Mighty Mini Nemesis 1.1

[Matagami Designs]

You've got me thinking about a 40" wingspan Nemesis, with the C-pack radial.

Wonder what the percentage increase would be? I calculate aprox. 165%.

Yep 167% or so. The issue would be the cowling and its interaction with the motor and bolt spacing. If you want to try I can redo the cowl to work for that size. I'd probably make a scalable version with a separate mount that can be glued in for different motors.

That would be cool. I like the integrated cowl/motor mount. Also, would it be possible to take the trailing edge of the wing tips down to a point?

So not sure how well any of this will print. I already scaled the power pack C mount up 167% and moved the motor mount back but the way I designed this print the walls are going to get thick so it will be a bit heavy. If I were to start from scratch it would be a different design for single wall printing but I suppose a little nose weight wont hurt. the other parts should scale ok. Let me know if you go forward with making one of these.

Awesome! How many sheets of foam did you need? Can't wait to see what you do with this.

It took three sheets. Bad news is my 3D printer stopped working.

Bummer! What kind of printer? Any idea why it's not working? It just dawned on me that I should have adjusted the back half of the cowl back down to the size of a sheet of foamboard after scaling it up. I will adjust that tonight and re-post.

Printed my parts on the weekend, Build at original size starts tonight. @Matagami Designs great job on the 3d stuff my friend, everything printed great, cowl is really nice.

I've updated the C pack cowl in the previous post so it should mount flush with a single layer of foam. Good luck with the build @Ratcheeroo !

Flash Forge Creator Pro. It has dual extruders... one quit working a while back so I've just been using the other one. It quit printing in the middle of a print. Filament not stuck. I think the extruders have gone out. Not sure, I will have to take it apart and see.

If you do, let us know. I am wanting to build a 40" version also with a EF1 pylon racing motor. It should haul the mail!

The cowl posted in #43 is for a 40" scaled up version and designed around the FT c pack motor. I don't think a scalable version will work due to the way it steps down the thickness of foamboard for mounting. When you adjust the scale this dimension needs to be constant. I think a single layer 40" version is still possible with a different motor mounting. In theory It would give more adjustability. What size motor are you looking at exactly?

Cobra EF1 racing motor. They call it a 2826, but the can dimensions are 3546.

Wow, thats a little pricey. Nice but expensive.

I wouldn't buy it just for a foamboard airplane, but I already have it out of a race plane I have. Just want to see what it can do.

Any update on this build? Did you get the printer fixed?

No, printer is still down.
