Thanx SCott.

It's not quite a good as decals but ...
I had a lot of packing tape left over from a Sloper build that recommended the stuff.

It sticks on it's own but can be Mono-Iron'd to a better stick and even shrinks out
somewhat if you applied some wrinkles too :-)

Considering other excruciating methods of covering foamys I'm like'n tape
a lot lately.

Birdofplay, I love the colors it looks very nice, myself not much progress but recived the motor/ESC/servos/EZlinks UHUPoor today, I wonder if the motor is overkill 90grams with the prop spinner nut and mount (Turnigy C3530-1700), it fills up the narcell, but this is 120% so what do you think?

That Turnigy 3530-1700 will fly your Polaris fine....

I'm using the same motor on a 100% Polaris with a 7x6 APC prop (the hobbycity clone), and it flies great. It will pull close to 30 amps, so make sure your ESC is up to the task as it receives no cooling inside !

Good luck !

Thanks, sounds very good, the ESC is Turnigy 40A so hope it´l work fine.

Edit: Same day so I continue here.

Done some on the motor mount today, intend to seal the hole with cables later, so if possible avoid water coming in if/when its laying up side down in the water . Mount of hinges/ailerons as well and of course I made three linkages while bending them, the first one without the plastic tube....
The included screws for mount the motor seems to be a little to long, maybe it´s only me but if not shortened one of them hit one of the cables pretty hard, it was exactly the same on my puddle twin motors, it´l work like it is I´m sure but for how long? sooner or later the screw will tear through the isolation on the cable..perhaps, see photo.

Shorten the screw!

I recommend shortening the screw, HurriHeli, or maybe a washer or two under the head till it clears the windings.
This exact problem cost me the smoke out of two ESCs before I figured out what was causing it!

Guys, I had the Same problem with other Hobby City motors.

In their defense I suppose it is hard to predict what thickness firewall and
hence what length of screw to provide. sigh ...

Hurri : that motor should make for Short takeoffs :-)))

Re maiden flight ...
Rain all day and for the next two days.
Local Govt just called everyone with Storm and Flood warnings
and potential Lack of emergency services due to heavy rains.
AKA if your low evacuate NOW !

Storm, heavy rain, flooding = ponds, lakes!?

Sounds like the land of endless watercraft possibilities!

If you are talking about the main wing of my 2X Polaris, it is 1/2" blue insulation not BlueCore or PBlll. My BlueCore and PBlll don't have much wave either because the place where I buy it let's me sort through the bundles and pick out the flattest ones I can find.

Steve or Scott
I just purchased the motor for my 2X Polaris. I got a Trungy 3548C with a 12x10 prop. Do you think this will be good? I still don't know what the AUW will be. My guess for air frame weight will be 3.5 to 4.5 lb.

Polaris #2 is coming along well. The second one goes faster than the first.

This one is going to get the Polaris Transport decal set and will also go with me to the E-Fest next month in Illinois. It's gonna be exciting to fly her indoors!
