Answer: Any commercial propeller for either gas or electric models may be used. Props may be cut to reduce their diameter but the blades may not be reduced in thickness (such as by sanding the airfoils to a new profile) or in chord (such as by trimming the trailing edges). Answer: The "Over the Counter" refers to the individual cells. This is a change from the rule for the 1996/97 contest year. Answer: This is a feature available in many production RC radio systems.

The Home Ventilating Institute (HVI), a trade association representing the manufacturers of 95% of the residential fans in North America, recommends that a bathroom exhaust fan be selected that is capable of providing eight air changes per hour (ACH). Most building codes only require a minimum airflow of 50 cfm from a bathroom, with a capacity of providing five ACH.

Answer: AEDs are external devices that can be used by minimally trained laypersons in emergency situations. They not only administer an electrical shock, but also read the heart rhythm patterns of the patient. This significantly reduces the amount of training needed for their effective use and allows people with minimal training to perform defibrillation in emergency situations with little risk of additional injury to the patient.

Answer: The definitive treatment for external Piles remains surgery. In case, external Piles is associated with internal Piles (known as intero-external Piles), ThankGod Piles Management System could be of help.

Answer: Adding ducts or pipe work will cause heat build up in the heater causing poor combustion and the motor to burn out. Adding ducts or pipes to the heater will void the warranty.

A - Large diameter, slow rotating propellers can be highly efficient for thrust but cannot be used to also produce air at the pressure needed for the air cushion. If one is prepared to build in additional pulleys and a second fan for lift and a second bearing system, it will work. Canair is a strong believer in vehicle safety, not only for the pilot and passengers, but for the others outside the craft. Adequately guarding large propellers is not easy.

To replace a failed fan without doing a major ceiling job. Use the existing housing as an intake grille.

Answer: The fair use doctrine says that otherwise copyrighted works may be used for purposes such as criticism, comment, news reporting, teaching, scholarship, or research.

While not quite a fan club, the Magian Line is being set up to keep track of what's happening with Sandman and Neil Gaiman. It has the benefit of having Neil's stamp of approval. Three issues have been published so far. Each has contained an interview with Gaiman and original artwork by such artists as Jill Thompson, Mike Dringenberg, Matt Wagner, Mark Buckingham, Bryan Talbot and other noted Sandartists. T-Shirt (Dave McKean art of Dream with logo on back.

NFPA 96 states the following: 5-1.3 ...The fan shall be connected to the exhaust duct by flanges securely bolted as shown in Figures 5-1.2(b), (c), (d), or (e) or by a system specifically listed for such use. Flexible connectors shall not be used.

Answer: No. The rules clearly state "Contest aircraft must comply with all aspects of the following specification:" which includes both flight missions and both ground tasks. Answer: The latches must be sufficient to allow lifting the box by the lid when closed (it is recommended that teams install handles on the top of their box to make it easier to demonstrate).

Answer: External pods (wing or fuselage mounted) may NOT be used for carrying the payload. (rev 22Oct02) Answer: No. The internal water tank may be of any construction as long as it's capacity is 4 Liters or less (which will be verified during the technical inspections). Answer: You may use a commercial electronically controlled valve, may fabricate your own servo controlled valve, or any combination of commercial and fabricated parts.

Answer: No. The 1/3 , 2/3 distribution applies to the team as a whole, from the entry date through the end of the contest. Not all team members must be present at the fly-off.

The soul enters our body within 24 to 48 hours before or afer birth. This soul can, and will, leave the body frequently to learn from its Higher Self and Masters and Guides. All dream levels are OBEs, during which our soul is able to learn on the Astral Plane and grow spiritually, hopefully. I do not feel that karma and reincarnation conflict with any form of theism.

Moving your CG back will not decrease your sink rate. It will however, make your model more sensitve in pitch. You can fly slower and the model will send you a clear message when it contacts lift. Move it too far back and you are likely to experience a "tuck under". Remember to adjust you declage if you move your CG otherwise you will lose efficiency.

Answer: On most Tecnadyne thrusters, the propellers are held in place with a simple E-clip that can be removed with the fingers or with a screwdriver. On the Model 260 & Model 300 thrusters, the propeller is held in place with a shoulder bolt that requires a 1/8in Allen key (provided with the thrusters) to remove.

In-Duct Air Purifiers utilize the fan or air exchange unit in your existing HVAC system. This reduces operating cost since it doesn't contain a fan. When contaminants enter your HVAC system and pass over the In-Duct Air Purifier's UV lamp, they are destroyed. Air coming from your HVAC system will have low levels of negative ions and ozone. These will oxidize airborne particulates, eliminate odors, and break down other unhealthy fumes and organic contaminants.

This is not recommended. It will cause the fan to run harder, greatly reducing the CFM performance of the fan and create excess noise.

Dirt, dust and lint collect in the heating and cooling system(s) of all forced air systems. Every heating or cooling system depends on the flow of air. As this air circulates, it picks up some of the lint, dust particles, cobwebs and other kinds of dirt, which normally occur in every home or business (regardless of the furnace), and deposits it within the ductwork where it collects and builds up. Dirt, dust and debris fall into vents and make their way into the ductwork.

That means your ticket was purchased via the U2.com Fan Club presale. If you have a GA ticket, it means you can lineup in the U2.com Fan Club line (if it exists). It might also mean you gain entry into the venue earlier, but that's not necessarily the case at all venues. It does NOT mean you have a better chance at getting into the ellipse. And, it should be noted, the Fan Club line is quite often longer than the non-fan club line.

X-Plane 8's scenery engine is brand new; we have not had very much time to performance tune and optimize scenery loading. Once the global scenery is done, we will be tuning the code. X-Plane 8 should eventually exceed the load times of X-Plane 7; performance improvements will be availabine in the form of free X-Plane 8 point releases.

No, Dan currently does not have an official fan club. However, you are welcome to write to him!. [return to top]

The fan helps circulate heat throughout your home. A ceiling fan is also a good alternative to a fan fitted to the heater.

Answer: According to the rules of General Administration of Civil Aviation, on domestic flight in China passengers holding an economy class ticket are allowed to bring 20 kg (about 44 lbs) of luggage (both checked and carry-on luggage) free of charge. For more details, please read this page:

Answer: Airline policy for lost tickets vary according to the individual airline. Contact the airline you are flying with for specific information.

Answer: It's a labor of love. People do it for that reason. And other aspects - and challenges like construction, engineering, testing, and flying. Being self-sufficient. Trailering your own plane, with its foldable wings from your garage to the clear blue skies can be a real achievement. That you did it yourself! What it requires is a simple knowledge of plans. Some parts are easy. Some parts, perhaps are hard. It depends on your background and skills.

Hartzell Propeller Inc. manufactures only controllable and constant speed, hydraulically actuated propellers for power plants that range from 150shp (reciprocating) to 2180shp (gas turbines). A constant speed propeller system is controlled by an engine speed-sensing device (governor), to maintain a constant engine/propeller RPM by changing blade pitch. The governor uses an internal pump that is driven by the engine. This pump increases engine oil pressure for supply to the propeller.
