About this Plan
Electra. Radio control sport trainer for 2 or 3 channel radio and .05 electric brushed motor. Discontinued kit from Carl Goldberg.
Quote: "Electra is a state of the art thoroughbred with the temperament of a pussycat. She is based on the proven and popular Gentle Lady (oz2359) sport sailplane redesigned for the higher performance demands of electric flying..."

Supplementary file notes
Kit instructions. Very long and detailed, 32 pages of text and pics. Also, decals sheets and parts identifiction sheet (could possibly be scaled up to draw out the wing ribs?).
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHi Steve, I had at least a couple of flying students with Goldberg Electras. They handled well, but were heavy and climbed poorly with the stock equipment. Six cells were recommended, but that wasn't enough with the direct drive ferrite motor and a floppy nylon prop.A student of mine built one that came out at over 50 ounces with the batteries in it. We put in the old Master Airscrew ferrite motor/gearbox/prop combination, which gave a good climb for sport flying. I only mention these because the fuselage is much wider than it needs to be for modern gear. The old motors are heavy, so you'd still want to use lipos and lighter radio gear. All up weight in the 25 to 35 ounce range is probably best. At over 50 ounces, I found it hard to catch thermals, though I'm sure at 25 it would be easy. That kind of weight (50 ounces), combined with an extended shallow dive, reached an airspeed where pulling up could break the wing. IMHO, this model would be great for a nostalgia trip. Otherwise, it would be better to convert a Gentle Lady using modern gear. The equipment from a Radian ought to be fine for either model, using about a good quality 10X8 prop if competing in ALES to 200 meters. The Airtronics Eclipse was a comparable model that flew fine if built stock from the kit. I think it came out somewhat later, though.

Hello, I built the Elektra 1987/88. It flew very well with 6 -cell NiCd.First flights with standard equipment, then foldingprop . Later I tried 7 and 8 NiCd sub C cells. The best were 7 Sanyo AE-KR 1400- climbing like 8-cells, gliding like 6 cells. Sorry, no pictures. Crashed because of RC-jamming by too little distance antenna-motorcable. Drawback: Space between mainspar and sheeting (Wings).

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
