Good evening to you all !!

Just a motor question.
Last week I went to a Hobbystore to buy all the electronics.
There I show the construction guide and the tip to take a 240 watt motor.
Two people are looking with really big at me and say, "what, 240 watt ?"
They showed me a 240 watt motor and it was a really big motor and then they´ve given me this:

Magic-Torque 15-14 motor
Magic-Speed 18 controller
APC 7" x 4"

They told me something about 130 watt and that will be enough.
Please help, I´m so confused. What´s right and what´s wrong ????

Always trust the designer of the airplane over the hobby shop owner.

What Steve states in the construction guide is exactly what you want. I'm afraid 130 watts won't be enough. I would see about returning the motor and get what you need. Good luck.

PS-I do have the correct 2212-6 motor in stock but I encourage you to work it out with your local hobby shop.

try www.rctechnics.eu


they got the 2212-06 for 17 euro or so.
A 25Amp esc will do nicely with a 6x4 prop, gives 600 to 700 grams static.

Glad you like it! Yes, this model takes a lot longer to slow down than any of my park jets or sport RC models, due to it's very low drag airframe (no flow-through inlets!) and small prop diameter (very little airbrake effect). Thus, I have to think ahead when landing it and chop the throttle way earlier than I'm used to. To get that great nose-high landing attitude, you have to add a little power immediately after it slows down. Then you hold lots of back stick to keep the nose up and use power to control the rate of descent. Done right, you can drag the rudder through the water while the rest of the airplane is still up in the air! Great fun. It takes quite a bit of power to maintain level flight once the nose is really high, and it also makes some weird sounds as pockets of separated airflow from the nose and wing go through the prop. Doesn't hurt anything, but sure gets your attention!

I love Scott's comment on this ("Always trust the designer of the airplane over the hobby shop owner")!

Scott's right--you need more power than 130 Watts for this model. It may fly with that motor, but will struggle to get off the water and will just be lethargic when cruising around. And aerobatics will be out of the question. One of the keys to the really spectacular performance of this model is the very high power loading (combined with a very low wing loading). And since the recommended power setup is so inexpensive, there's really no reason to skimp. The 2212-06 motor is easily available pretty much worldwide, so I'd recommend just ordering one by mail if you can't get it locally.

I love it! A living room floor demonstration. I want see some video of it taxiing around in your living room next. If you hold a little down elevator to the lift the tail and then give it some rudder with a little throttle, it should pivot pretty easily in your living room...

I'm really glad to see some other guys building this plane. I really love the way it flies.

Spectrum receiver waterproofing

Got a question one on you Polaris flyers might know.

I'm flying with 35 MHz equipment at the moment, but have a lot of trouble with glitching (not just with the polaris, but with many planes), so want to upgrade to a Spectrum system.

I've been reading a lot of people waterproof their receivers with corrosion-X (or similar)

Anyone used this on Spectrum receivers ?
I'm thinking the 2.4 GHz might be more sensitive for any coatings (like corrosion-X) on the electronics then a normal 35 (or 72) MHz system.

Regards,
Wilco

I use CorrosionX on both my AR6100s and my AR7000 Spektrum receivers. They work great even after dunking in the water several times. Saturate the inside of the receivers with CorrosionX and then let them drain on a paper towel overnight.

Kits are almost done!

I'm happy to announce that kits for the Polaris are just about done and should be available very soon. The vendor will be Model Aero, who's a big sponsor of RCGroups and already produces a great line of innovative high-performance foam aircraft. Here's a link to the Polaris page on their website:

http://modelaero.com/Merchant5/merch...tegory_Code=AM

I was excited to work with Scott at Model Aero (known as galloping ghost here on RCG) to develop this kit. It was clear to me from the beginning that Scott is laser-focused on satisfying his customers, and he and I worked together to make several improvements to the Polaris design to make it even easier and quicker to build--without sacrificing any performance. I think folks will be very happy with the result.

More details will be available soon!

That's fantastic and the price is great too. Even my colors.
