There is a tiny helicopter in front of the car... caught me out too.


Not sure how these little devices work.


Certainly the larger model airplanes and helicopters do have Crystals


They are colour coded and you need to display flags on the aerial if flying near other modelers

so you are not using the same frequency.


You could crash someone else's plane. Some cost many hundreds of pounds...

Yeah.. Back in the 70's people used to meet Sundays on Wanstead Flats..


Some big Models 3'-4' wing span. There was such an incident when someone turned on their transmitter

whilst someone else was flying.


Fortunately the plane was high enough for he owner to gain control after a string of abuse to the idiot

that did not check what flag were showing.


I built a Cessna which a friend finished off and added the electronics... He crashed it on first flight.

despite himself being a experienced micro-light pilot.

crystals...lol they are a thing of the past....now things are done on 2.4ghz and the transmitters have to bind to the receiver making it impossible to interfere with other channels...there are apparently millions of combinations and the transmitter randomly picks a frequency to transmit on.............I cant believe that someone did not see the palm sized heli besides the massive petrol car my dad has......that is only one of the 5 he has,also he has 2 helicopters and a quadcopter....and an aeroplane..i also have an electric rc car...

Cutting edge technology in the 1970s that I was over the moon about getting as a present. It must have kept me amused for ooh minutes.




Todays technology which I would also quite like to play with.




If we can now make toys that learn, will we one day end up with toys that get bored of kids by boxing day and decamp to the house down the road with a bigger garden and more imaginative kids.

    • Covid certainly was a big factor in creating the debt burden however the Govt continues to expand the hole by giving crazy subsidies to suppliers of so-called "low carbon" electricity eg wind turbine farms, solar panels and worst of all - Drax power station. According to the Renewable Energy Foundation, the UK currently spends around £25.8 billion per year on renewable electricity subsidies, covering both direct and indirect schemes. Drax gets just shy of £1 billion a year to use import & burn wood pellets which are produced in a highly energy consumptive process.  Wood pellets used by Drax  are produced through a multi-stage process that converts wood material into dense, energy-rich fuel. The raw material typically comes from, offcuts, and sawmill by-products rather than high-value timber. Logs are first collected from forests across the U.S. South and West Coast, ‘ At pellet plants, the wood is debarked and chipped into small pieces before being dried to reduce moisture content. The drying process often uses waste wood as a heat source to improve efficiency and lower emissions. Once dried, the wood chips are milled into a fine powder, then compressed at high pressure through a die to form small cylindrical pellets, each around 6–8 mm in diameter. The natural lignin in the wood binds the pellets together, eliminating the need for chemical additives. After production, pellets are cooled, screened to remove dust and fines, and stored in large silos. They are then loaded into trucks or railcars and transported across the United States from west to east to dedicated export terminals.. At these terminals, pellets are conveyed into covered storage domes or silos to protect them from moisture, since wet pellets can disintegrate and pose safety risks. From there, bulk carriers transport the pellets across the Atlantic to the United Kingdom. Drax even had to develop specialized port and rail infrastructure to handle pellet imports , including large storage domes at  Immingham and direct rail links to its  power station. It's no wonder wed have the highest energy costs in all of Europe!
    • I found Keith as a recommendation on the East Dulwich forum and I just wanted to add that he did a fantastic job for me. It involved raking out and pointing a first floor wall. He is highly knowledgeable and the finish is great. He was also a pleasure to have around. I highly recommend him.
    • The Tories failed to invest when interest rates were very low.  Irrespective of the current management of the economy, the party that is supposed to know most about the economy, growth and improved standard of living, failed. 
    • I sometimes wonder how deeper the financial £20 billion black hole would be if austerity didn't happen following big financial issues, including the banking crisis, covid and energy crisis (inflation)?
