Many Thanks

Here's mine, I'm kinda a bad painter but I think it turned out alright. Powered off of an F pack equivalent with thrust vectoring, and it flies beautifully. View attachment 183084 View attachment 183085

Howd you thrust vector it?

Is it possible to scale down to a 50mm edf

 

[Proptastic]

Yes print the plan at 71%-72% should make the holes right for 50mm.

It would have almost a 20" wingspan so it's like FT Mini Raptor size

Thanks !!

Zero clue where I got the STL from because that was 5 years ago lol. If the thrust vector bracket is not earlier in this thread then I probably just found the bracket on thingiverse somewhere.

OK is it thrust vectored on pitch and yaw or just pitch

I did my Viggen with a 64 mm EDF with a Thrust Vectoring Nozzle for 2 axis. If you go down to a 50mm, doubt that you could find a 50 size TVN. You would have to make one.

A 2 axis build TVN (elevator and yaw) is a pain to make. Used that on a modified B2 Spirit. Better off just putting a vert for yaw inside the duct.
I position the EDF forward enough with TVN at end so that I did not need up canard and got it re-zero. Since the wing is so large rolling was very slow. I put 2 servos(one in each inlet duct) to activate additional roll and pitch from the canards but found out the Viggen would be much better with an 6 S 80 EDF. Pics available.
