Diesel fuel can be blended to give easy starting, higher performance. Both diesel and glow fuels come in different blends. In the same way it is worth experimenting to find the best fuel for your engine. The table I have given is a rough guide but experiment yourself with slightly different sizes and makes. Even different makes of the same theoretical site propeller can give noticeable gains or losses in performance. The easiest method is to watch others who are getting a good performance from the same engine and copy them. Using the wrong size prop can have a dreadful effect on performance. Selecting the correct propeller size for a model can be difficult if the makers recom-mendation is not known.

It is also a good idea not to use a full tank for the first flights on short lines. It is easier to cope with a little giddiness than slack lines and an uncontrollable model. When flying a new model I always select a set I think might be a little on the short side. I have built up a collection of sets of control lines over the years and now have all the lengths I need. Both models can be hand-launched and removal of the undercarriage will help avoid the model tripping up on landing. My normal flying field is too rough for taking off and we need to resort to hand launching. If you do not fit these items, the weight might not be necessary.
Both were fitted with an undercarriage and the 60 also has a silencer. The prototypes needed a little weight bolted to the tail skid to get the centre of balance as shown. Adding werght to the tail is much more effective and simple than to the nose, so I always try to err on the nose heavy side.
This will result in a balance point too far forward. Because of the variety of engine sizes and weights which might be used, the nose as shown might be a little long for the heavier set-up. Those who have a izezdy learned to fly should be able to cope with a 1.5cc engine in the 45 and a 2.5 cc engine in the 60. The two sizes cover a wide range of suitable beginners engines and the model is simple to build and easy to fly.įor the raw beginner the 45 should be fitted with a 0.8 cc engine and the 60 with a 1.5cc. Stoneleigh Classic was designed for this task along the classic lines of the best trainers. Not as expensive as li/C, building techniques are relatively simple, most people can get the knack of flying them and finally, the space required is fairly small. Control line trainers fit this bill exactly. To encourage new modellers, especially the younger ones, !feel we need todemon-strata people of their own age group having fun with models which are not too advanced or expensive. It goes into the same category as I put ski jumping and motor racing - enthralling to watch but I could never hope to join in. The skill and perhaps the money required are just too far out of reach. Whilst spectators of the latter will enjoy and admire the show, it always seems to me that they are unlikely to go away thinking that they too could take up the hobby. How does one turn an interested spectator of model aircraft flying into an active aeromodeller? My pet theory is that the popular demonstrations of expensive models very skilfully flown are the exact opposite of what is required. Note the Stoneleigh Classic 45 and Stoneleigh Classic 60 (oz14796) both appeared in the same article in Aeromodeller, April 1983. Planfile includes full building and flying instructions.
