Introducing the Javelin, simple yet sporty

I recently set out to build a plane based off of the C pack to use a wide variety of batteries and still accept a 2200mAh 3s. Simple but fun designs are some of the best. I was shooting for a jack of all trades flight envelope and I think I nailed it. The large surface area of the wing makes it super stable and floaty when it has to be. It can be throttled back to 30%-ish throttle and cruise for 12 minutes even in our dreaded Wisconsin cold robbing battery life. If you pin the throttle it is pretty quick as well due to its low profile slipping right through the air. With the large control surfaces I made for mine it also is a fairly capable 3d plane but I have yet to push it because I only just maidened it. My only gripes so far is difficulty keeping orientation when flying in overcast weather since it blends in with the clouds and how far this thing glides in ground effect! I swear it just floated a foot above the ground for probably 50 yards. Let me know if anyone is interested I might end up making plans.

Edit: Special thanks to @Grifflyer for making the plans I made better and converting them to digital. Here they are. https://drive.google.com/open?id=16lem7R06Ttek6lGuCAdhaUiJEgVxHIxd When someone decides to build it let us know how much it weighs because I ended up crashing my original from a brown out before I got those specs.

That looks pretty cool man, like a low wing ugly stick kinda thing. @The Hangar likes those planes! He might build one and try it. I built a low wing Scout as well back in the day...

I like what you did with the elevator and having the servo go directly into the fuse, it cleans things up a bit.

@PoorManRC likes those Planes TOO!! 😉 I also prefer fatter Fuses, but I really like your design!! 👍👍
It does look like a wide Envelope Aircraft, and something that a mediocre RC Pilot like me can enjoy.
If I can get the necessary assistance, I'd LOVE to try it.
Sweet Plane!!

Thanks man I plan on doing a build video with my plans to help anyone through any discrepancies my plans may create.

Sweet Plane!!

Your plane looks great!! Have you gotten any flight footage yet?

I’m working on plans right now. Unfortunately they will have to be hand drawn. I don’t want to purchase illustrator just yet and inkscape just isn’t intuitive for me. Hopefully they still turn out alright.
If you make the hand drawn plans I can trace them out for you and make them look all fancy if you'd like.

Ill try to get flight footage tomorrow. And I’d really appreciate it. I am not as precise as I’d like to be dimensioning this by hand. All the measurements are pretty simple though. Only complicated thing is the wing is rolled instead of folded which takes a bit more patience and time.
