nnMIG 3 Swappable - design, build, and review log

[jayz 84]

Okay it's official, I will be designing an A-10! I plan to finish the nnMIG 3 and then get started. I am really excited for the challenges this design will bring.

But to bring this back on topic - I think I'm going to use a different wing design for the MIG. I'm thinking about removing the under camber, a clean trailing edge, and adding an a airfoil to the bottom of the wing.

Thoughts?

Im all for removing the undercamber i found that it flys smother and not much in a float difference. And i was planing for my future builds to have a clean trailing edge. But adding the airfoil to the bottom hmm. Not sure how much it would help but im all for it, go for it man..

How did it perform on your clipped wing spitfire? It surely would be less drag and you are going for speed, right?

I can't wait to see how you handle the A-10.

I am going to try a Tacon 10 1100kv motor. This is the motor the guys flying the 40inch FMS Strega and Vodoos use at over 125mph. It should run about 1100 watts on 4S with a 10x10. The Strega is over 1500g at flying weight so the nnMIG 3 at around 1000g should haul.

Let me know how that Tacon motor works out and how many amps she pulls to see if thatll work when i start building full size plane. I just ordered the ntm EF-1 pylon racing motor with 8x8 props for the 800mm planes and maybe my rearbear

Is that a upgraded motor for the vodoo and strega cause if i remember right they come with a 3648 770kv

Hey so this motor is only actually about half as powerful as what I'm already using. Thanks for the suggestion though!

Not doing my research again.

Another idea I was thinking nerdnic what about trying to narrow the hole airfoil of the wing? there shape produces a lot of drag them selves. I bought that ef-1 motor and started looking at all the pylon racing planes like hobbykings Invictus EF-1 Pylon Racer. Check out its airfoil and how well all them planes cut threw the air. the only fun part about it is making it strong enough being only as thick as your servo(having the foam removed and the servo touching paper to paper) Makes me wanna highly modify a full size spit to try it out

I've been playing with this idea too. The aluminum spar I use is as thick as two sheets so if I cut a groove on both sides for it to sit in and then recess the servo on top and bottom the wing would be rock solid. Getting the airfoil right and reproducible will be the challenge.

It helped a lot. It's quieter and more slippery in the air.

8mm aluminum spar? Thats pretty big. I only use a 3mm on the 800mm planes. But i think im gonna give it a try i was think about doing it pretty much the same way you explaned.

So I worked on the wing design today at lunch and I'm gonna use a thin foam spar just as a former. I closed up the trailing edge and removed the under camber. I'm gonna print it out and test tonight and see how it goes.

 

[jayz 84]

That sounds good man let us know how it works out (waitin patiently)

Updated first post - added wing build log.

 

[jayz 84]

Now thats what im talking about nerdnic awesome job man. Guess you desided to go with what we were talking about making it a thin wing. How strong is it?

Ok now im getting impatient and excited i wanna build

Nice job on the wing. It may be involved but you know what they say... If its worth doing, its worth doing right. I like that you say it requires getting burned.

Attention: Blood sacrifice required

 

[nerdnic]

Thanks guys. The wing is rock solid, very strong. It's gonna take my 90mph u turns like a champ ;-)

I worked on the fuse plans yesterday and plan to get them printed and built tonight.

 

[jayz 84]

Thats great man i cant wait.. what gauge aluminum are you using on this wing so i can get it cut out tonight or tomorrow so im all ready to build

 

[jayz 84]

Hows the beta build coming along nerdnic?

where can you get foamboard by the box?

 

[jayz 84]

monterx7 you can order it on dollartree.com in bulk/box its called readi board

 

[JohnRambozo]

where can you get foamboard by the box?

I had a little trouble searching for it, so here ya go:

Sometimes I will call the local DollarTree to see if they have an unopened box that I can pick up. Then I don't have to wait.
