Default Junior 60 - what kind of brushless motor?

I just bought a Junior 60 without electronics. What kind of brushless motor should I put in the plain?

Without more information about the airplane, there's no way to narrow down the field. Can you point to a website with the specifications? Better yet, can you post the specifications?

Quite literally, there will be dozens of different motors that will work equally well, once we figure out what the power requirements for this plane are. It'll boil down to things like quality, reputation, etc..

Well, I decided to just install the AXI 2814/12 Motor with controler Jeti advanced 40amp. Lets see how it will work.

I never saw your reply before...

What battery and prop are you planning on using? How did you come to decide on that particular motor?

The best output from that motor is about 250 Watts on a 10-cell battery with a 9.5x5 prop. That'll give you about 50 Watts per pound per your earlier specs. Should be okay for a old timer, but you might be left wanting more power.

Well, the motor was recommended by a friend, with an APC 10-7 E prop. I have already experience in soaring, but this will be my first motor plane with which I want to make a relaxing flying. In your opinion can it be a right choice? And should I go with classic battery's or with the new PoliLypo?

LiPoly will certainly up your Watts-per-pound figure due to their reduced weight. It's up to you, though. LiPoly will be more expensive, and more sensitive to newbie battery abuse... You'll either want a 10-cell NiMH pack, or a 3S LiPoly.
