Set the torque limit on the torque wrench in the normal way. 1. Use a fixed spanner on the prop bolt. 2. Use a transition piece for the torque wrench that goes into the other end of the spanner. 3. Orientate the torque wrench so that its handle is 90 degrees (right angle) to the spanner. 4. Apply force on the torque wrench handle at 90 degrees to the handle, i.e. straight out, i.e. parallel to the fixed spanner. 5. The torque thus created at the "other end of the spanner" transfers along the length of the spanner and onto the prop bolt. As you apply the force/torque, the prop. bolt will turn and you then simply follow with it, i.e. maintain your hand force parallel with the spanner. Re. 2 above: Alternatively, use the "open" end of the spanner on the prop bolt and put a suitably sized bolt (one that the torque wrench will fit onto) through the "star" end of the spanner, with a nut tightened hard on the other side. I have attached (I hope it comes through!) a rough sketch illustrating the principle. Good luck!

I hope all of you on the Last of the Summer Wine and the Canaries trips have a great time - back in the loop towards the end of the month. Cheers, Paddy Do not archive.

Michael In the absence of William Mills and David Joyce I can pass on to you some results of comparisons which they did on the Woodcomp propeller. I know that William has the scimitar shaped blades on an SR 3000. but his engine is the Rotax 912S . ..he also has the control unit by Mark Burton and I know it has a very fast facility to go into "beta" mode (reverse thrust) which I know William makes good use of on his very short landing strip. Unfortunately William and David have just left on " The Last of the Summer Wine Tour" round France so will be about a week before returning and then on or about the 17th Sept. they go on the Canaries Trip for 10 days. However the chart I'm providing will serve as a point of interest until you can get a direct dialogue going with them either between the aforementioned trips or after. Bryan Allsop also has a Woodcomp Propeller but I know it has the straight blades on a 912S as has Davids but David has the Rotax 914.and I think his propeller is the 2000SR. Mark Burton who has developed a superior controller for the Woodcomp may be able to discuss some features with you in their absence. His e-mail address is:- Mark Burton markb@ordern.com But I believe he is also intending to do the Canaries trip as indeed I will be with Bryan Allsop. I attended a conducted tour of the Kremen/Woodcomp factory with the group which went on the first "Six Nations Tour" and I am pleased to confirm that they have a very dedicated and professional team working to exacting standards producing propellers with excellent quality at very advantageous prices. Best regards Bob Harrison. Herewith the document mentioned above....I'm not sure, however, that the tables are for the scimitar 3000SR blades though. The Cedars, Glascoed, Pontypoool, Gwent.

G-HOFC * Both test flights were carried out with identical pay loads (near maximum all up weight) and the fuel used on the first flight was replaced before the second flight was made. * The bugs gathered on the airframe on the first flight were removed before the second flight was made. * Both sets of blades were clean before flight. * The test flights were made between 7,000 and 7,200 feet above sea level where the air was absolutely stable and the wind speed was negligible. * Both flights were carried out in the same area of uncontrolled airspace and with approximately the same headings. * Fuel flow tests at the various indicated airspeeds were carried out at target 5,000 rpm engine speed to allow for the restriction on the SR 2000 reduced coarse pitch limit at high throttle settings. * ** Engine oil temperature was 10 deg C higher for the second takeoff. * QNH was 1027 mb and OAT at ground level was 12 deg C and at 7,000 ft was 1.5deg C * Pilot: William Mills Observer: David Joyce SR 3000/3 SR 2000/3 Takeoff time 09.15 hrs Takeoff time 10.50 hrs Landing time 10.15 hrs Landing time 11.40 hrs Ground run to T/O 183 yards Ground run to T/O ** 242 yards Climb from 1100 to 2100 ft 73 secs Climb from 1100 to 2100 ft ** 71 secs Full power climb rate @ 5,500 rpm and 74 Kts between 3,500 /4,000 ft 1000 ft/min Full power climb rate @ 5,500 rpm and 75 Kts between 4,000 and 4,500 ft 950 ft/min Max airspeed @ 7,000 ft and 5,500 rpm 145 Kts Max airspeed @ 7,000 ft and 5,500 rpm 141 Kts Fuel flow @ max airspeed 22.4 L/hr Fuel flow @ max airspeed 22.7 L/hr Fuel flow @ 100 Kts IAS 11.4 L/hr Fuel flow @ 100 Kts IAS 13.4 L/hr Fuel flow @ 110 Kts IAS 14.1 L/hr Fuel flow @ 110 Kts IAS 14.8 L/hr Fuel flow @ 120 Kts IAS 14.4 L/hr Fuel flow @ 120 Kts IAS 15.3 L/hr Fuel flow @ 125 Kts IAS 16.3 L/hr Fuel flow @ 125 Kts IAS 16.8 L/hr Fuel flow @ 130 Kts IAS 17.4 L/hr Fuel flow @ 130 Kts IAS 18.2 L/hr Conclusion: The SR 3000/3 has a better all-round performance than the SR 2000/3. Normally, the target rpm for high cruise speeds is between 4,500 and 4,700, which would give a slightly better fuel consumption, but for comparison purposes 5,000 rpm was selected to allow for the SR 2000/3 reduced coarse limit. The average fuel flow between the speed range of 100 to 130 Kts was 14.72 L/hr for the SR 3000/3 and 15.70 L/hr for the SR 2000/3, which gives a fuel saving of 6.24%. However, the SR 3000/3 result at 110 Kts appears high when plotted on a graph and it might be accounted for by the aircraft flying at the back of the lift/drag curve causing excessive drag. If this is corrected by interpolation to say 13 L/hr at 110 Kts, the average fuel flow for the SR 3000/3 would be reduced to 14.5 L/hr, which gives a saving of 7.64%. The ground run prior to take-off is 24% shorter with the SR 3000/3. ............................................................... -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of m.grass@comcast.net Sent: 07 September 2006 00:03 Subject: Europa-List: Woodcomp CS curved propeller type Hi all, I am just about ready to order my cs prop. I was set on the Woodcomp. The company came back with the question "curved or straight" blades! My question now is: Did anybody on this list has some comments on the new curved design from Woodcomp? Attached you find pictures from the curved and straight blade design. I could not get good advise so far which would be better for my Tri Gear Europa XS with a 914. Are there any performance data available?
