Traditional balsa wood free flight aeroplanes.

Washout is the twist in a wing for stability. I seem to recall spraying the tissue with water and waiting for that to dry which made the tissue taut and then painting / spraying with dope bought from the model shop. Remember doing a few coats of dope to get the tissue tough enough.

I guess it’s all on YouTube now.

Jetex were small jets powered by solid fuel pellets. I built an F86 Sabre to use one but was pretty puny lol.

They were solid fuel rockets rather than jets, and yes were somewhat underwhelming.

Ours crashed so many times, each time any remaining tension of the rubber would conspire to take advantage and crush the area between prop and cockpit. Successive rebuilds saw the area become more and more solid as balsa sheet replaced spars and paper. Sadly a final take off, with the full recommended turns (Well maybe a few extra ones too!) on the rubber, on the North Yorks Moors saw it heel into a descending turn under the effect of a severe gust. Hitting the road, (Instead of nice soft heather) the 75% of the turns remaining managed to rapidly shorten the fuselage to 1/10th of its original length, the port wing was ground to fragments, the Starboard wing parted company, as did the tail, both mostly undamaged. A rebuild this time would have needed a new kit.
