Just about have my Polaris finished, came in a bit heavy and was unable to use my lighter Thunder Power 1320 for a battery but have ordered a 2100 which should balance the model out nicely. One question is the bottom of the Nacelle and rudder sanded to a rounded shape ?
Thanks. RMac

Yes, very true. But I've also pushed a couple of projects back to work on the Polaris. But sadly I've taken on another project that I had just finished this evening.

Looks Great - very Sci-Fi!

Looking forward to seeing it in person.

Now I will work on the body artwork. I'm thinking camo would look great on this plane.

I think the 2805 might be a little weak for ROG and ROW but it might work for hand launching and slow flying depending on the weight of your Polaris. I would go with a stronger motor.

Did you even try google? I typed in CF 2805 and got pages of hits, including the Emax site.

Looks like the ? is what KV rating yours is. Prop size on the motor is a hint.

A rough indicator of motor power is weight. This one weighs 25g, while the standard Polaris motor is 48g.

Take a look at the Polaris EX on the ModelAero.com site. That's the way to arrange things for an EDF unit. The EX configuration is much simpler and more effective than trying to build the fan into a DC-10 style nacelle as part of the vertical tail.

I have the Polaris EX with EDF and it flies superbly.

Polaris Pictures

Just completed my second Polaris using Steve Shumate's plans. Most of my flights are off grass but at our last float fly, flying off water was easy to control and gets airborne quickly. It is fun to fly fast like a jet or slow with excellent control. Landings are slow and easy, just cut power and glide in.
Polaris #1 built in 2013 was decorated with colored tape and had many flights. It was destroyed on a nose into the ground when the elevator horn came loose on the back side of a big loop.
Polaris #2 was just completed with decals custom designed from Callie Graphics. I wanted a highly visible decor. I first brushed the 6mm Depron with water based acrylic then sprayed with yellow Krylon Paint for Plastics.
Battery and ESC are up front, cooling provided by inlet slots in canopy with outlet louver behind it. Sealed front section to withstand some water. Have many assembly pictures for anyone interested in receiving.
