When you start out discovering to fly radio managed design helicopters you are immediately faced by a wide range of choices. One of the very first things you will notice is that you get 2 standard types of radio managed helicopters to select from particularly those with a single rotor and those with a double set of primary rotors, the coaxial RC helicopter.
Within each of those groups you will likewise find several variations, which may make little sense initially glance.
The Coaxial RC Helicopter
I will focus here on the coaxial RC helicopter and highlight the differences within this group, and mention some of the advantages of discovering your RC helicopter controls on this type of radio regulated model helicopter.
When I started checking out you could find a RC helicopter in many toy shops. One of the popular types you will certainly discover in toy stores is the configuration with a horizontal tail rotor driven by a tiny electrical engine sitting right under the tail rotor.
Although this type of RC helicopter – a few of the smaller sized ones are really infra-red regulated – can be flown effectively, it has relatively restricted maneuverability. The forward and backwards activities are controlled by the horizontal tail rotor: rotating in one direction will lift the tail up and press the heli forward. Rotating in the other direction will push the tail down and drag the heli in reverse.
Turning this heli occurs by pointing the nose in the direction you want to go, and this is regulated by the distinction in rotating speeds of the 2 main rotors. The heli will kip down the rotational direction of the slower rotor.
The downside with this horizontal tail rotor arrangement? This heli cannot bank in a turn as would be necessary in a quicker turn. I also discovered control difficulties as the tail wants to “surpass” the major rotor in forward air travel. It was a lot easier to fly in reverse as the tail rotor would basically pull the remainder of the device along.
I attempted my level best, however I could not coax any serious controlled flight out of my toy coaxial helicopter, and I essentially composed it off within days of putting in major effort to manage it appropriately. The toy shop likewise didn’t carry spares!
So, What Follows?
I decided to offer the toy store a rest and popped into the local pastime store. There the guys showed me a various sort of coaxial RC helicopter, a far more significant machine with a “reality” swash plate. Without going into a lot of information, the swash plate makes it possible for the heli to bank in any direction by tilting the entire rotor (all-time low among the 2 counter-rotating major rotors) on command from the radio transmitter.
Since of that swash plate this coaxial heli doesn’t utilize a tail rotor to propel it in a direction.
I bought this pastime grade helicopter – a ‘Nine Eagles Swordfish’ – and discovered it astonishingly maneuverable, and in a brief time I managed to find out the basics of RC helicopter controls, all the while having a lot of enjoyable both indoors and outside!
Neels prefers to fly RC helicopters – as well as to write about flying them! You can see some action photos here of his first coaxial helicopter models, the toy helicopter and the Swordfish, along with photos and videos of his newest venture: the collective pitch helicopter, inluding a free ebook revealing you the best ways to make your very own training equipment for your helicopter!
