The Discovery
A little while ago I challenged myself to build a small, slow, and most importantly fun and easy to fly aircraft. My main goal was to make a inexpensive plane to get more people into the hobby, and for $35 for everything not including the receiver I think I definitely hit the inexpensive goal. I had built a full scale prototype as a chuck glider and it flew great, then it sat on a shelf forever. A month or so ago I picked it up again and did some more tests then researched and ordered some parts. I built my first prototype (shown in pictures below) and it flew okay, there was a lot of trouble getting it into the air the first time, but eventually it did and it was an uneventful flight. Then I instantly went home and designed a V2. I ripped the electronics out of V1 and put them in V2. The maiden for V2 was crazy windy and I couldn't really tell the flight characteristics. So I took it home and waited for a calm day, and then I figured out that the angle of attack on the wing made it stall really bad. I went home and removed the wing and cut into the top of the fuselage to change the angle of the wing and then I had it. I took it out ton the field and flew it until my fingers froze off! It was finally the way I wanted it! I have updated the plans according to this angle of attack on the wing and I am relatively certain that this design is mostly done. I have now build V2.1 but have not flown it yet, but I am relatively certain that it will fly better than V2, since it is just a more refined version of it.

If you look at the scale it shows the weight RTF.
This one shows a rough static thrust estimate.
Here are some pics of V2.1
This last one has both V2.1, V2, and the original chuck glider prototype!
V2 Maiden Flight
This video is of the maiden of V2 before the stalling problems were fixed in 10mph winds.

Reason for update:
Changed angle of attack on the wing.
Build Video
This one is at a quite fast pace, my internet does not like long videos. Either way here it is!
Please build one and let me know how it was!
I need input for these plans in-order to make better plans in the future so please build one, even as a chuck glider, any input will be greatly appreciated!
Also if you want to support FT you can use these electronics from their store in your build!

It is a little more expensive than my Banggood electronics (coming in at $48 for the FT ones and $35 for the BG) but it helps support FT and what they do. Also it won't take forever to ship and these electronics can be run up to 4s lipos! (although I would not recommend 4s with this model) They are definitely better quality as well. I might just buy these from now on...
Also let me know what you think! Any input you have is very valuable considering I've never built a model like this before, so if you have don't feel afraid to chime in.
