Electric Old Timers Fact Sheet

 Here is some information about 'Electric Old Timers' a facet of our hobby that the AEFA is actively developing and promoting.  A 'Fact Sheet' covering this material can be accessed here .  

 

 

Old Timers’ come in all shapes and sizes but note the term describes a particular variety of model aircraft, not their pilots.

In essence they are vintage models,

based on designs published or available as kits during the “golden era of model aviation”, the decade of the thirties to the beginning of WWII.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Society of Antique Modelers (SAM), recognized as a world wide authority and advocate of these aircraft, calls models prior to 1939,antique”, and before 1942old timer”. Aircraft up to 1956 are in thenostalgia” category.

 

There are ‘chapters’ of SAM throughout Australia, encouraging all age groups to experience the pleasure of building and flying these character filled models.

 

 

 

 

 

 

 

 

 

Competition among ‘old timer’ flyers has led to the development of rules and regulations that make sure the models look like their vintage counterparts while allowing modern building materials and structural improvements. Replacing ignition or glow motors with electric power is now also an option.

 

 

 

 

‘Old Timer’s were originally free flight models powered by ignition engines or rubber motors. In that era, there were two types of competition, one for a limited motor run, the other for a limited fuel allowance. Current competition rules emulate those concepts.

 

Rules for events currently flown by the AEFA are in the Rules section of this website (here) or downloadable here .  In broad terms they are:

  • Texaco - limited battery (fuel) allowance based on aircraft weight
  • Duration - limited motor runs, battery based on wing area
  • Height Limited - single, limited motor run to a capped ceiling
  • 1/2A Texaco - the same idea as Texaco but aircraft are limited in size and battery options are reduced

 

 

 

 

Starting out with ‘old timers’ might seem a challenge but selecting a good design, and appropriate power package can be very simple if we look at what currently works for others

 

 

 

 

 

 

Here are some tables describing some of the models currently competing in AEFA events.They show that one or two designs dominate and that mid to low price range motors give good results.

Experience in AEFA competitions has also shown that for these first three categories, flyers can be very successful using the same airframe and motor. All that is needed is to change propeller and battery for each category.
