F-86 Sabre - 50mm EDF

[CrshNBrn]

But I only have a 50mm edf and I’m not really a novice pilot but I have never flown any edfs

Then go for it. Its just foamboard, after all. If you do, I'd recommend burying the servos in the wing (maybe with a servo arm protector) or even putting them on the top of the wing so that they don't scrape on landing.

Ok I’ll do that. I downloaded the plans and I don’t see the *thrust tube* there do I have to make it myself?

 

[CrshNBrn]

I did. I just wrapped it around the outside of my EDF and ran it out the back with a slight taper. Once everything was put together, I trimmed it up flush.

 

[Hineybadger]

would this be a good first edf?

Search for the Grunjet. It's great for a 50mm EDF.

It’s a pretty easy build and mine flies great. I did have to put the battery WAY up front to get it to balance.

on a 50mm EDF end of thrusttube should be approx. 45-47mm opening on out. This measure is more specific needed for best function on 5/6 blade rotor...... than on eg. 12 blade rotor.

Im assembling the plans and I wonder what this is? (It’s the box with the blue circle)

That is the shelf that the electronics sit on!

@TB__RC i say go for it! it's just foamboard, but you do need to make sure that the airplane is balanced. A little noseheavy is a good idea.

I’m going to use a 1500mah 4s you think it will be good? And I’ll use 6gram servos in the back and 9gram servos in the wing

Yeah! That's the same battery i used on mine, just make sure the C rating is higher (not like 30) and i've used 9g servos for all 4, so you'll be fine with 6g ones for the tail.

Yeah they have 100c so I’m good (it’s This battery)

What are these for?

Remove the foam and slot your spars into those rectangles.

 

[TB__RC]

I see

 

[TB__RC]

Is this ok?

i didn't fold up the flap at the egde i cut it off.....

Done! The tail has a little to much angle because the fuselage had that angle but it may act like dihedral. The wing has a slight down angle I don’t know if it’s going to affect the flight performance.

Hey, just fly it and see how it goes. I know from building my first one it's an easy build. What's the worst that can happen, you'll have to rebuild a $3 plane.

It won't matter if there's too much tail dihedral. The wing should have a bit of dihedral as well, not anhedral. But i would echo

@chobson303's point. Just send it.​

 

[TB__RC]

I recommend some cheater holes. It's a lot of fun to fly!

Where are your “cheater holes”? I kinda made one by opening the wing up but I don’t think it’s going to help a lot

 

[synjin]

Mine didn’t need any cheater holes. Works great.
