I added fixed slats to my Fun Cub. The goal was to reduce stall speed. I took used about an inch wide wet balsa that I wrapped around the wing to let it dry to form. Then I added little posts to get a proper distance to the wing. The leading gap is about twice as big the aft outlet.
I don't have a degree in aeronautics - just playing with an aging air frame. I did notice a higher angle of attack. Due to the wind conditions however, I could not tell if the stall is now induced later. I will report back in the comments.

As mentioned before I used to watch MTV a lot. Another source of inspiration is the British car show Top Gear. Their camera work exceptional. Watch it for some inspiration - it's on Netflix and Amazon for free.
I have seen a lot of RC videos. There basically are three types:
The third person view: A person other than the pilot is filming the plane. The difficulties are keeping the plane in focus and centered and of course it requires having an camera man/woman often with questionable camera experience.
First person view: The pilot filming the plane in the air through a camera fixed to the head. The pilot's head is following the plane and in theory the plane is always in the picture.
On board view: A camera is mounted on the plane itself and records a flight while in the air. The camera either records on an internal memory of the video signal is transmitted to a ground station for live viewing (or both). Admittedly there are some really cool videos out there using this view.
All of the above are more or less easy ways to document a flight depending on what one tries to achieve. Ideally I would want to use a combination of the above.
While I have not done the first person view yet I do use the other two techniques. I build a snap-on GoPro mount that I can put in between the removable wings on my Fun Cub. It allows for forward and backward facing footage and with some GoPro adapters I can swivel the cam as well to get sideways footage. The rolling...Continue Reading

After posting a couple videos here I got asked a number of times what equipment I use and what tools and techniques I use. I answered every one of them but figured I'd do a quick run down here for everybody to see. Disclaimer: Neither am I a professional, not even an expert nor do I have help in the process of making these videos. I thought everything myself. So by no means expect a cinematic how-to.
I'll chop this into three main steps/posts. The first and most important being the idea, equipment and pre-filming preparations. In later posts I'll cover the filming itself and finally the post processing.
Preparation and Tools
Get the tools together. I use the Hero2 camera for most of my takes. The camera retails currently at 300$. Unless you can get employee pricing or a new model comes out you will not get this much cheaper, even used. Occasionally I recruit a Sony alpha SLT33 DSLR for some takes, however the normal flying field really is not a suitable environment that I like to take high end equipment to. The videos posted earlier are Hero2 only.
Before the Hero2 I experimented with with various keychain cameras (#8 and HK "HD") but they turned out to be unsuited because of the poor video quality especially against the sun and the relatively low frame rate - I'll get to the last point later. I liked, however, the fact that I can velcro these light weight cameras pretty much anywhere on the plane for interesting angles without changing the flight...Continue Reading
