Kitting and shipping is a whole art form unto itself. Changing spar sizes so you can utilize the whole piece of carbon (making an elevator connector 333mm instead of 350mm so you can get 3 from a stick without waste). I had 30" boxes made because it fell within dimensional weight restrictions and 36" did not, saving me $1+ on each package. Then you need to look at fitting the kit into it and sometimes that means splitting a long part. I understand your reasoning quite well and think you made reasonable compromises. Good luck kitting the plane. There are "tens of dollars" to be made

With 2019 shipping costs being what they are ,
certain compromises must be considered to reduce overall costs.

My thinking was to ...
1. put the Wing Split INSIDE the fuse and out of sight.
2. fit in current packaging
3. accommodate the original designers CF sparing scheme
4. glued joints tend to be stronger than continuous material IMHO.

Re fuse alignment modifications:
I have found that tab&slot assemblies tend to droop between tabs unless preformed.
Thus I choose to employ the uniform and higher number of tab&slots.

My preferences in the Polaris family are:

1. Polaris EX — motor mounted above rear fuselage, twin booms.

2. AquaCat — swept wing derivative of Polaris with twin booms.

3. Classic Polaris

I very much like the twin boom designs for their enhanced directional stability, which helps smooth out big open maneuvers. Also the Polaris EX motor mount reduces rear fuselage breakage.

Unfortunately my EX was destroyed in a radio-related crash, but I plan to build another. My AquaCat was a victim of an attempt at Limbo; the pole sliced it in half!

Thanks for the comments and suggestions.
re Tons of $$$ ... I FEEL the Sarcasm and concur.
No doubt a reason for Aero's bow out.

My aim has been to Keep the original Polaris alive because I "Just" missed out
11 yrs ago when it 1st came out.
I had an Original Northstar back in the late 80's when it came out
and I was living on a small lake in Michigan.

Now I see an opportunity to contribute again and make some changes of my own.

The EX and Aquacat are more Aero's designs .

I have something similar already in Lockey's Vixen.

Tony is a good friend and designer.
We spent nearly 3 weeks with him last Jan-Feb in NZ and Perth Au.
I actually go t to fly in AU too.

Not to mention my plate is quite full of late.
Maybe at a later date I could consider doing those with permission of course.

People look at you having the capability of cutting a kit and never see the behind the scenes stuff and think they package themselves and mail themselves. Nothing about floating inventory but be sure to ship mine within 24 hours... I just literally spent an hour cutting and bundling CF parts for some of my models that I need to package for an event the end of the month. I'll be polybagging them early next week. The struggle is real

You've been at ti for a much longer time than I.

Also far more ambitious too.
I'm too old to "struggle" or maybe too lazy ;>}

I just do this for fun , keep my skills up and to stay "relevant" .

My stock is Foam, Ply parts, Shipping boxes, tape & labels.

I can QUIT on a moment notice.

Best of luck with your Event orders.

My local club treated me with disdain and apparent jealousy over my
private flying Field and shop.

So I just fly with friends.

Hi Bob,
Sorry for the delayed response, been out of town the past week. I responded to your PM, but for everyone's benefit I would be fine if you offered laser cut kits of the Polaris. I'm just thrilled to see the design live on!

Well, it finally happened, after 11 yrs, I get to cut the Polaris kits.

Steve just gave me the Oky Doky !

Here is my reply to his PM ...


Thank you very much !

What great news.

Happy to keep the Design Live
,was my only goal too.
I am happy that you feel the same way.

I had a Northstar built from scratch back in the 80's.
Had a hot .40 motor on and it was Very fast and a great sight to see at the
lake where I lived in Michigan.

Thanks again.
Best regards

What does it use for wing spars? I presume they are not included.

I am using a 5mm lightweight tube for the cross spar and a
smaller CF tube that I dug out of my personal "stocks" which
is long enough to do both the wing as well as the Hstab.

I'll measure it if you next time I'm out in the shop.

I suppose that the diagonal wing spars could be left off.
I believe that someone claimed that the design didn't really need the Cross spar either.

I wouldn’t like to try it without the main spar, especially with MPF being more flexible than Depron.

The Polaris Mini dispenses with the diagonal spars and has ample rigidity so maybe the Polaris can manage without them.

From all the chatter here

I am thinking that I am the LAST person on the planet to be building one of these.
I had one back in the beginning and now I'm building one from my NEW cutting files from MPF.

But, I see now that I will be sharing it With Myself. sigh ... yeah yeah wha'd I expect to happen !

Oh well, nothing ventured nothing gained,

Besides it is time for guys to get their Halloween builds going on the Flying Witch or Man On Broom.
Like ... I got two orders just this week.

Not the last, guy, I still haven't built one, on the list, but too many already cut and waiting for somebody to glue them up!

Yes I too am a victim of having too many choices and too many dreams and too many Cut and ready to assemble kits.

Oh, Poor, Us ... boo hoo.
Shame on us for complaining about our spoiled rotten situation.
We're starting to sound like millennials FGS !

OK OK OK it appears that I am about to get my 1st order for a Polaris . Maybe ;^}

BTW I got my foam order yesterday ! Yeah ! and thanks.

Cool, glad it got there ok!

Incidentally and off topic have you checked out this thread lately?

Even more to "boo hoo" about and be ashamed of our excesses.
