The traditional heli wiki has a page on how to setup traditional heli. However it is very old and it talks of APM 2.X rather than the current PixHawk. I build a traditional heli and it fly’s pretty good. For other people who might want to build their own here is a short build log. This does not go in too much detail, so if you have any specific questions, I would be happy to answer.
I must say that following the instruction I ordered a 450 size heli. However in hind sight I think getting a 500 size would have been much better. I would have more space to install the electronics. The PIXHAWK with all the accessories need quite a bit of space and 450 seems to be a bit small for it
I used a 1 mm thick carbon plates to make box like structure to install the controllers. 30mm nylon spacer are used to build the box. For vibration damping I am using white foam from hobbyking. This works good for me as the log shows that the vibrations are within 2m/sec-sec ( About .2 g) and I get good performance.
My part list is shown below. As you can see, I used very cheap components and it works great. I was pretty sure that this cheap servo's would not give good performance, but they did.

This is the rough sketch of the parts installed on the plates.

I am running the ESC in governor mode and RSC_MODE in setpoint mode.
Initially I had installed the GPS/Compass on the bottom plate. However in the log I saw huge amount of noise in the MAG1. This was definitely due to main motor because the noise was only when throttle was high. So I moved the GPS/Compass away from motor on the tail and now there is no noise in MAG1. I can even fly waypoint missions and it works great.
Future work. I have a 50 size Nitro heli. Next project is to install PIXHAWK in it. Another blog coming up as soon as I am able to do it.

Hi how are you thanks for that blog I saw that you intended to do that on a .50 nitro heli

This my discussion page I'm doing it on a .30 nitro heli and I need help pleaseee I can leave my phone number also if needed or I can call if to .
Thanks
I also built a flybar less heli using HK45TT kit. However this time I used good quality servos. The controller this time is HK32 PIXHAWK. It works great. This also proves that the PIXHAWK controller from Hobby King works. Earlier I used controller from 3DR.

This is a very good flybar less platform. Unfortunately this is no longer available from US/international ware house. It is available from Russian/Australian warehouse, but they will not ship to US. I was wondering if someone has any ideas how to get hold of this kit from US. I would like it, just in case I crash the one I already have.
