Old Time Sport Glow—A proposal
The following is a proposal being put forward by Hulan Matthias to create a new event to be called “Old Time Sport Glow.” Most of us have enjoyed flying in the event known as “Old Timer,” models designed and kited before and through 1950. One of the most challenging parts of this event is the rule limiting engines in this category to Spark Ignition or diesels on SAM approval lists. It is the intent of this new event to allow any “old timer” eligible plane to be flown with any glow plug engine with the following limitation. Large engines, .11and up must be limited to 12,000 RPM and small engines, .10 and down will be limited to 14,000 RPM. Any type of fuel delivery system (pressure, pacifiers or suction) will be allowed. Both Pylon and Cabin old timers can be flown in this event. Please Note: Use no more then 10% nitro fuel.
There will be two categories in this event: Small Old Timers with engines at .10 and below and large old timers with engines .11 and up. For instance, Hulan Matthias and Phil Ronney have Champions (designed and kitted in 1949) with K&B Greenhead .09’s, these planes would be allowed 14,000 RPM engine runs. Phil also has a swayback up scaled to over 750 sq. in. originally kitted in 1947, with a K&B Stallion .35. It would be eligible in the large category. It would have to run at less than 12,000 RPM has to avoid penalties.
Engine runs will be 20 seconds hand launch with three minute maxes for the first three flights. Fly-offs will be as follows. The first fly-off flight will be 15 seconds. The second fly-off flight will be 10 seconds and all succeeding fly-off flights will be 10 seconds.
Builder may enlarge or reduce size of model but must not change the original profile surface outline. Narrowing the width of fuselage for safety and ease of handling and starting is allowed.
The contest director may designate an individual to check RPM’s with a tachometer or if he chooses or he may simply make each contestant responsible for measuring his own engine RPM. Each contestant would then be required to run the engine at maximum needle valve settings while the using a tachometer to check RPM before flying in the event. No change can then be made in fuel type or prop size without re-taching.
For engines that exceed the 12,000 or 14,000 RPM rule a penalty of 2 seconds for every 1000, rpm over the allowed amount will be imposed. For instance, a large model might tach at 12,500 and would therefore be required to limit the engine run to less than eighteen seconds. A large model that tached at 14,000 would be given a penalty of 4 seconds requiring the participant to limit the engine run to sixteen seconds.
Note: Any glow plug engine, nostalgia or modern can be used in this event. The limiting factor is of course, RPM. The use of glow plug engines does not preclude the use of either Spark ignition or Diesels so contestants who feel comfortable with older Old Timer engines can use them. Nevertheless, the RPM rules still apply. No electric engines will be allowed.
Hulan encourages interested parties to fly in this new event when it is offered at the monthly Scamps contest at Perris and by all means contact him with suggestions for modifications to the rules.
Thanks for your interest
