Though this has been discontinued there are still kits around its a gentle lady converted for electric. In fact I think it comes with an old brushed motor which means lots of room for a brushless replacement. http://www.carlgoldbergproducts.com/.../gbga0040.html The electrics are not hard to figure out most motor manufacturers give you the prop sizes and battery configurations. The extra weight does not effect the performance as much as you would think. A little in calm air but the little extra weight gives better penetration in brisker winds.

This will out perform any of the Goldberg Lady’s in all aspects and is much better built. It’s available still today. Mine is at least 10 years old and still wins many club glider competitions. It has rudder, elevator and pop up spoilers as well as the electric motor. It’s only 85 dollars and is one of the easiest gliders I have ever built. At the bottom of the web page it gives some tested combinations motor, esc and battery combos. http://www.djaerotech.com/dj_product/chrysalis2m-e.html

Being able to fly and restart the motor when low you will get several climbs to altitude with one charge something you cannot do with your nitro motor. Another saving grace with electrics is the ability to keep the model out of the rough by being able to throttle up the motor to get you back to the field or make a go around if you need to. This can save a ton of repair work and help keep the model light and straight for many years.
