How To Hover RC Helicopters

By Oliver Kiev


The main goal of hovering an RC helicopter is to keep it in one spot with as little relocating or wandering as possible. Eventually, you 'd like it to continue to be definitely motionless, but in a non ideal globe, that's nearly impossible as there are too many elements that will cause drift or movement. For the novice pilot hovering an RC helicopter can show to be exceedingly tough and lots of people quit on the hobby since they cannot understand hovering. While it is feasible and people do fly RC helicopters without being able to float appropriately, it's not advised. It's like discovering to run prior to you could walk and you'll at some point run into an issue. Having the ability to hover instructs control and fine motor abilities that you'll wish to have to become a better overall pilot. Even leading entertainers practice hovering to develop their skills. There are 4 main hovering positions, or 8 if you count inverted hovering, but I'm not getting into that as it's a lot more complex than finding out standard, right side up floating that we'll go over in this 'ways to' short article ... Tail in hovering 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 far 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 contrary, 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

Before you can discover to float your RC helicopter, you have to ensure your helicopter and radio is effectively setup. If unsure, get in touch with a skilled pilot or your neighborhood hobby store. Put your training gear on. If you don't have some, buy it. It costs $ 20 - $ 50 and if you're just starting will save you hundreds in crash loss. The training gear likewise makes a good visual aid that help you see the throwing and rolling of your RC helicopter before you observe them in your helicopter. If you're flying a nitro helicopter, have lots of fuel readily available. If you're going electric, see to it your batteries are charged and have more than one readily available if possible. The even more you can fly continuously, the much faster you'll enhance your abilities.

Ensure your gyro is set to heading hold mode. While some individuals suggest flying with a gyro in rate mode since you'll get a much better feel for the helicopter, I do not suggest it for the easy reason that unless you intend on constructing scale ships, you'll probably never utilize rate mode, so there's no sense finding out to fly with it. Also, ensure your radio and helicopter is set up for hovering which it's not too sensitive. If it's too sensitive or quick to react, you could try including some exposition to the cyclic to relax the remain their centres, or decrease the endpoints to lower the amount of cyclic pitch and responsiveness of the helicopter. And finally, undergo 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 can now hover an RC helicopter ... everything else is downhill from here. Though you'll most likely wish to undergo a minimum of 3 - 5 batteries or storage tanks of fuel exercising fixed hovering prior to you begin to move your helicopter around to see to it you'll be able to react in time in case of a mishap. As s side note, when engaging in hovering, you'll generally wish to hover above 2 - 3ft to avoid ground result. Ground impact is when your RC helicopter is hovered close to the ground (under one rotor diameter) and the downwash of the rotor cutters produces a high pressure bubble of air. This bubble of air applies an unequal upwards force which causes the helicopter to wobble or relocate sideways making steady flight difficult. It's a little like stabilizing a basketball on your finger (when it's not spinning). For those reasons, when engaging in hovering, I prefer to float at about 3 - 5ft. It's high enough to prevent the ground impact and low enough that I'm looking a little down at the helicopter and could make use of the ground as a reference. The higher you get, the more difficult it is to view depth and keep the helicopter in one location - there's additionally no easily perceivable frame of reference against the sky as there is on the ground. Nonetheless, with that being stated, if you're simply starting you may wish to hover a little higher in case you slip up so you have time to recover. Many individuals make use of the saying "practice 2 blunders high" meaning that you have time to recover from at least 2 errors before your helicopter becomes acquainted with the ground, the hard way. Pointer: Make use of a simulator for exercising and as soon as you're comfortable on your computer system try it on your RC helicopter. As soon as you're able to effortlessly float your RC helicopter tail in, it's time to begin moving it around a little. Repeat the same left/right forwards/backwards and diagonal movements that you did in the previous area, but this time your helicopter will be 2-3ft in the air and when you get to your new position, hold it there for 15-20 seconds prior to moving on. Transitioning from flight to floating will help to improve your skills and take you to the next action. Fixed side in and nose in floating is considerably more difficult than the tail in floating workouts discussed in this write-up since cyclic commands are 90 or 180 degrees off depending on the position. For example, when nose in hovering, if you input a right cyclic command, your helicopter will transfer to the left and vice versa, so I'll save them for another time.

Now go out there and enjoy your Remote Helicopter!
