The recent thread titled 'what did you learn on?' got me thinking about models I built in the early days.

I recall my Dad coming home one day with a very unusual (by the standards of the day) model, I'm wondering if anyone else recalls this model.

It was a free flight model, the flying surfaces were polystyrene foam, in the order of 24 inch span, the fuselage was pod and boom, a wooden dowel boom with a polystyrene pod up from for the motor and battery. It had a mono wheel undercarriage. The motor was a very small 'mabuchi' type direct driving a plastic prop. And then a really unusual feature, if all this wasn't enough, was that the battery was a small 'plastic' pouch which you activated by adding water - possibly salt water.

As I say this would have been mid, possibly late '60s' if my grey matter can be relied on ... I haven't suffered any recent blows to the head, and I haven't made it up ... does this ring any bells with anyone??

No, you're not imagining things it really did exist. Free flight IIRC but the problem was the cost of the one-shot batteries that were very expensive and didn't run the motor for very long. Saw an advert for the model in an old magazine recently.

Can't find the Ripmax model, but came across this from 1963

I had one of those! The abiding memory is the smell of the supplied adhesive. So it was a Sanwa Electra was it? Certainly it looks like the one I had.

Thanks Cuban 8,

The Sanwa 'Electra' is what it was ... isn't it strange to see that concept (small, foam, electric) so many years ago and look at how things have developed today.

Mine did make just a handful of successful flights, the expense of the batteries rings a bell and probably limited its long term use.

Thinking about it, my avatar picture is the E-Flite UMX Radian, which is the ultimate development of the 'Electra' with micro RC gear added to the mix.
