When I first built SK!TR I was using HK 10g 2000kv motors and didn’t have much luck. I tried the red KK board and a MWC, both were unflyable. Don’t really like those motors now. Here is my latest quad, a 8″ with Jussi’s shield and a genuine...

Here are some great videos by Warthox that show his stick movements for aerobatic flying.

Tried some flips mid-forward flight. A few crashes but I am getting them down. Best viewed in HD and fullscreen.

Practiced my flips, rolls and loops today. My PID settings allow for real fast flips, which are getting easy to do (and at lower altitudes). It is doing large loops that I think are tricky, have to time it and judge how much nick/roll to give it.

I frequently get asked where to buy some of the frames I fly. Now, you can buy them along with many other things at MulticopterStore.com

Learning to do fast flips and rolls with Jötunn. Thanks to Warthox for the MWC gain settings. Best viewed in HD and fullscreen to see what is going on. Wide gopro makes things look small.

I have swapped out the motors and ESCs on Jötunn to use the Keda 20-50S 1088 Kv motors and 10A ESCs. With this change and using a 1300mAh or less lipo, I have greatly reduced the weight of the quad. This reduction makes it much more agile and reduces the force...

After building and flying my 10″ Kapteinkuk quadcopter, I crashed it trying to do a flip. This caused the RC Timer motors to break and bend. Since then I have switched to Keda 20-34S 1500 Kv motors. I also got a new frame that is made up of components to...
