Langley Model Squadron – Information on a Control Line Club

The photo’s were taken at the Neatherd School Dereham in 2012.  The Langley fliers put on a static and flying display. How many children took an interest in models and model flying ?..None!
They did take a great interest in the Army display of guns and equipment, and a (bad) pop group: what does that tell us ?

The Langley club makes all control line models and occasionally give flying demonstrations at fetes and exhibitions. Our next display will be at the Lomex exhibition in Lowestoft in October 2017.  See here for details.
We have a roped off area and can fly all day. We will give slow combat demonstrations and hold a squirrel race. Area flyers are welcome to come along and fly but must prove BMFA membership and comply with rules regarding wrist straps, hard hats and line pulls.


The idea of squirrel racing is to have as much fun as possible from a simple competition.

The rules are to help teams get safely to the end of each race.

Models Any control line model not designed for speed or racing can compete.  Maximum engine size 3.5cc.

Lines From the centre of the handle to the centre of the model must be 52feet 6inches,+/-3 inches.

Race procedure Heats to consist of 100 laps with one mandatory pit stop. Initially heats will be flown two up. Final to consist of 200 laps with three mandatory pit stops and will be a three up race.

Models must take off from the ground and be pitted on the ground(conditions allowing).

In flight the faster model must pass the slower model by flying higher.

Each team will have a person counting their laps and with a stop watch to time that team. When the circle marshal shouts GO,  watches will be started, and stopped when the required number of laps and pit stops have been completed. If at the end of the race the required number of pit stops have not been performed the lap counter must keep his stop watch running until the stop(s) have been completed plus one lap in the air.

Each team will have the opportunity to fly twice in the heats.

The three teams with the fastest heat times will fly in the final.

A circle will be marked for the pilots. Pilots will not leave the circle until the race is over and all models have landed. Models must be pitted at the marked segments and withdrawn out of the marked flying circle for refuelling and starting.

One or two pit men may be employed by each team but all pit men must wear protective head gear.

Race starts will be as follows:- With pilots in the centre , pit men will be asked by the circle marshal “are you ready for one minute warm up?”. When all teams are ready the one minute will begin for engine warming. At the end of one minute the circle marshal will call “stop engines” and teams will have thirty seconds in which to refuel if necessary and stand back. The last ten seconds will be called out by the circle marshal then “GO”.

Hints :-always prefer to use an engine which will start when hot rather than a poor starter which is faster.

Upright engines tend to flood when refuelling causing bad starting; prevent this by refuelling through the engine feed line, squeezing the feed line when refuelling or turn the engine backwards on to compression and block the carb intake with a finger when refuelling.

Remember there is no restriction on the size or type of propeller to use!
