3d Printed Part Sets - Freewing 90mm F-22 Raptor

Thanks, Gentlemen. Here is a small contribution from my side, the "nose gear brace".

Frank

Awesome! Thank you!

Steve,

On your original post it looks like you did the "Post Link" option (which is right next to the "Share Photos" button and also looks like a paperclip) instead of the "Upload Attachments" option which is on the right next to the Advanced Editor and Smilies buttons. Probably too late to go back and edit your post as the forum only allows you twelve hours to do so. But no worries, we have them attached now.

And once again, thanks for creating and sharing these files!

I have only ever used the upload attachments button but I have tried two times in different browsers to attach the files again and it only lets me insert or remove them individually and in the same way as my original post. Here is an example. Not sure what I am doing wrong here.

May have just learned something here.....are the files in my previous post accessible?

Yes, they are! Thanks!

Here is the first part to improve the airflow in the inlet ducting, a fairing to transform the tube holding the wing spar into a tearshape profile. The second part I'm currently working on will provide a sharp divider in front of the fan.

And a report from Scale Police: The Stars n' Bars insignia at the fuselage sides and at the wing bottom are painted in a darker color than the surface below (i.e. the decals on the model are wrong). Only the one on top of the wing comes in a lighter color, which is correct with the stock decals.

Love it!! My nav lights are not scale at all!! Just where I thought they look cool.... However, on my serious scale projects, a rivet out of place is just not cool at all!!! LOL Glad you are here on the Squawk. Rheinland rocks!! Jerry

[RCjetdude]

Yes, they are! Thanks!

Excellent! Thank you for the feedback.

Here is the second part to improve the air flow in front of the fan. I made similar parts for the Lippisch and the L-39 (divider only, no spar fairing necessary on the Albatros) with noticable performance improvements. Due to the poor weather here I won't be able to do flight-testing in the near future. Happy New Year!

Very nice! I'll have to print those up for my second Raptor!

Frohes neues Jahr!

[downwindleg]

Yes Radarguy, I will be very interested to hear about any increase in flight performance/effiency. Very cool indeed.

[crxmanpat]

Got mine printed while I was at the field today. Came out realy nice! Now I just need my replacement plane to show up...

Thanks for your efforts!! I get the notch over the tear drop fairing but what is the big rectangle part on the sharp edge of the divider?

There's an air duct there in the foam. See this pic.

[downwindleg]

O.K. now I get it. Thanks Pat.

[Radar-Guy]

This is how it looks from the other side. The opening in the foam needs to be enlarged a bit.

[crxmanpat]

My dividers came out great! Thanks Radar-Guy! (I'll be printing up the nose gear brace too!)

[RCjetdude]

Here are the TV plates I designed for the Raptor.

What are most of you using for a 3D printer? I'm starting to think seriously about investing in one but don't want to drop my life savings in the process.

[crxmanpat]

Prusa i3 MK3. I love this thing!
