KeilKraft Senator Global Postal Challenge
June 1, 2009 to June 30, 2010
First kitted by KeilKraft in 1950, the 'Senator' has become recognised as an excellent design that combines simple robust structure with outstanding performance. Very popular in British 'Vintage' events, it also can do well in North American 'Category III' classes Nostalgia Rubber, Moffett and Mulvihill, etc. for which 120 second maximums are a formality and it can be taken well past 180 seconds with little extra effort.
There is no entry fee. The lengthy timescale of this Postal is to permit any modeller an opportunity to participate, no matter where in the world they might be located.
Models are to conform to the standard Senator kit plan; the structure may be amended for the purposes of D/T installation whether tipping stabiliser (LE down), tipping wing or hinged rear fuselage and the undercarriage leg may be removable for storage/carrying purposes. Glazing of the 'cabin' is optional. Any freewheel propellor up to a maximum of 13" diameter may be used and there are no restrictions on rubber motor size/weight.
Individual Scores:- Three flights shall be made to a 120 second maximum. If three Maximums are achieved, then successive flights may be made with the maximum increasing by 60 seconds on each occasion, until the target time is not realised e.g. 120. 120. 120. 180. 240. 211 = Total Score 991 seconds All flights to be pre-nominated to a timekeeper; the initial three should be made on the same day but successive flyoff flights may be made at the flyer's discretion, similarly timed. More than one model may be flown by an entrant but scores for each must stand alone; i.e. a reserve model may not be used to complete a series of flights commenced with another.
A plan may be viewed at http://www.theplanpage.com/st.htm with a download also available (noting that the true span is 32", not 30" as shown on the plan), purchased or obtained from various sources, and 'short kits' are available from at least two vendors; contact me for further information on same or with any questions that you might have.
Team Scores:- If any three flyers wish to have their scores also recorded as part of a team total, please advise a team title when submitting same: I will then collate same as a secondary group score in the name of that team whether they fly together as a club, or as a group of individuals who wish to link together for this purpose. A person may only fly in one specific team, however.
Entries/scores may be forwarded to me at any time, by email or regular post, and I will distribute a final report and result sheet, which will be further publicised as widely as possible. Accompanying anecdotes and photographs would be very welcome and are encouraged. If desired, scores will also be posted to an appropriate event in the WorldWide Postal Contest, details available on request.
An initial award of C$100.00 for 1st.place will be provided; and donations received will be applied to further awards and upgrades. I hope that you will give this event your support and also encourage others to participate.
The 'Senator' is a viceless airplane, easy to build and to fly with very satisfying performance; my only advice is to keep the structure aft of the CG as light as possible to reduce the need for any nose ballast to a minimum.
Happy Flying!
