Your video looks great. Your gimbal works fine. I think you need a bit more tuning specially on roll. I will try my opcc with the Cossacks firmware. Could you share your configuration file?
What is the total weight of it?
You have to do something for the strings.... :-)

Tigar,

AUW is 5.1 Kg including gimbal, camera, and 2 X 4S-5000mA batteries. Don't know how to upload the .uav configuration file. I'll play around with it. If you know an easy way, let me know

Just thought I'd throw up a pic of my latest

Description:

This is the almost completed mechanical portion of my new retractable landing gear. Now I need to learn how to program in C+ so I can operate them with Arduino.

Once I figure all this out and have it installed, I can start on the last design element of this build. Modify the gimbal to three axis and install a video Tx and additional RC radio so a 2nd person can take video while someone flies this monstrosity

Today I completed the mechanical portion of my diy electric retracts. Now I turn my attention to creating an Arduino program that will operate them from my Tx. There are a few examples out there and I hope to incorporate their code. Once I have them working and installed, I will finish the pan axis for my gimbal. No use having it now as I will see the legs in my video.

Here are the pictures of the retracts

I am considering starting a new thread for the retracts as there may be someone out there that has more experience in Arduino than me (Zero experience) and can help me with the programming. Maybe in the Multirotor Talk or electronics section?

I love you work. Mind telling me what motors you use for retracts?

Working on the code for my retracts. I have come up with a simple code that reads the switch on the Tx and turns the retract motors on for a fixed time. They simply stall after they reach the endpoint of travel until they time out. Thank you echo9alpha for your offer of assistance. I have pm'ed you.

@rcsnow... These are the motors I am using

Finally got my retracts mounted (after a little redesign) Shot a quick test video of them working...

Now I am going to design and build the pan axis for the gimbal and then I plan to convert the gimbal to brushless. Already bought the motors. Now just need to find the time to rewind them.

What about the controller for the brushless? Are you getting a commercial one or you are making your own?

Tigar,
Planned to buy one of the Alexmos controllers once they are a little more available. However, someone on the OP forum achieved a similar result with a CC and a modified ESC!!! I'll rewind my motors and sit back and see what happens.

I think you will have to replace your ring magnet with individual ones to get enough torque. Let me know how it turns out.
