RC F-15 C/D/E twin 70mm / 80mm EDF Retracts

Hi,
Thank you very much :-)
There is a smaller F-22 in my designs.
But you may be lucky.
I'm not entirely sure yet, but my next project might be a larger F-22 with vectored thrust, since the small one flies so well.

And that, my good sir, would be a dream come true.
I’ve seen those smaller F-22s, but they just aren’t enough for me. I’d love an F-22 as complex and complete as this F-15 — and I’m sure many others would want it too, I promise you.
Please, brother, I beg you — please! I can’t express how happy I’d be to pay you for that work.
About the same scale, landing gears, optional transparent canopy, two 70mm or 80mm engines... Just perfect — exactly like I know you can make it.

Hi, Thank you :-)
Thats a great honor!
I would be very happy to see some pictures of it.
The Scale is 1:12.67, but you can scale it up by 105.57% to get a scale of 1:12.
If you dont install RC Parts thats works fine.
I vacuum formed a 0.7mm sheet of PVC - ther nessesary plug is included.
Best regards, Simon

yes I will share once I complete it. it will be a display mainly so no rc parts will be required, unless I do one for me. and thanks for the scaling percentage. will be purchasing this file soon. Thanks for the reply!

forgot to ask do you have one that has GE engines? Qatar uses GE motors not Pratts. Thanks.

not yet.. maybe in a later update

Thanks :-)
20% heavyer shouldnt be a problem with two 80mm fans

Hi Lazar,
No problem i will refund it for you.
I hope the financial situation calms down again.
All the best
Simon

Hi there,
This part fits into the cutout between the airbrake and the EDF. This cutout is a bit large, and this part serves to make it a bit smaller.

But it's not necessary.

Hi,
Thank you :-)

In principle, the active variant can be realized with a bit of tinkering, I think.
The two inner pylons for the E variant are included, the two outer ones for the EX variant are not.
The nozzles for the EX variant are also not included.

hi there,
Unfortunately that will be very difficult.
Most parts are designed for 200x220x250.
That means they would have to be cut again several times

Good day,
Thank you. This is a great honor.
Yes, sure you can email me [email protected] or send me a direct message here. what ever you prefer

Hi there,

Sorry, I only saw your comment now..
I used an Ender 3 and a new a K1 Max to print my models.

I can give you a profile but it depends a bit on the printer.

I would first set the extrusion/temperature correctly
https://colorfabb.com/de/how-to-print-with-lw-pla
and next take a normal PLA profile and adjust it.
The settings from above.
Speed ​​not too high 50mm/s for starters and retraction disabled.

So it should actually work well

Hi Altsi, I am going to your files: this F15 is amazing.
I have a K1 max too and normally I print with Polymer Polylite LW-PLA and also with ESUN LW PLA:have you profiled for K1 MAX for these materials ? I see that you are using Colorfabb: is it mandatory or alternatives as the ones I a using can work ?

Hi there,
Thank you :-)
I didn't provide printing profiles with this model.
But of course other LW materials will work too.

Thanks for the tip.
For some reason the zip file was not ed.
It should now be there.

Hi Growler,
Thank you :-)
Yes, the ducts are moved further inwards and are L-shaped.
It was quite a challenge, but I made sure that the cross section remained the same.

I am curious though, how much flight time are you getting out of a plane like this?

3 minutes+ with the recommended setup

Thanks :-)
Yes the nozzle is a bit of a torture for printers..
you can print them in normal PLA.. the weight should be negligible.

For the gears..
Luckily i 3d scanned them..
Axle to axle it is about 10cm. Wheel diameter is 6cm.
But the wheels are rotated about 7° (underside inwards when retracted).
I can the scan if that helps

Hola! Si sería de mucha ayuda. Gracias

I was more interested in how high the chassis leg is, etc. so that I could know what other chassis to buy. Aliexpres offers more types and sizes

Or, has anyone tried to print a similar chassis?

Not that I know of... but I wouldn't print the legs either.
That's too weak.

the main landing legs are from the upper end to the axle is 9cm, the wheel is about 6cm in diameter

the front landing leg is from the upper end to the axle is 13.4 cm, the wheel is about 4.3 cm in diameter

Aliexpress offers this, for example, but there are multiple versions and each has a different size, so which one to choose?

Or from these. That's why I asked about the dimensions

It's a bit difficult because, as I said, they are twisted and inclined.
But the right ones are available here under spare parts:

Hi there :-)
good to hear.
I wish you much success with the construction and later with the flight.
If you have any questions, of course write me.
I'm happy to help
Greetings from, Switzerland :-)

Hello again! ^_^
I have a question before starting to print this amazing F-15. I know you strongly recommend printing it with LW-PLA. However, if LW-PLA is not an option, what type of filament would you recommend instead?
Is it feasible to use PLA+ or normal PLA? I understand it will be considerably heavier, but can it still work, especially with the 80mm engine option?

Thank you in advance for your advice!

I haven't tested it.
It will probably fly with 80mm...
but it will be extremely fast and landing will be a big problem with such a large weight.
I would not recommend to print it with PLA or other not LW materials..
The model is designed for LW-PLA or LW-ASA

Will you PLEASE build the F-22 Raptor with a similiar size of this F-15? PLEASE??
I will be the first one to buy it

Hi,
Sorry for the late answer.. i was quite busy..
yes the lengths for the optional carbon tubes are missing. you are right.
Rudder 28cm
Backwards fuselage 37cm
Wing 45cm
I hope that helps.

Best Regards, Simon

Thank you very much.

And it'll help too in the version organization!

Hi there,
Thank you.
As far as I know, they should be ed as a single ZIP file when you click on "" (on top, next to the price).
Or am I completely wrong?

Sorry you are right.. looks like Cults changed that :-/
I will all files as one zip.
It is very annoying

i added a single file with all the parts

It is designed for 220x220x250mm
Maybe you can get away with 200x200 for most of the parts.
But 227x148x150 is defenetly to small, sorry

it is designed for 220x220x250mm or larger printers

Ok thanks

Hi there,
Nice to hear and thanks for the hint.
I didnt try CF filament yet.
But yes it looks like a great alternative to ABS. ABS is very difficult to print without enclosure.

I am not d at all with Esun just amazed at how simple it is to use and I can send progress photos to show the finish as I complete those parts but for starters 35 mm of the nose cone is CF

Of course, you can scale it up.
the 70mm version by 150% or the 80mm by 131%.
However, keep in mind that the specified retracts will then no longer fit.
All carbon tubes also have to be larger and the servos have too much space, but that shouldn't be a problem.

I already know of 2 people who enlarge it by 150%

Daym, I would love it to have fully functional mechanization, i also have components for them, would it be possible for us to make a new custom from the cad file again? I think it is possible to keep it to a similar wingspan without needing to make it significantly larger :))

Thank you too.
The printing and building will also take time, no rush :-)

FPV would certainly fit in of space, yes.
I think this can be done with a little tinkering without specially adapted files.
At the moment I still have a lot of other things to do.

Awesome! I’m excited to start this build with an FPV setup.

Thank you, you are welcome :)
