Comp Rules


	WESSEX ELECTRIC THERMAL COMPETITIONS 10.30am start. Briefing at 10.15 am. Two classes will run concurrently, for both Open class and Restricted Class gliders. Both classes will launch separately from the other. General Rules (for both classes) Frequency control. Peg on aerial system. Return peg to board when not flying. Bring spare frequencies. Each pilot to fly 1 flight against each other in their Class. Both (or more) competitors launch at the same time. Timing starts at launch. Last one down wins. Motor run only at the launch of each flight. (Note: at any time motor mat be used for safety, STOP timing when the motor is switched on.) A time keeper is required for each round to (a) collect the scorecard (b) record results (c) return the completed scorecard to the Scorekeeper. No telemetry assistance allowed. Pilots to be prepared to fly promptly with next available competitor(s), once the previous round is decided. Pilots to compete in 75% of flights or scores discounted, any uncompleted flights to be a walkover. Overall ties to be decided by unlimited fly-offs. A prize will be awarded for each class winner. (There may be an entry fee at some events.) Contest Directors’ decisions will be final. Open Class Rules. Contest Director Nigel Bennett. 1. Any spec of electric powered soaring glider, electric motor and power pack is eligible. 2. Height of powered climb will be limited, ideally with all models incorporating an altitude limiter. In the short term, those competitors not using altitude limiters are asked to ensure their models comply with the 200w/kg rule, either by adding weight if needed or by using a smaller diameter, or reduced pitch propeller. 3. Those competitors using limiters will be allowed a maximum powered climb of 200m, or 35 secs, which ever is reached the sooner. 4. Those competitors not using limiters will have a maximum powered climb time of 30 secs. 5. Timing will start from launch and there is a flight maximum time of 10 minutes, finishing either when the model lands or when the motor is restarted to avoid an outlanding. Only one motor run allowed per timed flight. 6. Spot landing points will be awarded as long as the model lands less than 10mins and 10 secs after launch. . There will be two 5m long tapes also marked at 2m. 1/2 pt will be scored if the nose of the model is within the 5m radius, and 1 pt if within the 2m radius. The competition will be flown as a Round Robin, where each pilot flies against every other pilot in turn. Points scored will be 4 for a win, 2 for a draw, and either 1/2 or 1 point for spot landing as described above. The loser gets no points other than spot landing points. In the case of a draw (both with Max’s or both with identical times) the 4 points are shared, ie 2 each. 600RES Restricted Class. Contest Director Chris Hague Any model. Maximum number of servos 3. (Rudder, elevator & optional top wing mounted barn door type, spoiler/air brake only.) One direct drive standard ferrite 600(max.) motor to be used. Maximum retail price of motor £10. (Multiplex 600 7.2v or Graupner 600 7.2v motor recommended.) Maximum 7 cell Nicad or Nickel Metal Hydride pack only to be used, pack may be charged/changed between flights. (NiMH 2200 x 7 cells recommended.) Wing to remain fixed both cordwise and spanwise (except for optional top wing mounted, barn door type, spoiler/air brake only.). No limit to the number of eligible models to be used. 45 second motor run, only at the beginning of the flight. (1 minute motor run for standard, unmodified, ARTF, plura fuselage types. e.g. Bluebird 100, Easy Pigeon etc.) Score 4 points for a win, 2 points for a draw. (If more than 2 flying against each other, score 4 points for each pilot defeated). Max flight time 15 minutes. If both (or more) pilots draw or are still flying at 15 minutes then the points are shared equally. Chris Hague/Nigel Bennett Ref: WES02
				*2009 WESSEX TOMBOY* COMPETITION RULES The event will usually be run with 2x qualifying flights of 4 minutes minimum, with a fly-off to decide the overall placings. Each competitor to show proof of BMFA Inurance. Each competitor to supply a timekeeper and stopwatch. (Willing timekeepers often available! See the Contest Director if necessary.) Hand launch allowed by either competitor or an assistant. Fly-off to consist of a max of 8 pilots, if necessary heats and semi-finals of 8 max pilots to take place first. For the Fly-off, 90 seconds will be allowed to start the engine followed by a 10 seconds warning to launch. Launching must then take place. Zero score if launching is late. Landing to be in the designated area or zero score. If more than one competition takes place overall positions will be calculated for each round as follows; Winner 10 points; 2^nd 9; 3^rd 8; 4^th 7; 5^th 6; 6^th 5; 7^th 4; 8^th 3; all others in the fly-off achieving a score of 2 points. Entrants making a flight but not making the fly-off to receive 1 point. Overall tie break to be highest placings. Models not within the rules to be allowed to compete at the Contest Directors, discretion. The CD may request an examination of any competitors engine to check legality. Infringements will involve a time penalty. (e.g. Undersize wheels, 1 minute to be deducted from the fly-off time) You have been warned!!!! Pilots who have registered a unique frequency with the Contest Directors’ will be given total priority on that frequency. For various reasons (e.g. safety) these rules may need to be adjusted on the day by the Contest Director. Return timesheets + entry fee (if required, say no more than £2 as funding towards prizes), to the Contest Director, whose decisions are final. Construction of the model rules are as follows: WESSEX TOMBOY Vic Smeed Tomboy with 36” span and small tailplane as per plan. Depending on the plan you use there are slight variations in size of tail plane therefore we have adopted a maximum span of 423mm x 110mm chord including elevator. (NOTE: One elevator trim tab is allowed, maximum size 2” x 0.5”) Wing to use bottom spar only. Free choice of spar material. Extra strengthening allowed to the airframe. Any covering material allowed. NOTE: National Tomboy 3 events do not currently allow any plastic shiny heatshrink types of covering to be used. Pair 2“ (50mm) min. diameter x 15mm min. width balloon style wheels to be fitted. 2 or 3 servos to be used for rudder, elevator and optional motor control only. Engine to be standard unmodified plain bearing Mills .75 either original or other replica. Or beam mounted MP Jet 040 Classic of 0.6cc. NOTE: MP Jet not allowed in National Tomboy 3 events. Integral fitted fuel tank of 3cc maximum capacity to be used. (access required to check capacity) MP Jet 040 if using after market 3cc tank to have 10 second launch delay, no fuel to be added during that time. No deduction if using standard MP Jet tank. Standard, or replica, carburettor with nominal 1/8” bore only, no tuning allowed. Propeller to be standard grey Graupner 7 x 5 only. No folding props allowed. WESSEX TOMBOY Senior Vic Smeed Tomboy scaled up by 1/3^rd to 48” span. (NOTE: One elevator trim tab is allowed, maximum size 2” x 0.5”) Wing to use bottom spar only. Free choice of spar material. Extra strengthening allowed. Any covering material allowed. NOTE: National Tomboy Senior specify textured covering to be used. Pair 2.5“ minimum diameter x 20mm minimum width balloon style wheels to be fitted. 2 or 3 servos to be used for rudder, elevator and optional motor control only. Engine to be standard unmodified plain bearing** Mills 1.3 either original or replica. Integral fitted fuel tank of 6cc maximum capacity to be used. (access required to check capacity) Note: Irvine tank is larger, and an aluminium insert is required to reduce the capacity to 6cc. (Contact James Parry if further information is required.) Standard, or replica, carburettor with nominal 1/8” bore only, no tuning allowed. Propeller to be standard grey Graupner 9 x 4 only. No folding props allowed. Helpful notes: Purely to encourage and make it easier for new participants these rules differ slightly from those followed by the National Tomboy 3 and Tomboy Senior competitions therefore if you wish to enter the national competition please verify those rules and your model beforehand. As there are often 16 or so competitors at the National events we at Wessex league intend to follow their frequency request system whereby competitors reserve their 35 MHz frequency for the year so that on the day of an event there are no clashes. Please phone James Parry or email with your frequency. It will be on a first come first served basis. No 27 MHz permitted. Partial Tomboy kits are available from the Old School Model Aeroplane Factory, Belair etc. A variety of Mills engines are often available on eBay. At most Vintage meetings various engines, props and bits are often for sale. Please note only plain bearing engines are allowed.

3, Any spec of soaring glider is eligible for 2m class, as long as the Max wingspan is 2m, Launch by Bungee.

4, Launch by Bungee; Bungees to be of similar construction ie; rubber to be of similar length and type.

5, Timing will start from launch . Maximum time on line to be approx 10 secs Winch, 20secs Bungee (to prevent Kiting) Maximum flight time of 10 minutes, ending when the model lands.

6, Spot landing points will be awarded as long as the model lands less than 10 mins and 10 secs after being launched. There will be two 5m long tapes also marked at 2m. 1/2 pt will be scored if the nose of the model is within the 5m radius, and 1 pt if within the 2m radius.

7, The competition will be flown as a Round Robin, launch in pairs only, where each pilot flies against every other pilot in turn. Points scored will be 4 for a win, 2 for a draw, and either 1/2 or 1 point for a spot landing as described above. The loser gets no points other than spot landing points.

In the case of a draw (both with Max’s or both with identical times) the 4 points are shared, ie 2 each.

8, A timekeeper is required for each round to (a) collect the scorecard (b) record results (c) return the completed scorecard to the Scorekeeper

9, These Rules are subject to change, due to experience and local conditions.

10, All planes must land in the takeoff field to score.

11, The overall idea is to have a simple fun event.

12. The competitions will be held at the Wessex Soaring Association site at Chalbury Farm about 5 miles north of Wimborne. There will be a charge of £3.00 for all non WSA members taking part.

13 A peg on Aerial system is used at Chalbury Farm, and there are some no fly zones which will be explained at the pilot briefings, which are to be at 10. 30 am .

14. Electric soaring is strictly forbidden at the Chalbury site, however electric thermal soarers can winch/bungee launched in these competitions provided that the propeller blades are removed and the motor is disconnected BEFORE the model arrives at the flying site.
