Great Planes Sportster EP

LJ gave me this kit for a Chanukah present.  I wanted something electric for getting in a quick flight now and then.  It started as an ARF (Almost-ready-to-fly) but I didn't like the color scheme - so I stripped it down to bare wood and re-covered it. 

Here's what it looks like from the manufacturer, before I modified it.  The pieces were completely covered in red when it arrived.

Great Planes ElectriFly Super Sportster EP ARF 48"

It took about two weekends to strip and re-cover it, plus the time to install all the gear - so instead of an ARF (Almost ready to fly) it's an NCR (Not close to ready.)

Today was the first flight.  It's a nice-flying plane, and it's all electric, so there's no oil stains in the car, no wipe-down after the flight.  Click on the pictures to see larger ones.

OK, so the stock power system was a little anemic.  Flew nice off pavement for 6-7 minutes, but not really what I was looking for - so after a few trips, it was time to go to Al's Hobby Shop.  I upgraded mine with an E-Flite 15 (Not the 25) and it's fantastic - Config is an

bulletE-Flite 15,
bulletAPC 12x6 E,
bullet4000mah 4-cell pack (TrueRC, only 10C rated, but plenty for this)
bulletCastle 45A controller.

It's still more power than this plane needs, but not ridiculously so. I keep it set so it draws about 400W max, and it's still got fast unlimited vertical, and I get TWO 10-minute flights per pack. And the setup weighs EXACTLY what the old setup did - battery's 1/2 oz more, and the motor's a little lighter.

To mount it, I just used a triangle to identify a right angle to the existing mounts, marked it, and sawed them off. I made a new firewall and mounted it to the sawed-off stubs, and the thrust line was perfect - see pix.

(Note - later I swapped in some plastic stand-offs and screws from the hardware store - about an inch each.)

This is a great plane overall - I've built it in the 60 and 20 size, and flown a 40, and this little jewel is my favorite of all of them. And with its new power package, it can fly off our muddy grass field.
