boom is 13mm², 38cm
- SunnySky 2216 880KV
- HobbyKing 20A Ubec, SimonK
- KK2.0, FW 1.6
- 10x4,7" Props
- Spektrum Dx6i
- Savöx SH-0255MG
- XT60 connectors
- 2200mAh 3S

The yaw mechanism is based on David's original design - without the direct connection to the servo. I had some trouble with it, after 20 liftoffs the gear broke. I decided to build another yaw - with indirect control.

Back in the sky - and down to earth :(
I had some connectivity problems with the yaw-motor, above 20m high the yaw lost the signal. This was again a hard touchdown.

Back to hangar ...
