Default Park-Flyer Voyager?

Hello Cityflyer, Welcome to Wattflyer!
I'm not familiar with that plane, but from the specs it appears that one of the many "300" size brushless replacement motors will work. This would be in the range of 65-90 watts output.
I went to the Graves R/C site and found a couple of choices. I'm sure they have many more, but these will give you some idea of the price range and general size;

And a good 15-18 amp ESC. I realize they recommend a 10A ESC, but my experience has been it's better to go a bit oversize with the speed controller. http://www.gravesrc.com/CSETB18_THUN..._p/csetb18.htm
That is the "High" end of the price range, here's the "Budget" end;

And a speed controller;

Here again I've added about 50% to the recommended rating. You will get other opinions on this, but most agree it's far better to be "Over" size then under.
Regarding speed and torque for each motor, you can control this yourself, by using a 2s (2 cell) LiPoly with the recommended prop. You will see on the motor specs this will be a larger prop than that recommended for a 3s.
This will yield a slower flying speed with plenty of torque.
Last, you could take a trip to Graves with these suggested choices and see if they have other recommendations.
For batteries, I'd suggest sticking with major brands and use a 2S LiPoly of (about) 800-1200 Mah.
Good Luck!
Ron
