F-86 Sabre 70mm EDF

Earlier last year I designed a 50mm F-86 Sabre that some of you are hopefully aware of (found here: F-86 50mm) and it worked really well! It was incredibly fast and maneuverable. But with the onset of the Master Series Corsair, I realized I needed to up my game. And as I was tired of the 3-4min flight times of the smaller Sabre, I decided to make a much larger one. And the flight characteristics are great and all control surfaces are scale. Oh yeah, and I bought some decals from calliegraphics and they look amazing. (There's a MiG-15 teaser as well. Let me know if you guys want me to post plans for it as well.)

Awesome..yes please post plans for the Mig-15 my favorite jet. So is the 70mm F-86 build the same as the 50mm version?
Thanks,

Thanks! Yeah, I think I'm going to wait on the plans for the MiG-15 when I try a similar MiG-17 this week.

No, the 70mm Sabre is different from the 50mm version. The 50mm is boxier and the nose section specifically doesn't come together as well. Additionally the tail is better on 70mm. Hope that helps!

Hi Zephyr1,

I built your 50mm version of the F-86. Great design! I love flying it. I'm ready to jump into the 70MM. Is there anymore information on the build anywhere? I'm a little confused with the plans. What is the squarish piece with the four rectangle cutouts?? Any construction photos you have would be much appreciated. Thank you!

Hey Mike, I'm so glad you're enjoying the 50mm F-86! I'll try to help as best I can with the plans. Are you referring to this piece?

If so, then this is the back half of the fuselage. So first thing you do will be to tape this to the front of the fuse and then remove the paper from the inside. The 4 rectangles are where the hstab's connect. Additionally this is how i connected the servos! On the right side is the battery shelf and on the left side is the tail.

Ok, so while my transmitter has been MIA, and when I got bored in my airbreath propulsion class, I decided to redo and update the plans for the Sabre. Big improvements this time include: reinforced and single piece htail, a completely molded fuse (this means that underside is formed too), an improved, more symmetrical airfoil (no undercamber), and importantly the use of fuse formers, specifically to hold the EDF and to better join the fore and aft fuse.

I like this better with each new version. Looks great!

FWIW (which is not much) I was looking at the pushrod run you had in the earlier post. I tend to prefer stiffer pushrods so I cross them over from one side to the other if possible. Meaning, for example, rudder control horn is on the left side so servo in the fuselage is on the right. This allows for straighter pushrods and less binding, so less servo stress. As I said this is only worth the time it took to type YMMV.

You're 100% correct, the stiffer pushrods are much better. I actually already incorporated that into the new version!
