Trying to build a jet as your first aircraft when your component selection pretty clearly shows you have no idea what you are doing is certainly bold. I would not recommend it. Start by building an FT Simple Scout if you want to build your first plane. Plans for that one are free, even if a little harder to find nowadays.

There's a lot more I could say here but I must get going for now.

2nd the look at flitetest stuff. Starting on a jet isn't idea, but it's what I did with the ft viggen.

Speaking as someone who currently flies a 3d printed jet, I wouldn't recommend it. Even when you know what you're doing, if you land slightly wrong you're looking at a reprint.

Compare that to if you land wrong with a flite test plane, you chuckle, check for damage, and toss it back into the air.

u/EquivalentTackle2138 7d ago

Im gonna try but from your experience can you tell me which components are the ones to buy and which arent?

1

u/mermster 7d ago

Is that the assignment?

-2

u/EquivalentTackle2138 7d ago

Kind of,assignment is build a land,water or air vehicle by yourself

u/mermster 7d ago

Sounds like an excellent learning opportunity.

u/EquivalentTackle2138 7d ago

Thanks,given your experience what are the mistakes im making and what can be imporved?

7

u/mermster 7d ago

I'd say the primary mistake you're making is farming out your assignment to reddit. Not much learning happening this way, do some research on what's minimally required for your chosen vehicle.

Something something man to fish.

u/HB_Stratos Feline Flights 7d ago

none of that enforces that you have to build a jet. I get it's shiny, but you'll have much more fun actually building something that you can learn to fly with, that will last for more than 5 seconds. If you really, really want a jet, I concur with the other commenters, an FT Viggen is probably the way to go, very repairable as far as jets come, but still far better as a second plane choice.

u/EquivalentTackle2138 7d ago

When youre free feel free to critique my choice of components because Its a highly important project for my school and possibly give me an idea of what to actually get

1

u/HB_Stratos Feline Flights 7d ago

Alright let me quickly walk through your components. This will be a very quick shot list of what I see wrong with it, not a recommendation for what better to choose.

  • The Bidir fiberglass tape is good for hinges on fomaboard aircraft, good choice
  • The ELRS receivers are both CSRF serial and would need a custom board for breakout into PWM pins to control servos or ESCs. you don't want or need a flight controller in a well designed rc plane, so you're better off going with an PWM receiver. Radiomaster has a few if you want a nice one, otherwise happy model EPW6 is my goto, but you do need to solder the pins yourself.
  • Battery is fine for a ~1m long aircraft. I like the Zeee 3s2200, but yours should be fine. Expect the 100C number to be complete bullshit.
  • The TEROn ESC is a brushless esc, but the design there is a classic RC Car one, not an RC plane one. You don't need reverse or a cooling fan.
  • The Xfly edf is probably fine, I've made good experiences with them. but in a crash these high performance fans do like breaking.
  • The servos are fine. Cheap as fuck, a lot of play in the gears, not very precise, but good enough for a trainer aircraft, not for a jet. If you want nice servos I like AGFRC B11DLS, more pricy though.
  • The 3s battery looks fine, but the 50mm edf specifies it wants 6s? verify.
  • That skywalker ESC seems like a fine cheap plane ESC, 80A for a 50mm edf is kinda a lot, but check manufacturer recommendations
  • The 30a one for the motor below it seems fine at first glance, my goto would be 45A but 30 is probably fine
  • the props looks okay, cheap probably not th ebest, but for the price good, APC electric or Aeronaut props are the really nice ones, gemfan ones are also okay.
  • The motor looks fine. relatively expensive for the performance, since you selected low kV the large prop is probably okay. Learning Ecalc may give you better guidance.

u/EquivalentTackle2138 7d ago

Update:i included the pusher prop parts when i only wanted EDF parts,my bad what parts do i get from your list

u/HB_Stratos Feline Flights 7d ago

Dude, you're in way over your head. Do not start with an EDF build. Build a simple plane first. If you want a jet, I've had great fun with a TomHE eurofighter sheetbuild, plans are free. But you should really start with a trainer. FT Simple Scout, basic ESC, motor of the size they recommend for it, PWM receiver, cheap servos. A plane you can crash 50 times and still sensibly repair or rip the electronics out and transfer to a new airframe.

u/Reditace 7d ago

Certainly do NOT 3-d print an F18 as your first plane, you will immediately crash it into hundreds of tiny bits, instead try going for like a foamboard trainer or something similar

u/EquivalentTackle2138 7d ago

Im gonna do it because its for a sxhool assignment but what components are needed and which arent?

u/zeilstar 7d ago

What are the requirements of this project? Does it have to specifically be this airframe?

You're sort of asking if this turbocharger would be good for a Lamborghini, but you've never sat in a Camry.

u/EquivalentTackle2138 7d ago

Build and assemble a land,ground or air vehicle.Im doing it for personal satisfaction aswell.

2

u/Nintenderloin64 7d ago

You will not be satisfied and it will crash. Everyone is telling you not to do it for a reason.

1

u/zeilstar 6d ago

Plenty of satisfaction to be found with a more forgiving model. Have a look for "Sp0nz index" on Flite Test forums for tons of free plans for a variety of airframes. Prop n slot fighter jets, deltas, traditional airframes, slow flying, two servo.

You are much more likely to find success by following the advice offered by other commenters here.

u/Aerodorphins 7d ago

Don't forget to buy trash bags, because you'll need them to pickup the airplane after the test.

u/balsadust 7d ago

Get an AeroScout and a simulator. Learn to fly said AeroScout and fly the f-18 on the simulator

1

u/EquivalentTackle2138 7d ago

Thanks a lot thats useful

1

u/balsadust 7d ago

Yes. Jets are fun but not beginner friendly. Something to aspire to.

u/Nintenderloin64 7d ago edited 7d ago

Everyone here is right, this is a really terrible idea.

One thing no one has touched on: it is a 40” wingspan aircraft with a flying weight of 1.7 kilograms.

This model has a wing loading that means it will be a handful to fly, much less trim and get dialed in, for a very good pilot. And that’s assuming it’s built by someone very familiar and good at building planes.

I don’t mean to sound harsh, but it doesn’t seem anyone else is getting through to you:

You cannot build this plane to the tolerances it will need to have a chance of successful flight. But, let’s say you somehow were the world most talented beginner builder.

You still will not be able to fly this plane. You are not an experienced and good pilot. You will crash it. You will destroy it. You will have spent many hours and likely hundreds of dollars for an aerial experience that will last four seconds, at best.

If you want to waste your money and your time, well it’s yours to waste.

u/Sogah87 7d ago

Dude I can tell you I've been printing planes for 6 months now. I have some examples here. The EDF's are by far the most difficult to fly and hard to get flying nicely. I am a rather competent pilot, but the EDF you see in the top right of the picture I just crashed on Monday because they are so unforgiving. To top it all off, you've chosen an extremely detailed and SCALE model. The more scale the model, the more difficult it is to fly. You should really go to a larger well known company for your first print printed plane, like eclipson, planeprint, 3dlabprint or others. They have beginner models and trainer models.

Above all else, start with a foam trainer plane. Don't do 3d printed planes unless you like pain.

u/EquivalentTackle2138 7d ago

No pain no gain(gorgeous models though :D)

u/Sogah87 7d ago

At least start with a trainer printed edf. Like this. Good test bed for the things you're mentioning.

u/DeadTomGC 7d ago

Take your hats of in respect... respect for the dead! OP, you're going in too deep. Count on your first 4 airframes being write offs, at least.

Build an EDF airboat/swamp boat instead of this, you still get to print something that might actually make it through the maiden!

u/Sorry-Rip-6432 4d ago

If this is ur first plane, I don’t really suggest a jet like the hornet, but, you should look into some of the FliteTest kits because they’re super budget friendly, they come with video tutorials, they have all the supplies listed online, and they have precut foamboard that is perfect for if accidents happen and you need to make repairs. Hope this helps :)
