F-86 Sabre 70mm EDF

[Zephyr1]

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.)


Wingspan: 39in
Length: 38in
Motor: 70mm FMS 12 Blade EDF
ESC: 60A
Battery: 2700mah - 3200mah 4S
Endurance: 5-7min

Cool! I love these old first generation fighter jets, and that is a great build!

 

[degriz]

Nice! one day I am going to have to buy an EDF

 

[Willy Nillies]

Awesome!

 

[jfaleo1]

They both turned out great. Can't have one without the other.

 

[shhhhh!]

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!

I vote THIS as the First FT EDF Speed Build Kit!!

 

[Winglet]

Wouldn't exactly be the first. That would be the FT Viggin I believe, but this would be a great addition.

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!

 

[Jeffthehobbyguy]

Great build! I had to modify it to hold a pusher prop motor since I did not have an edf. It flies great and handles good. I love it.

 

[leaded50]

you need use two servos on the elevator, or make a connected servorod?

I actually had an extra servo from an old project that I decided to use cuz I am pretty bad at working with pushrods

Hi Zephyr1!

I was looking Ford an easy easy to build EDF plane. I had a MIG 15 or 17 in my mind. When I stumbled upon your 50mm Sabre, I liked that one even better! But when I found your 70mm project, I even liked that one even more. Recently I’m more into a bit larger and more stable flying aircraft.

I’m having three questions.
1. Did you make the new plans with the round fuselage available yet? If not, can you do so? And can you give info about your cg?
2. In the plans uploaded to your first post, there are two identically parts labeled “B”. I can’t imagine what they are for. They are on the same page where the vertical stab is.
3. Have you ever considered just powering one horizontal stabilizer by a servo And making the other unmovable? Probably the rolling effect is neglectible.

Looking forward to hear from you,

Fredo

Hey @Zephyr1!
I asked some questions about the 50mm edf f-86 you designed but I have moved from that because its too small for what I want to do with it...
Is it possible to put retracts and flaps into the wings? and is it possible to make the elevator controlled fully by one servo? kinda low on servos and I might add a rudder so I dont want to use 5 servos when I could use four.

Thanks!
