Guide To Hovering RC Helicopters
by Oliver Kiev
The major objective of floating an RC helicopter is to keep it in one spot with as little moving or drifting as feasible. Eventually, you 'd like it to remain definitely motionless, however in a non best globe, that's almost impossible as there are a lot of elements that will cause drift or motion. For the beginner pilot hovering an RC helicopter can show to be exceedingly challenging and many individuals quit on the hobby since they cannot master hovering. While it is feasible and individuals do fly RC helicopters without being able to hover correctly, it's not advised. It's like finding out to run prior to you could walk and you'll at some point encounter a trouble. Having the ability to hover teaches control and fine motor abilities that you'll wish to have to become a better total pilot. Even top performers practice floating to sharpen their abilities. There are 4 primary floating positions, or 8 if you count inverted floating, however I'm not going to get into that as it's a whole lot more complicated than finding out basic, right side up hovering that we'll go over in this 'how to' write-up ... Tail in floating is where the tail is pointing towards you and the nose of your helicopter is far from you. Nose in is the reverse - where the nose of your helicopter is pointing to you and the tail is pointing away from you. Right side in is where the nose is indicating the right, the tail is indicating the left and you're dealing with the right side of the helicopter. Left side is the opposite, where the nose is pointing to the left, the tail to the right and you're dealing with the left side of the helicopter.
Pre-flight Setup & Checklist
Prior to you could discover to hover your RC helicopter, you should ensure your helicopter and radio is appropriately setup. If not sure, get in touch with a knowledgeable pilot or your local hobby store. Put your training gear on. If you do not have some, buy it. It costs $ 20 - $ 50 and if you're simply starting out will save you hundreds in crash damages. The training gear additionally makes a great aesthetic help that help you see the pitching and rolling of your RC helicopter prior to you notice them in your helicopter. If you're flying a nitro helicopter, have lots of fuel available. If you're going electric, see to it your batteries are charged and have more than one available if possible. The even more you could fly continually, the quicker you'll improve your abilities.
Ensure your gyro is set to heading hold mode. While some people suggest flying with a gyro in rate mode since you'll get a much better feel for the helicopter, I do not recommend it for the simple reason that unless you plan on developing scale ships, you'll most likely never make use of rate mode, so there's no sense discovering to fly with it. Likewise, see to it your radio and helicopter is set up for hovering which it's not too delicate. If it's too delicate or fast to react, you could attempt including some expo to the cyclic to relax the sticks around their centres, or lower the endpoints to reduce the quantity of cyclic pitch and responsiveness of the helicopter. And lastly, experience your preflght checks.
Getting a Feel for Your Helicopter
Prior to you learn to hover, you need to understand how your RC helicopter works. When you move the sticks, exactly how does your helicopter react? If you input right cyclic, how rapidly does your helicopter respond? The objective is to discover exactly how your helicopter steps and corresponds with the inputs you offer. When your RC helicopter and radio are setup, you'll need a practice area. You're going to want the area you're engaging in on to be as smooth as feasible so you can slide around a bit. A gym flooring, a big and smooth cement basement, a ice rink or a smooth asphalt make the best practice surfaces - the smoother the much better. If you're attempting to discover on a rough or unequal area like grass or gravel, your RC helicopter could catch on it and tip over. The training gear will help you slide around without anxiety or tippage. See to it you have at least a 10ft x 10ft (20ft x 20ft or larger advised) area that is clear of any and all obstructions. The bigger your helicopter is, the more area you'll need. If there's no marking to utilize as a reference point, use a marker or concealing tape to create one. Put your helicopter into the middle of the space pointing into the wind (if outdoors) and stand 10 - 15ft behind it. Start to throttle up really slowly - you don't want it to lift off the ground, simply get it light on the training gear so you could slide it around. If your primary cutters rotate clockwise and your helicopter has been developed effectively, there's a likelihood that it will wish to wander somewhat to the left to counteract the tail rotor thrust pushing to the right. If your rotors spin counter clockwise, your helicopter must drift slightly to the right. Use the trims to compensate for the wandering until your RC helicopter remains relatively stationery. Once you have actually got the trims set, give a bit right cyclic input and watch as the helicopter transfers to the right. Then provide left cyclic input to move it back to the reference point. Then do the same thing relocating your helicopter forwards and backwards. The major goal right here is to get a feel for how the helicopter responds to your stick inputs and how much input is necessary to get it to relocate. You'll discover small stick inputs are all that is required. Once you're comfortable with side to side and forwards / backwards movement, bring the helicopter back to your reference point and move it diagonally in all 4 directions. This will be a lot more difficult then left/right forwards/backwards motion since you'll be inputting numerous cyclic commands all at once in addition to managing the tail. You'll wish to practice this until you can make very precise movements and are comfortable relocating your helicopter around. Keep in mind to always fly your helicopter by watching its nose, never by considering the tail boom.
Learning To Hover All right ... on to the excellent stuff.
Once you've got a feel for exactly how your helicopter relocations and ways to control it utilizing your radio, it's time to get it off the ground. For this, you'll want to move from your hassle-free area to something softer, more effective short lawn. This will help to absorb any influence from hard landings and avoid damage. If you have a truly small or micro RC helicopter, you can do this on the same tough surface you utilized previously as there's not much weight to cause damage. Select or mark a reference spot and spot your helicopter there going through all the pre-flight checks mentioned earlier. Input cumulative till your helicopter is simply a few inches off the ground and attempt to hold it there. Remember that very small inputs make a huge distinction, so be gentle on the controls. Observe your helicopter and the balls on the training gear and try to expect any movement and try to compensate for it ahead of time. To become a masterful hoverer you have to have the ability to inform exactly what's going to occur in terms of movement and react to it in advance to prevent it from taking place. As you become more comfortable, begin to bring it a little higher and higher till you get it up to 2 - 3ft and could hold it in one spot.
Congratulations !!!
You could now float an RC helicopter ... every little thing else is downhill from here. Though you'll probably wish to go through at least 3 - 5 batteries or tanks of fuel engaging in stationary hovering before you begin to relocate your helicopter around to make sure you'll be able to respond in time in case of a mishap. As s side note, when engaging in floating, you'll usually wish to hover above 2 - 3ft to prevent ground impact. Ground result is when your RC helicopter is hovered close to the ground (under one rotor diameter) and the downwash of the rotor blades develops a high pressure bubble of air. This bubble of air applies an uneven upwards force which causes the helicopter to wobble or relocate sideways making stable air travel difficult. It's a bit like stabilizing a basketball on your finger (when it's not spinning). For those reasons, when exercising floating, I like to hover at about 3 - 5ft. It's high enough to avoid the ground impact and reduced enough that I'm looking a little down at the helicopter and can use the ground as a reference. The greater you get, the more difficult it is to regard depth and keep the helicopter in one spot - there's additionally no effortlessly perceivable frame of reference against the sky as there is on the ground. Nonetheless, with that being stated, if you're simply beginning you might wish to hover a little higher in case you make a mistake so you have time to recover. Many people utilize the stating "practice 2 mistakes high" meaning that you have time to recover from at least two blunders before your helicopter comes to be familiarized with the ground, the hard way. Idea: Make use of a simulator for exercising and when you're comfortable on your computer attempt it on your RC helicopter. When you have the ability to quickly hover your RC helicopter tail in, it's time to start moving it around a little. Repeat the same left/right forwards/backwards and diagonal movements that you finished the previous area, however this time your helicopter will be 2-3ft in the air and when you get to your brand-new position, hold it there for 15-20 seconds prior to moving on. Transitioning from flight to floating will help to improve your abilities and take you to the next step. Stationary side in and nose in hovering is considerably more difficult than the tail in floating workouts pointed out in this short article since cyclic commands are 90 or 180 degrees off depending on the position. For example, when nose in floating, if you input a right cyclic command, your helicopter will relocate to the left and vice versa, so I'll conserve them for another time.
Now go out there and enjoy your Remote Control Helicopter!
