Spit fire had a 49cc strimmer engine in it two stroke acctually flew very well .. sold it because I was affrade of crashing it

I forgot about my steam days too. I used to build 00 railway lay outs then I semi built a live steam 0-6-0 saddle tanker .. I bought it off a chap who never finished the kit ..I finished it off and joined the steam club .. only problem was not enough track space I needed a bigger garden +++ it drove nice with the tender housing a water tank as well as the seat to sit on and drive it.

Spit fire was the same semi built unfinished project. 1/3rd scale took me 3 months to finish it always fancied jet engines I looked at a helicopter once that was a turbine one just expencive if they go pete tong

That music box is very nice, and ingenious too....

14ft Spitfire...wow.Would like to have that.One of my favorite planes.What engine did it had? Reduction from Mick Reeves? :)

Agreed the big ones are less twitchy, but as Guy says its the fear of crashing them that put me off. I waited until cheap electric motors and light rc gear became available. The small foam electric jets can now be bought for around $70, and airframe replacement as low as $25. When I was a kid I had a rubber band powered balsa and tissue plane, that didn't last long :)

Its amazing how far technology has come, now you can buy a tiny plane weighing 38g with all the rc gear in there, motor, battery, elevator, rudder, some even have ailerons too. They fly very well for such small planes.

Oh! and batteries, that was the main thing! the batteries. When I was a kid everyone flew petrol engines, because NiMh batteries (dont even think about lead-acid) were too heavy and could not provide much current. Now when Lithium Polymer batteries appeared it was a game changer. Now I can draw 25A reliably from a 850mah capacity battery, its almost hard to believe. Most household appliances are limited to 13A!

sorry just one more video, if you fancy jet engine sound without the huge price tag, check out the 10 blade, 11 blade, 12 blade electric fans, they sound amazing. This is what I'm getting next. :D
