QAV 400 and Tarot Gimbal Review

by FPVxplorer | March 25, 2014 | (0) Posted in Reviews

I recently bought the QAV400 ARF kit by GetFPV and had a blast with it. However, I wanted to go further than having just some shaky gopro shots so I decided to buy a tarot gimbal. To mount it upwards I had to make some modifications with a gopro base. The top part of the elongated gopro base seemed to be perfect as the upper part was screwed. With a dremel I made the top flush and mounted the gimbal with the help of some epoxy. Although you can't really point the gopro 90 degrees down, it sits leveled with the rest of the frame and it work as a quick relese gimbal. I also had to move the sensor that tracks the camere because the gimbal doesn't support an upside down sensor.

 

The finished product:


This was one of my first tests without any gain adjustments:

Conclusion: The QAV400 frame with the cc3d is AWESOME and the orange bobbings remove ALL vibrations. I ran with chopped and unbalanced props and there wasn't any jello. The flight times with the gimbal and a 3300mah 4s battery were around 5-7 minutes. However, my gimbal mount has its defects and it came off in some landings. Even though it is an expensive frame, it was worth every penny as a introductory frame. I have never flown a quad before and from a noob perspective is wasn't so hard. The cc3d set up time was round 10 minutes, faster that I ever imagined, although it lacks some features that might be a deal breaker for some, but for the money and quality it is worth getting one just to have the true feel as you would get in a kk2, but more refined. The gimbal was also great and had excelent build quality straight out of the box.

Great footage! I like the idea of the front-mounted gimbal.

Thanks, but it isn't perfect. My next mount will be based on this one:

Seems much stronger and ever stealthier. The bottom mounted gimbals seemed to throw it too much out of balance.

What are your PID settings on your CC3D with the tarot gimbal installed?

I am using Juz's settings, tweaked by Midwestrob (didn't change it because of the gimbal) To counteract the weight of the battery I moved the battery further back. The CG in the QAV 400 should be right in the middle.

Could you share your settings on the tarot gimbal?

Default settings, I didn't change anything except for the limits since the GoPro can't point all the way down, and the setting of the position of the sensor since it is mounted on the bottom of the GoPro. The only thing I didn't like about the software is that you cannot calibrate the sensor, so you need to make sure that it is mounted leveled.

How'd you bring the flight time up to 7-9min? Are the APC less efficient than graupners?
