FTFC19 - April Showers by Kilroy07 - Polaris

[kilroy07]

Okay, Foamy jeered me into it!

"Let's do this!"

The Polaris has been hovering around the bottom of my build list for awhile now.

It seems to be a very popular design, or at least it used to be.
And apparently usually made from depron (Which... I don't know, can we even get it here in the states?...)

Anyway I've found several examples of plans;

and FT even did a video of them back in the day!

I even founds plans on parkjets (surprised my account was Still valid, must have opted for the year long membership.
http://www.parkjets.com/

But in all cases (At first glance the parkjet plans are just a reprint of the RC group plans...) they don't seem to be for DTFB...
So I think I have some work to do on the plans as I pull them in CAD to make the laser cut files... So there isn't going to be pics of build progress anytime soon.

My plan is to go ahead and use DTFB and minwax it (unless someone stateside knows where I can get depron for a decent price....)
I also plan on using the white (foaming) gorilla glue. this will add to the build time, but I think the strength, lightness and water tightness will be a benefit.

So, more as this project progresses... (Stay tuned.)

Woohoo!!

Awesome!!

jpot1 did a FT style Polaris https://forum.flitetest.com/index.php?threads/polaris-ft-mini-style.57153/

@kilroy07 check out my thread. I did a mini size that may help you out that is set for DTFB.

I did see your post. I apologize for not mentioning it!

I'm defiantly going to be looking closer at what you did as I get closer to starting my build.

 

[FoamyDM]

Kick butt! I'll be watching
Can you put a pic of the craft in first post?

Now that is a cool plane. I was just thinking about nacelle mounted tractor props. What's the rule of thumb for thrust angle on a setup like that?

As I understand it, since the thrust line will be above the cg line, it need some down thrust. I believe that is already accounted for in the original plans.

SO... How's It coming?

 

[kilroy07]

Have not started.... 😔

This one might slide as I’ve been on the road quite a bit for work lately and when I’ve been home I try to make a dent in the honeydo list....

Haven’t written it off yet, but now that I’ve gotten back to the SR. That might be on my bench for awhile.

Shame. This is a plane I built from plans after the original article in rcm a million years ago. Would love to see one out of fb. Wish I had the time, still too many projects on my bench.

 

[kilroy07]

I haven’t abandoned it... I’m just in triage mode for Flite Fest the SR and two other projects need to take precedence.

I here ya! I have a giant scale Pitts on one bench I am finishing, and a giant scale ARS on the other I am rebuilding the belly after a very bad landing. Then there is the stuff to fix from the winter. Should be ready to go by the time the snow flies again lol
