BMFA F5J League Event - Sunday 20th September – Leigh Park Farm, Tonbridge

Tonbridge club are hosting their first F5J event at Leigh Park Farm, Nr Tonbridge, Kent on Sunday 20th September. This is a new venue for a F5J BMFA league event at what is probably the best RC Glider Flying field in the South. We will be running a relaxed and fun competition for both existing competition flyers and new pilots alike.
 
YOU DO NOT HAVE TO BE A BMFA MEMBER TO ENTER BUT MUST BE ABLE TO PROOVE YOU HAVE INSURANCE

Directions to the field can be found here:
https://www.google.co.uk/maps/place/Leigh+Park+Farm/@51.2091254,0.19327,17z/data=!3m1!4b1!4m2!3m1!1s0x47df4fda3f5fd36d:0xfd76d04136677dd9?hl=en

The competition will be run to F5J rules with UK variations as published by the BMFA. Copy of the full rules can be found here:
https://bmfa.org/DesktopModules/Bring2mind/DMX/Download.aspx?Command=Core_Download&EntryId=1060&language=en-GB&PortalId=0&TabId=219
 
The main points for BMFA F5J comps are:
- Either Open or 2m may be flown, not both.
- Motor restart may be used (results in a zero flight score), and therefore you need only use your eSoaring switch BUT you must reset the (200m) height limit to 300m this can often be done easily by using a reader, otherwise use a computer.
- As in eSoaring, you must provide a reader, so that your timekeeper can check your launch height immediately after landing.
- Minimum of 4 rounds to be flown.
- CD will announce whether or not a Fly-Off will be flown before the start.
- Book in from 9am. First flight’s at 10am

Entry fee £10.00 (BMFA requirement) payable on the day.
Proof of BMFA membership (card is sufficient) required

Closing date for entries is 6.00pm Friday 18th September.

In the event that there is any doubt as to whether the event will be run due to forecasted inclement weather, a final decision will be posted on BARCS, Esoaring and Flyquiet websites by no later than 4pm on Saturday 19th September.

Here's hoping the weather gods look kindly upon us on the day! Colin.

Tonbridge F5J 20 September 2015-09-25

 What an entry, what a day!

 It’s not that often at this time of year that we get perfect RC soaring weather but that turned out to be the case for the inaugural Tonbridge BMFA F5J competition. When we arrived at the field around 8.00am it was shrouded in dense fog with cows spread all over the massive field which TRFC flyers are lucky enough to have as their club field. It wasn’t too long though before the farmer appeared on her quad bike along with her dogs to round up the cows and usher them off the field leaving us with a clear flying field. The fog however was somewhat more reluctant to cooperate! Eventually it did lift leaving us to get started around 10:30 am.

 Once everyone had got used to the computerised automated comp running system (See end of report for details) it was amazing how 99% of pilots managed to be on time at their spots ready to fly their slot. Knowing that not being ready and frantically waving their hands on the flight line to stop the slot starting would be fruitless probably had a lot to do with this!

Throughout the day lift and sink was to be found in equal measures with some slots being relatively easy to fly out whilst many others proved to be far more difficult. Unusually, we witnessed some low launch heights for an UK F5J comp, particularly from Peter Mitchell who flew exceptionally well throughout the day with his Pike. The average launch height during the day was 150-190 meters which seems to be the norm for UK F5J events. One pilot though did manage to record a launch height of over 270 meters! There were only a few instances of non recorded launch heights resulting in a zero score. Motor re-starts were also very few and far between, less than three if memory serves me well.

At the end of a great days soaring it was Tonbridge Club’s Keith Fisher who triumphed with a perfect score of 4000. Keith’s dropped score was a 980.99 which meant had there been no dropped score he would still have won by a big margin. As his score indicates Keith flew superbly throughout the day and deserved to take the top spot. Runner up was Peter Mitchell who also flew extremely consistently to take a well deserved runners-up position with Brian Austin flying a home built model coming 3rd. The full results are printed below for those interested in the overall placings.

On a personal note, it was very pleasing to see so many new and old faces competing at an F5J event. We are extremely lucky in the SE corner to have a lot of electric RC soaring pilots and had we not had a few late pullout’s we would have had over 30 flyers competing. Even at 24 pilots I believe that this was probably the largest domestic UK F5J entry to date.

 Many pilots expressed that they had thoroughly enjoyed the competition with friendly like minded individuals and that they had realised that F5J wasn’t the cut-throat, win at any cost competition that it’s often portrayed as. Thank you to each and every pilot that supported this competition, it made all the work worthwhile. I hope the attached pics give a flavour of what a great days soaring it was.

 Lastly, many thanks to Kevin Beale and Graham Wicks for their help in organising/running the competition.

Automated computer scoring and comp running system

Several people expressed an interest in our home made wireless PA and computer controlled comp running system so here are a few details about it.

One of the reasons that its often difficult to get people to run competitions is the sheer amount of heavy/bulky gear that has to be stored/transported/set-up at the field. This becomes a bigger problem once the initial enthusiasm of the few who commit to run competitions has faded. The bulkiest items by far are the PA system/wiring etc.

Graham, Kevin & I decided to investigate and find a way of reducing all the PA gear down to a compact and easy to use/set-up self contained system and couple this to the wonderful Gliderscore software program (http://www.gliderscore.com). For those that don’t know, Gliderscore is the defacto world-wide standard for fully automated computerised glider competition running/ scoring/reporting. Its a free software program (donations greatly appreciated though!) written by Gerry Carter from Australia that provides a solution to completely automate the running of any RC Gliding competition including automatically calling up pilots by name for every slot, handling all timing call outs as well as matrixing/scoring/reports etc.

Graham had picked up from the web an interesting idea that used Aluminium Tx cases as self contained PA Speaker boom box’s which were powered using cheap EBay 12v amplifiers and 12v/7aH sealed alarm batteries to power the box(s) all day. Two high power car stereo speakers per box fitted nicely leaving plenty of room for the small amp, battery and fly leads to connect to the wireless system. Two of these box’s were quickly built by Graham. They are small, light and easy to store/transport. It’s just like carrying your Tx case! We were initially concerned that the box’s might not be loud enough to be heard clearly on the flight-line but tests showed categorically this would not be the case for anyone with reasonable hearing.

Next came the issue of how to link these box’s to the instantly erectable control centre, aka Grahams new van. A little research showed that we might be able to use a 5.8Ghz wireless AV system off Ebay that is normally used for sending/receiving AV signals in halls/gyms and homes. Much to our amazement this turned out to work very well with a LOS range of up to 100metres being possible with clearly spoken audio. Three wireless channels are available from these cheap units (Around £35) which meant we could connect two Boom/PA box’s, and use the third for flight line PA announcements, all sent from Grahams van. The AV Sender/Receiver’s are powered by a 4 cell 2200mah NiMh pack running through a 5v BEC which lasts all day.

Tests showed that the expected interference from people walking in front of the wireless units was not in practice an issue. The AV sender is connected to the laptop running Gliderscore and then placed on top of Grahams raised rear door.The AV receiver is placed in the middle of the Boom/PA box’s (which are approx 20-25 meters apart) The PA Box’s are placed parallel to and upwind to the flight line. They are raised above ground level by placing them on plastic buckets (very high tech!). The back shelf of Grahams van is used to put the laptop on and the other ancillary bits. The rear internal van shelf also provides great shading to see the laptop screen easily in sunlight.

Total time to set-up is vastly reduced compared to wired PA systems with the added bonus that there are no wires to trip over and pull out etc. More important is the fact that transporting all the gear is now not a burden/issue. All the gear required to run the entire system at the van end comes from one single 12v car battery which lasts all day. Other than this single 12v car battery, all the gear at the car end including the laptop fits into a Sainsburys ForLife carrier bag! Compact or what! The system to date has exceeded all our expectations and will continue to be improved.

One of the areas we are now addressing is that unlike F3J where all the competitors stay out on the flight line during the competition and can therefore easily hear PA announcements, F5J competitors have a tendency to stay with their cars which are often located some distance away from the flight line for safety reasons and charging etc. This can make it difficult for pilots to hear announcements from the flightline PA box’s. To resolve this issue, we intend in future to run a separate boom box/PA that will be pointed towards the cars so that its far easier for pilots in the pits to hear all announcements. We are also looking into the possibility of adding a third flight line PA Boom Box which would allow us to accommodate more than the current max of 6 pilots per slot. We could achieve this now if we reduced the 15 meter spot spacing to 13mtr (which is still more than we have seen at other F5J comps) but prefer if possible to keep the 15metres spacing.
