(To see a list of all my Quadcopter blogs, click here).
I’m pretty happy with the overall performance of this quadcopter. I’ve flown it for about 15 minutes a day (the time to expend my 2 battery backs – which I just increased to 4 packs).
I have found it to be reasonably stable. It tends to want to fly forward and I had to put a lot of backwards trim on it to keep it in check. It seems to be well balanced so that is a bit perplexing, but with it trimmed properly it needs only a little feed back.
I do not have great hand-eye coordination, never having had a lot of interest in video games I guess (it was all pinball for me). Further, I really have to think when the QC is flying towards me – I cannot quickly think in reverse. Compared to my experiences flying (one) RC airplane and some RC helicopters, this really is much easier to fly; however I cannot fly it at all in acrobatic mode – I have to have it self-leveling.
The Talon V2 carbon fiber frame has been great and I can highly recommend it. I have hit the gound hard repeatedly. The only damage was to a motor mount and I was able to bend that back out (Hobby King sells those separately and I have ordered a spare).
The KK 2.1 flight controller board has worked quite well too. There has been enough support to allow me, a complete neophyte, to get it installed, setup, and even updated without too much trouble. I would like a fancier flight controller in the future. There’s a good chance that is a future project.
My only reservation with the setup I have is it really doesn’t lend itself to mounting a camera – partially because it is low to the ground and partially because I mounted the battery on the bottom. There are some longer legs at thingiverse.com that can be 3D printed; however, since the battery is on the bottom I don’t think that is going to help much.
I have found a gimbal that I think I can mount and I expect that will be a project in the very near term (I already have most of the parts).
Lastly, I would like to summarize the KK 2.1 Firmware rev 1.6 settings that I am using. Normally this would just go into my project notes, but in case anyone else wonders what settings work reasonably well for a neophyte here they are:
