Q: To do this, you need to write down the measurements of the deep end and the shallow end of the pool and divide the result by two. Let's say the shallow end of the pool measures 3 feet and the deep end measures 8 feet. (3 + 8)/2 = 5.5. The average depth of the pool is 5.5 feet. Now, just take this number and multiply it by the length and width of the pool. You're really just multiplying the area of the bottom of the pool by its depth. Let's say that the width of the pool is 20 feet and the length is 40 feet. So, 5.5 x 40 x 20 = 4,400 cubic feet. To convert the answer to gallons, simply multiply the answer by 7.48. 4,400 x 7.48 = 32, 912 gallons of water. You're all done.
A: Find the average depth of the pool. Multiply the result by the length and width of the pool. Convert the answer to gallons.

Q: You need a wide open space, preferably a field, with no buildings or trees around.  The number or people in the area should also be limited, as the functioning of an RC helicopter can be extremely dangerous.  The size of the space you'll need will differ depending on the size of your helicopter.  You can either go out by yourself, or go with one other person.  Distractions such as pranks, games, or laughs can dampen your ability to focus on flying your copter. Dogs and other pets should also be left at home.  There are many horror stories where pets are killed by falling aircraft.  Do not let this happen to one of your pets. the area size should be at least 60X60 feet.  The best ground material is clean, smooth pavement, or tightly packed snow. If you are someone who is new to flying, you will need to attach this equipment onto the bottom of your helicopter.  The training equipment is typically two wooden or carbon fiber sticks, crossed in a "T" shape, with little rubber balls on the ends.  These can be purchased at helicopter specialty stores, both online and on site, for around 40-60 dollars.

You will need to make sure that your receiver batteries, helicopter, and radio are all charged up before you go out to fly your RC helicopter.  You will also need to check the weather before you go out.  If the weather is anything above 15 mph wind, and/or light rain, you should avoid flying your copter.    You should also bring safety goggles with you when you go out to fly. If you are going to be out in an open field, especially in the fall or winter months, make sure you are wearing warm clothes.
A: Find a flying site. Purchase or make helicopter training equipment. Check for last minute precautions.

Q: When setting prices for your services, research what other businesses charge for similar services in similar communities. Remember that a working-class neighborhood will not be able to pay the same as customers in a more affluent neighborhood. You're not in business to work for free, so it's important to know the cost of doing business when determining your rates. Take into account money needed to pay for insurance, equipment and advertising, then determine how many yards you can mow each month. How much will you need to charge each potential customer to pay your costs and still make a profit? If you don't have an established clientele, you might offer lower, more competitive prices as you obtain your first few customers. Once you build a referral network and portfolio of references, you can price you services at more profitable rates.
A:
Know your market. Know your costs. Start low.
