For faster USA shipping options, give us a call at 520-722-0607. The DA-85 combines the low weight and the affordable price of a single-cylinder-engine with the power usually only 100cc engines have. The perfect choice for your 35%aerobatic airplane. A great choice for your large scale warbirds too. The minimal crankcase volume and the timing with the four reed valves produces a very high power output. The high torque with reduced side thrust, this reduces the friction and wear as well as increasing the power. An aluminium throttle arm is fitted to the carburettor throttle shaft. The world wide DA service and support is unique. The DA-85 is certainly the best choice for your 1:3 3D aerobatics. What if small thrust changes are required by an additional degree or two when trimming the plane out with a Solid Mount (No washers can be used like with stand-offs) ??? Stand-offs are used on alot of big gas engines with no problems. PICTURES are greatly appreciated Thanks for any help !!!!Their Extra 260 does?Im looking for a spare to use on my scratch built plane if you find one you dont need.My build is the 75cc Yak QB, no mount or template and AW does not have any spares for sale at this time. The Extra is the only kit modded for the DA 85 for now. Gotta be fabricated. Just looking for suggestions.Thats a good enough reason to do it as they say in the DA85 manual. There is a template on the back page. You can copy that and paste it onto a peice of 6mm ply. Drill it and cut it as shown. The advantage is to now mount your engine to a perfectly flat surface. Now by spacing your stand offs as far apart as possible you reduce the torque, or twisting effect on those standoffs. It all makes sense when you see it done. I for one will mount all my engines in future this way. The reason being you only ever need one set of holes in the firewall. Later on if you want to change engines or have need to set more off thrust etc you can do so by making a new motor mount plate.http://www.profikaneten.hu/kepek/dell-latitude-d410-repair-manual.xml

Your firewall does not end up looking like swiss cheese.I can make thrust line adjustments by adding washers to the front on the standoff's and the motor will still be bolted to a flat surface. Is it ply with a carbon overlay or is if CF plate. Looks bloody killer mate.I too would like to know what you used to fabricate the plate with. Thanks for the reponse and Pic's.No carbon for me, but I will paint it when it's finished.The engine essentially has a mounting ring. The entire ring needs to be supported or the torque of the engine, along with gyroscopic loads, can twist the engine case - a bad thing. The biggest reason why you shouldn't use standoffs on this engine is because DA says not to - seems simple to me.Mounting it on a plate, then putting standoffs on that plate is simple, and really no different than using regular old standoffs. It's the way my 3w106 came from the factory, worked very well.All rights reserved. The engineers at DLE have thought of everything. Vibration — a real concern for many single cylinder engines — is checked by a vibration-dampening engine mount. Plus, an exhaust extension lets the engine fit in more planes without cowl modifications. This extension will flex or pop off during a hard landing, helping to protect the engine.

For the elephant, see Osama bin Laden (elephant). For other uses, see Bin Laden (disambiguation) and Osama (disambiguation). He subsequently became the subject of a decade-long international manhunt.The spellings with o and e come from a Persian -influenced pronunciation also used in Afghanistan, where bin Laden spent many years.Mohammed recommended Hamida to Mohammed al-Attas, an associate.Bin Laden's other known wives were Khadijah Sharif (married 1983, divorced 1990s); Khairiah Sabar (married 1985); Siham Sabar (married 1987); and Amal al-Sadah (married 2000). He wore a plain white keffiyeh.In November 2001, he maintained that the revenge killing of Americans was justified because he claimed that Islamic law allows believers to attack invaders even when the enemy uses human shields.

Bin Laden established camps inside Khyber Pakhtunkhwa in Pakistan and trained volunteers from across the Muslim world to fight against the Soviet-backed regime, the Democratic Republic of Afghanistan.While Azzam acted as support for Afghan fighters, bin Laden wanted a more military role.With Iraqi forces on the Saudi border, Saddam's appeal to pan-Arabism was potentially inciting internal dissent. Bin Laden met with King Fahd, and Saudi Defense Minister Sultan, telling them not to depend on non-Muslim assistance from the United States and others and offering to help defend Saudi Arabia with his Arab legion.They discovered copious evidence of terrorist plots, including plans to blow up New York City skyscrapers.Many of his labourers were the same fighters who had been his comrades in the war against the Soviet Union.In 1995 the EIJ attempted to assassinate the Egyptian President Hosni Mubarak. The attempt failed, and Sudan expelled the EIJ.According to Sudan officials, however, this stance became obsolete as the Islamist political leader Hassan al-Turabi lost influence in their country. The Sudanese wanted to engage with the U.S. but American officials refused to meet with them even after they had expelled bin Laden.The Saudis, however, did not want Bin Laden, giving as their reason their revocation of his citizenship. Sudan's minister of defense, Fatih Erwa, has claimed that Sudan offered to hand Bin Laden over to the United States. The Commission has found no credible evidence that this was so. Ambassador Carney had instructions only to push the Sudanese to expel Bin Laden.In secret meetings with Saudi officials, Sudan offered to expel Bin Laden to Saudi Arabia and asked the Saudis to pardon him. U.S. officials became aware of these secret discussions, certainly by March. Saudi officials apparently wanted Bin Laden expelled from Sudan. They had already revoked his citizenship, however, and would not tolerate his presence in their country.

Also Bin Laden may have no longer felt safe in Sudan, where he had already escaped at least one assassination attempt that he believed to have been the work of the Egyptian or Saudi regimes, and paid for by the CIA. Bush cited the necessity of dealing with the remnants of Saddam's regime (which Bush had chosen not to destroy).The reference to occupation in the fatwa referred to US forces based in Saudi Arabia for the purpose of controlling air space in Iraq, known as Operation Southern Watch.The AKS-74U in the background is a symbol of the mujadin's victory over the Soviets, since these weapons were captured from Spetsnaz forces. Their advice was heeded.In 1992, hundreds of volunteers joined an all-mujahedeen unit called El Moujahed in an abandoned hillside factory, a compound with a hospital and prayer hall.Khalil al-Deek was arrested in Jordan in late December 1999 on suspicion of involvement in a plot to blow up tourist sites. A second man with Bosnian citizenship, Hamid Aich, lived in Canada at the same time as Atmani and worked for a charity associated with Osama bin Laden. In its June 26, 1997, a report on the bombing of the Al Khobar building in Riyadh, Saudi Arabia, The New York Times noted that those arrested confessed to serving with Bosnian Muslim forces.This information was denied by the Bosnian government following the September 11 attacks, but it was later found that Aodouni was arrested in Turkey and that at that time he possessed the Bosnian passport. The three, one of whom was identified as Imad El Misri, were Egyptian nationals. The paper said that two of the suspects were holding Bosnian passports.He claimed bin Laden had used Albania as a launchpad for violence in the region and Europe. He claimed that they had informed Richard Holbrooke that KLA was being aided by al-Qaeda but the US decided to cooperate with the KLA and thus indirectly with Osama despite the 1998 United States embassy bombings earlier.

Our umma has known this humiliation and contempt for over eighty years. Its sons are killed, its blood is spilled, its holy sites are attacked, and it is not governed according to Allah's command.Bin Laden was among a group of thirteen fugitive terrorists wanted on that latter list for questioning about the 1998 embassy bombings. Bin Laden remains the only fugitive ever to be listed on both FBI fugitive lists.They did however offer to try him before an Islamic court if evidence of Osama bin Laden's involvement in the September 11 attacks was provided. It was not until eight days after the bombing of Afghanistan began in October 2001 that the Taliban finally did offer to turn over Osama bin Laden to a third-party country for trial in return for the United States ending the bombing.The military was drawn to the area after receiving intelligence of a pre- Ramadan meeting held by al-Qaeda members.We will crush al-Qaeda.One week later, General Stanley McChrystal, the top U.S. commander in Afghanistan said in December 2009 that al-Qaeda would not be defeated unless its leader, Osama bin Laden, were captured or killed.Numerous speculative press reports were issued about his whereabouts or even death; some placed bin Laden in different locations during overlapping time periods. None were ever definitively proven. After military offensives in Afghanistan failed to uncover his whereabouts, Pakistan was regularly identified as his suspected hiding place. Some of the conflicting reports regarding bin Laden's whereabouts and mistaken claims about his death follow:In the letter, translated by the United States military's Combating Terrorism Center at West Point, Atiyah instructs Zarqawi to send messengers to Waziristan so that they meet with the brothers of the leadership.The detainee reported that in January or February (2009) he met a trusted contact who had seen bin Laden in Afghanistan about 15 to 20 days earlier.

The agenda included a discussion of a possible Saudi role in Karzai's plan to reintegrate Taliban militants.Of the groups affiliated with al-Qaeda, Bin Laden condemned Tehrik-i-Taliban Pakistan for an attack on members of a hostile tribe, declaring that the operation is not justified, as there were casualties of noncombatants. Bin Laden wrote that the tatarrus doctrine needs to be revisited based on the modern-day context and clear boundaries established. He asked a subordinate to draw up a jihadist code of conduct that would constrain military operations in order to avoid civilian casualties. In Yemen, Bin Laden urged his allies to seek a truce that would bring the country stability or would at least show the people that we are careful in keeping the Muslims safe on the basis of peace. In Somalia, he called attention to the extreme poverty caused by constant warfare, and he advised al-Shabab to pursue economic development.Cambridge University Press. p. 74. ISBN 978-1-107-02209-6.

In the Eastern Orthodox Church iconography, the image is known as the ”Virgin Theotokos of the Passion” due to the instruments of the Passion of Jesus Christ present on the image. They preach the gospel to the poor and most abandoned in a wounded world. They spread the gospel from the slums of Abuja to the rural hamlets of the Mississippi Delta. In all they do they are inspired by a deep devotion to Our Mother of Perpetual Help. Out of this devotion, the Redemptorists created Mary Pray for Us. It is our profound prayer that all who visit this website will also feel the joy of Our Mother’s constant presence and protection in their lives. Please also join in the Church’s evangelical mission by telling a friend about Our Mother of Perpetual Help. God bless you!

Do not operate the motor if you do not want to be completely responsible for any damage or injury incurred or caused during its operation. Read all instructions before operating your motor. If you have any questions about any aspect of operating this motor, do not attempt to start or operate it. Never operate the motor, or fly, alone. When operating the motor, never stand, or allow anyone else to stand, in front of, or to the side of the propeller. Always stand behind the propeller. Keep away from the prop while operating the motor. Do not wear loose clothing near the motor or prop. Do not run the motor near loose material such as dirt, gravel, power cords, ropes, sand, etc. Loose material can be drawn into the turning prop causing injury or damage. Always operate the motor in an open area.

Do not operate indoors. This motor can develop tremendous thrust. Make sure the aircraft is properly secured when starting or operating the motor. This motor can stop at any time, for a variety of reasons. Do not fly your plane in a way that damage or harm will result if the motor stops running. Inspect motor mount bolts and firewall integrity before operating the motor. Anyone in the immediate area of the motor should use eye protection during operation of the motor. Keep spectators at least 30 feet away when operating the motor. Turn off the motor before making any adjustments. Always use the proper size propeller. Never use a damaged, modified, or repaired propeller. Always use the correct length propeller bolts. Do not use spacers behind the propeller. Spinner cones must not touch the propeller. Thinner props may require using shorter prop bolts, especially if not using a spinner back plate. Make sure your prop bolts do not bottom out in the propeller hub. Check that the propeller bolts are tight before every flight. Always install an ignition kill switch to stop the motor. Adjust the carburetor linkage so that the motor will stop when the carburetor is completely closed. Gasoline is extremely flammable. Be careful of any sparks from electrical contacts such as fuel pumps, battery chargers, etc. Do not allow smoking in the area of your fuel supply or motor. Store fuel in approved containers and in well ventilated areas. Allow the motor to cool before touching or fueling. Always turn the prop a few revolutions after running the motor to discharge the ignition system. The ignition system develops extremely high voltage. Do not touch it during operation. Remember! This motor can stop at any time, for a variety of reasons. Desert Aircraft will not be responsible for damage caused in engine out situations. 1 3 Mounting the Engine The DA85 features a rear induction carburetor that is intended to protrude or breathe through the fire wall.

While mounting and initial setup of the engine and with the carb through the firewall can take some extra work, this carburetor location provides a stable air environment for consistent high performance, while greatly reducing carburetor noise. We do not recommend using standoffs or spacers to mount the DA85. Vibration and stress to the engine case increase when standoffs are used. Damage from using standoffs or spacers will not be covered under warranty. If you still elect to use shims or spacers between the rear of the engine and the firewall, make sure that the mounting faces of all the spacers or shims are flush with the rear of the engine. If the face of all spacers are not in the same plane or perfectly flush with the rear mounting face of the motor, the crankcase may be damaged. Again, this will not be covered under warranty. Make sure the carburetor has adequate clearance near the inlet to allow an unobstructed airflow into the carburetor. If the carburetor is located in front of a former or firewall, be sure there is at least 1 (25mm) of clearance from the carburetor inlet. If there is less than 1 clearance, make a hole larger than the carburetor inlet diameter in the former or firewall. The throttle arm is tapped for a 2-56 SAE ball link. If you wish, the throttle return spring can be released or cut on one end, but not removed. Without the spring, vibration will wear and damage the shaft and carb plate. The choke lever can be actuated by hand with a small light weight pushrod or by a small servo behind the firewall. There are two arms on the choke shaft. One is removable and can be repositioned to give proper geometry for linkage access from the bottom or rear. Do not remove the detent ball and spring on the choke shaft. We do not recommend soft mounting the engine as it can cause problems with exhaust systems and carburetor linkages. Check the mounting bolts regularly to insure they are tight.
