That was a quick response br. should there have been some photos?

At this precise moment this computer is really playing me up – taken ages to open this page so I'm going to say thanks for being the first to post and will be back later (over a minute to get the smilies to open!)

As a lad, I used to fly this speed aeroplane at the Rand Model Aeroplane Club. It was powered by a 6.5 cc K&B Torpedo engine. Great fun, even if it go home as "pieces of eighth" at times…

As an aside, some years later, I was having dinner with a friend. Conversation eventually got round to aero modelling, at which stage his son gave me a sideways look and asked whether I used to fly a 40 speed 'plane at RMAC. I did. To which he replied that he and his friends used to hide behind the car when I flew!

Are you in SA DrDave?? I used to fly at RMAC too – many years ago. Actually learnt to fly there..If you are in SA, do you know Neil Dawson – Good pilot that Chap!

I started model building with a KK Luscombe Silvaire, rubber powered kit, typical for the range of kits was 1/16" sq stringers to give the fuselage shape, tissue covered and doped. I know now I spoilt the performance of the model by adding red paint all over, it did fly but only very short duration.
Next was a KK Dolphin, a towline glider which gave decent performance and kept me out of mischief for a good period of time.
Xmas gift was an ED Hornet, 1.5cc diesel, this was fitted into a newly built KK Champ? profile fuz and single sheet solid wing control line trainer, always hand launched by a pal over long grass to help reduce the risk of damage for the early training flights.
I build and flew a good number of c/l models including a Midge speed model and after swapping a Diana air rifle for an ETA29 I built the KK Pacer, class B team racer.
The last c/l model was a Mercury Crusader stunt model powered by a new OS 35 glow engine, had a lot of fun with that model on 50ft lines.

Then came my change to Radio Control, that's another much longer story for another time.

When I was eleven years old (1956) I was still very much Meccano orientated.

We had moved from one end of town to the other which meant a change of school. Visiting a school friend from previous days he had discovered the joys of the Keil Kraft 'Flying Scale Series' and was building an Auster. This was my very first sight of a model aircraft and I was totally smitten that you could actually do such a thing.

I returned home fired with enthusiasm. Money was tight but I did manage to save the three shillings and ninepence (just under 20p) and bought my first model kit the KK 'Flying' scale Sopwith Camel. Flying is in inverted commas as obviously, though I did manage to build it without help the last thing it could do was fly. Maybe the lack of dope (more expense) was the reason but it did look (well to my eye that is) like a Sopwith Camel. Undaunted by this disappointment it was followed by the Mustang and Lysander neither of which flew anything more than a hop either so advice was sought from the model shop proprietor, one Stan Gooderham. Try this he said – a Veron Goblin, a lovely little model with a diamond fuselage but at the limit of price range. Skills were improving and I even had some dope by now an lo and behold it actually flew and flew well. It would even ROG but with limited flight pattern but it FLEW.

I have been hooked on building and flying them off and on ever since and the hobby has followed me life long.

'Engines' would come along about eighteen months later but that's another tale.

Keith I have a Juggernaut pulse jet complete with a battered box, it’s never been run but time has not been kind to the tail pipe.

Ramon,

I was an apprentice Patternmaker at Drummond Bros. They were a very forward looking company and had started a group bonus scheme that everyone got a share of just prior to the annual holiday in July. My bonus was £10.00. The Juggernaut was £6 10 shillings,so I splashed out. My father did not approve. He thought I should spend it buying the tools I needed.

Keith

Wow Keith that was some bonus in 1948.

My first job as an apprentice welder on the shipyard in 1960 saw the princely sum of £2 11 shillings a week rising to £2 14 shillings shortly after due to a boiler maker apprentices 'strike' in the north of England. – I didn't earn much more that that until in went in the army.

I remember my mother going mental when I spent most of some birthday money on the Hobbies lever tensioning fretsaw. Cut out a few ply formers with that and still have it though never use it – hangs on a nail in the loft!

I bought a pulse jet at Henry J's whilst in the army – never did use it and have no idea where it went – probably in exchange for another engine. Engines have, to the main part been, very transient things and I've had many over the years – somehow they seem 'attracted to me' as I certainly don't collect them. When I sold up a couple of years ago I kept back five or six – since returning to flying C/L they are already accumulating steadily way beyond that number.

Old School,,

Now that you have given yourself the idea,you must carry it out. Think of the noise it will make! Check the leaf valves are still OK first.though.

Keith

Bob,

Did the Brauner jet use a commercial available leaf valve?

I have a friend who had/has several jets and spares – I could ask him for you if he can help if you know exactly what you require.

Tug

Pulse Jet Leaf valve – Hi Tug, I made the original leaf valve (petal Valve) out of 0.015" shim stock having borrowed a pair of case hardened steel plates that had been made to the same dimensions as the leaves. The shim stock was clamped between the 2 plates and then filed to shape. The final valve was then surface ground to remove any burrs and bring the thickness down to 0.010". Alas, I don't have the plates now or access to a surface grinder.

Bob

Hi Rob,t

I had exactly the same experience back in the 1950s. My dad gave me an ED Racer engine for my birthday. I built a balsa control line model for it and first (and last) time out it was so fast I destroyed it in half a lap!
