We’ve been running a kit scale duration event at most OMFC competitions for a year or two, and we’ve tried to make the model eligibility as broad as possible so that the maximum number of people can enter.

Unfortunately, this flexibility has come at the cost of complexity so the rules haven’t worked particularly well, and have been difficult to understand for non-scale flyers and CDs. Also, it’s beginning to look as though people are starting to become interested in larger rubber scale models (several construction projects are under way), so we’ve taken this opportunity to split the classes.

We’ve therefore simplified the existing Kit Scale Duration rules and have converted them to an indoor/outdoor postal competition to be run over the Winter/early Spring period between 1st January 2025 and 31 May 2025. We’ll also run a single outdoor event for models built to these rules at the Spring Duration comp on Saturday 31^st May 2025, so if you build a model over Christmas you’ll get a lot of use out of it.

Rules Outline

Models must be built from kits or from plans originally supplied in kits, and there are a limited number of kits that are eligible – essentially, the Keil Kraft Flying Scale series, the Veron Tru-Flite series, the newer VMC Flying Scale series and a few others. You can, however, do more-or-less what you want to the design as long as it’s in character with the original.

Flying rules are slightly unusual and are based on the procedure used in Stuart Darmon’s Classic A1 Postal competition; you start with an easily achievable target duration of 10 seconds. If you manage this, you can make a second flight of max 20 seconds and so on, the max increasing by 10 seconds each time until a max is not achieved or flying cannot continue (e.g. because the model is lost or damaged).

When all the flight times are available, including the last failed max, they are submitted to Chris ( webmaster@oxfordmfc.bmfa.uk ) in the form of an addition, a total and any claimed bonuses that you think you might be entitled to, for example:

   10 + 20 + 28 = 58 points, plus bonus points for Indoor ROGs and 18” span

Chris will then calculate the bonuses and will put the latest scores up on the website. Prizes (Tunnock’s comestibles of various types) will be handed out in early May.

Since we’re flying over the winter period, we’ve taken the unusual step of allowing competition flights to be made indoors; this means that our friends and OMFC members who fly at Trinity and Berinsfield can also take part, and we’re hoping that this might engender a little friendly rivalry. However, if and when the weather improves in the Spring there’s nothing to stop people re-trimming an indoor model at their local recreation ground and recording some outdoor times as well – you never know, you might get lucky with a thermal…
