Bill, the stock motor (Goldfire) is just a plain 550/600 class motor, nothing special about it. It has plain bronze bushings and small brushes. You can putt around just fine with this motor.
Please note: I said
retimed. Plenty of power then. And while it will putt around, it also has the power to go vertical. Granted, not far, but vertical, yes.
Batteries have come a long way in the 5 years since you've had your e-streak. You can have longer duration AND greater performance.
And I have bought more batteries in the five years I've had the E-Streak. And more E-planes. And more motors.
A cheap upgrade motor would be a Kyosho Atomic Force 17T. This is a fully timing adjustable motor with very large brushes and ball bearings for about $20. It lighter than the stock motor and will bolt right in. Runs great on 6 or 7 cell packs. You will need a higher current ESC than the one that comes with the e-streak ARF kit though.
My very first electric, a Liesure "Wasp," still flying after seven years, uses an Astro 05 motor. Except for a Norvel "Folding Flyer" with a geared 280 motor, all my E-craft have Astro 215D ESC's up to 8 cells, higher cell counts use the Astro 217D. And except for the geared 280 I have never bought a can motor for flight use that was not included in a kit.
I used to fly mine with a CEM FAI15 motor on 8 2400 cells. Fast and good long duration (8 minutes typical). If you want to go slower and stretch the duration that's what the throttle is for 
.
As I said earlier in this thread, I had the CEM 0506 cobalt motor in it, didn't use the power. That's why I put the can back in.
For the best of all worlds, a quality brushless motor will extend flight time and give higher performance at the same time.
My main attention is on piston twins, have yet to try a brushless motor. I've been really impressed with Steve Rojecki and his Hacker powered airplanes, though.
Small plane, electric does very well.
. big plane, cost goes up like H...
