View Full Version : Electrifying already built Gentle Lady: help!

09-05-2006, 06:11 PM
Have a Gentle Lady that has been flown as a glider that I want to convert to electric power. I'd appreciate suggestions on motors and batteries to use. I'm not looking for max performance; just a relaxing flier.

Here's a link to a web page I bookmarked a while back for if/when I decide to electrify my GL:


I hope this helps.

tush they make an easy conversion. I cut the nose off of one and put a geared endoplasma motor on it. With the brushless and lipo options that you have today, it would make an easy conversion for you.

The Goldberg Electra is basically a Gentle Lady with a motor. You could use the power setup that is used in that plane.

Hi All,

This is one of my winter projects as well. I have had good success flying a GL with an .049 glow many moons ago so I was thinking for the electric conversion I would use an E-Flight 400 or 450 outrunner and folding 9X6-ish CAM prop with a 3S 1300-2000mA pack depending on the duration time I would need and weight. I'm not very worried about the balance as it balances just fine now and I'll be eliminating the 4 AA NiCad receiver pack and replacing it with the motor (which is further away from the CG) and a Lipo pack. In the outside chance that it ends up a bit tail heavy, I'll just use a larger batt pack. Should be great fun and a great addition to my Bird of Time...

Sounds good! I hope to get to it this winter.

Franny, the 450 would be way too much power for a 2m glider. I put a 400 on a scratch-built (from plans) Astroflite 2m and it would climb to a spec in about a minute!! 3s1p 2100 lipo never ran down in flight, usually half-discharged or less.
