Q: No matter how tricked out your RC car is, it can only go so fast with a subpar battery. If you really want to leave your competition in the dust, opt for a battery with a greater voltage capacity, such as a nickel-metal hydride (NiMH) lithium-polymer (Li-Po) pack. RC cars have been known to attain speeds of up to 100mph (160km/h) with cranked-up batteries. You can potentially add 1520mph (24.132.2km/h) to your car's top speed by upgrading the battery, even without making any other modifications. To ensure that you get the right fit, measure your car's battery compartment and buy a battery of the appropriate size. When it comes to working with high-output batteries, a little boost goes a long way. Start smallif your car came equipped with a single cell battery, move up to a 2-cell or 3-cell. You can then increase the voltage incrementally from there, provided your motor can handle the jump. If your car feels unusually hot after a session, it may mean that the upgraded battery is placing too much strain on the motor. In this situation, it's safest to just move down a size, since you won't be able to effectively make use of the extra power anyway. Using a battery that's too powerful for your car could cause permanent damage to to the motor or ESC. Pinch the connectors at the end of the colored wires and slide them out of the ports. Take out the battery and set it aside. You can put it into storage as a backup power source, or toss it out to free up room in your tool kit for superior packs. If you decide to keep your old battery, perform a before-and-after test run alongside the new one. You'll most likely be surprised by the difference the sleeker, higher-output battery makes. Make sure you take your old batteries to the proper waste disposal or recycling site when it's time to get rid of them. Never throw rechargeable batteries in the trash. Insert the battery carefully, matching up the wires according to color. Slide the connectors into the ports until they click. Replace the battery cover, if your model has one, then switch the car on and take it for a spin. Test the battery's fit to make sure there are no loose connections or unnecessary movement in the pack itself. It's important to be systematic about replenishing the cells in your new battery in order to keep it performing at its best. After every few hours of use, plug the battery pack into a dedicated charging unit and give it some juice. It's also a good idea to charge batteries after they've been exposed to colder temperatures or have been in storage for a while. Make sure your RC car's battery is fully charged before you take it out for a practice session or race. If possible, pick up an extra battery or two so you'll always have a spare on hand.
A: Purchase a high-output battery. Make sure your motor can handle the extra power. Remove the existing battery. Place the new battery into the compartment. Charge your battery regularly.

Q: Boil 7 cups of water then add 1 teaspoon Ajwain, 1 teaspoon cumin seed, 4 teaspoons salt, 4-5 teaspoons green chili, 2 tablespoons sesame seeds, and 3 teaspoons papad kharo or baking soda. Stir everything together and turn down the heat. Add 4 cups of rice flour to the mixture of water and spices. Turn the heat back up and bring it back to a boil. Mix the flour with a wooden spoon then turn the heat off. Continue to mix the rice flour until it is a dough consistency. Take a chunk of dough and press it into a flat ball. Press two indents in it with your finger. Do this with all of the dough. Set around three chunks of dough on the plate at a time. Put the plate over a pot of water. Put a lid on top of the plate and bring the water to a boil. Cook for about 10-15 minutes. When the dough is finished cooking, put the dough chunks in a bowl. Cut the cooked dough into smaller pieces then mash it with the bottom of a glass. Mash the dough quickly before it gets cold. Make sure there are no lumps in the dough and that it is smooth. Roll the dough balls into spheres then flatten them. The easiest way to flatten them is with a peri press. If you don't have a peri press, you can use a rolling pin or a flat and heavy object. Cover the dough with a piece of saran wrap before you flatten it to avoid the dough getting stuck.
A: Boil water and spices. Add rice flour to the water and spice mixture. Separate the dough into pieces. Cook the dough over boiling water. Cut and mash the dough. Flatten the dough into papads.

Q: Tight neck muscles is a reason some people try to crack their neck, likely in efforts to reduce the tension and discomfort they feel. Instead of trying to constantly release the joints of your cervical spine, gently stretch your neck muscles, which might alleviate your neck issue and eliminate the urge to crack it. Use slow, steady movements and take deep breaths during your stretches. In general, hold stretches for about 30 seconds and repeat 3-5x daily. Stretching directly after a warm shower or the application of moist heat is recommended because your neck muscles will be more pliable. While standing, reach around your back with your right arm and grab a little above your left wrist. Gently pull on your left wrist while laterally flexing your neck in the opposite direction, such that your right ear approaches your right shoulder. Hold for 30 seconds, then do the other side. If your neck is stiff and has poor range of motion, then maybe the problem is more joint related. In this case, trying to crack (or unjam) your neck joints is certainly warranted, but typically the stiffest joints don't release with self manipulation. Instead, the joints above and below the stiffest joint keep cracking, which may make them a little too loose (hypermobile) and unstable over time. Start with moving your head in circles, first clockwise and then counterclockwise, for about 5-10 minutes each way. You may hear some clicks, cracks and pops in your neck, but focus on the movement and not the sounds. Target the main movements of your neck: forward flexion (looking down at your toes), lateral flexion (ear towards your shoulders) and extension (looking up towards the sky). Go as far as you can in each of the four directions about 10x daily. After a week or two, you should notice an increase in range of motion, which might negate the desire to constantly crack your neck. Strengthening the muscles of the neck is good for stability. Muscles are not only for movement, but they are also important for providing protection and stability to the bones and joints that lay underneath them. Weak neck muscles increase the amount of instability in the cervical spine, which might trigger the desire to crack the spinal joints. Consequently, strengthening the cervical muscles may diminish the desire to crack them. Tie an elastic exercise band around your head and attach it to something stable that's at the level of your head. Walk a few steps away from it until you feel tension in the exercise band. Then do the four main neck movements (flexion, extension, right / left lateral flexion) under tension 10x each on a daily basis. After a week or so, change to a thicker exercise band with more tension. Alternatively, see a physical therapist, who can show you specific and tailored stretches and strengthening exercises for your neck.
