Versa Wing converted to Funfighter

[Kristoffer]

As a result of my first Versa Wing diving straight into the ground during maiden flight, the whole center of the wing exploded.
Leaving only the wingtips and most of the Elevons intact.
So I tried to salvage as much as possible of both wings, with an idea to make a mini wing later.



The reason it "exploded" is because of the foam sheets not having the paperfilm found on the standard Dollar Tree boards.
Anyway, I buildt a new Versa Wing, and started wondering what I could do with the leftover wings.
And after a mistake in ordering some motors from HK, I got some 28-size motors and among those a Funfighter 1950Kv.
So I started Looking at some Funjet/Funfighters for inspiration.

Used som leftover pieces of foamboard, and started fabricating a centersection consisting of a "foldover" wingshape and two sides.


A little sanding to smooth out the straight edges.


A little hitch when I got the motormount, in the typical Hobbyking fashion.
One mount, four screws, one motor. Not quite..
Two of the motormount holes are offset, and two different dimensions on the holes in the motor, but Yes the screws only fit two of the holes.

Had another mount lying around so I just had to use that instead.

So here is the rough result before finishing, and paint/decals.

Cant wait to try it. But of course today the first autum wind really hit, even knocking over some small trees in the neighbourhood. So I'll get back with some video

Had some leftover spraycans from another build and gave it a quick coating, just for orientation.
It's a prototype, and since I have no idea how it will fly, I didn't bother too much on the finish.
And also because of the lacking paper on the foamboard, I cover the whole thing in packaging tape.

Looks sweet. Try rotating that motor mount to see if it fits the other way? All of my mounts like this only fit if there in the proper orientation, because those holes are not in the shape of a perfect square.

A 5.25x6.25 APC prop on 4s will turn that thing into a beast ive got it on my 67% spitfire 100mph+

Looks good! That motormount is pretty normal, a lot of motors have that bolt pattern (2 bolts with 19mm spacing and 2 with 16mm iirc). It's a pusher as well, should be fine with just 2 screws if you have no other options.

That looks awesome! Can't wait to see it fly, it should go smoking fast.

Thanks, I've had a few HK motors now, and I'm used to some modifications or mismatches.
The motor really did have two different sizes of holes, but the screws were all 3mm.
And the motor mount must have been for something else.
I had a standard 28 size crossmount that alligned pefectly with the holes.

I will try with a 4s, but I only have 2200's and I am a bit concerned about the weight.
For now I used a 6x4 "APC style" prop.

Maiden..!!

Ohh man!!

I have created the sweetest flying machine!!! :applause:
The wind finally died down right before sunset, and I got to maiden it.
Allright I may be a bit enthusiastic right now, but I have never flown something like this.
I have different planes with different caracteristics, but this was new to me.

I've got about 6-7 flights on the Versa Wing, which in it self is a dream to fly. And so I would have to describe it as a mix between that, and a slopesoarer type plane. When I cut the throttle, it just GLIDES forever..!
But also quite agile with the 1950kv motor.

Flying weight with a 1300mah 3s, is 446grams / 15,7 oz. And that gave me almost 15 minutes in the air (including some gliding)
I have lots of room for a 2200mah, but I am a little concerned about the weight.
With the 6x4 APC style prop it had lots of torque, and climbs vertical with ease!
If I go with the 2200 mah, maybe I need more push?

No light for filming yesterday, but I will try today

Thanks for commenting

You wanna keep it as light as possible that 2200 will be to much i wouldent go much more then 600gram auw. ? Is the versa scaled down or full size

Well, I used the remaining part of the wings after it crashed, so they are each about 15,5"/ 32cm
Total wingspan with centersection: 29" / 74cm

It actually behaves like it could use some more weight to brake through the air, but then again I've only had two flights with it. And I use minimal throws on it for now.
Ailreons 30% and Elevator 45%.

I think maybe a 4s -1300mah would do the trick..

Video..!!

Captured the second flight on a HD Wingcamera from HK.
It is hotglued shut around the circuitboard, so no audio.. Hence the music.

30In wing its not gonna handle that 2200 very well ya you prob would get it flying but. It would come in pretty fast on landing just to keep it from stalling go for the 1300 to 1500mah
