Divinity, 42" KFm4 Slowfying wing.

Welcome to the world of "Diviinty" , my attempt in designing a larger slow flying all around wing. As the title says, Divinity is built using a KFm4 airfoil, has a 42" span and comes in between 6-10 ounces RTF. Below you will find various pictures to assist you in building your own. I would like to thank those persons who came together in helping me bring Divinity to you, my fellow modelers.

Lastly, there will be a "Proof of flight " video that I post showing all my designs/creations.

I hope to see others building this wing; it can easily be flown at indoor venues/arenas. I have since swapped out props and have gotten 35 minute flights with throttle maintenance. This wing will easily fly at 1/4 throttle.


***Specs***

Foamboard 20"x30"x 5mm
Motor: E-Flite Park 180
ESC: Castle Creations 10A
Rx. Berg 4L Micro Stamp
Battery: E-Flite 2S 7.4v 430mAh
Servos: JR-S185
Prop:GWSEP6030 or 6x3 direct drive

Enjoy!

***EDIT***
(Post 146 of this thread shows the end result of flying Divinity in winds above 15 MPH. The result is that of performing rolls in higher winds. Also a higher AUW with a higher and heavier performance motor was used.) Because of this, I would reccomend that you install a spar directly across the cOg if you plan to use heavier electronics and wish to fly in winds above 15 MPH. For a real windy weather ship, try coroplast as a building material...to really give you some zip

ApachePilot,
I hope you will put all of the information on Divinity, your build photos, etc on here. I have put up one of the photos that you had in the KF thread so that I can ask you how you ran your wire from the servo to the control horn. I am sure it is in a tube, but I guess I was just curious if it is just piano wire or some other material. Do you have trouble with resistance or binding in the wire? Is there a trick to keep it moving smoothly?

They are micro flex rods by Dubro. There is really no resistance, but I use Talcum powder or baby powder for smooth action.

Hope this helps.....

Cool wing...I have a small motor, ESC, and batteries on order and depron and FFF out in the garage. I have printed out the plans and need to cut templates.

In your construction notes it says to put strips on both top and bottom of the wing. On the full sized drawing of the strip itself it shows to only require two. Which is correct? If only on one side, I might just use the fold in FFF to get a nice rounded shape on the LE.

Both the top and the bottom of the wing will have a KF step. The triangular pieces seen in the plans/pictures at the wings center are only placed on the top side of the wing, where small pockets are made to hold the electronics with hot glue and/or velcro.

I hope that clears it up....
