In the old days, back when only full size rc helicopters were available, and mini rc helicopters were a hopeful fantasy, it took a lot of space in one’s trunk just to transport the necessary gear. Mini rc helicopters do not require very much transport space, and due to their small size, can be set up to fly in a matter of seconds. There is likewise no need to spend time driving to an open flying field, as mini rc helicopters actually fly better when inside confined spaces such as rooms and office spaces. A gust of moving air, such as wind from fans and air conditioners can cause these little wonders to wobble about their vertical axis, creating precession-related forces that can send them spinning out of control. In the same vein, it is likewise not recommended that they be flown near exhaust vents, as mini rc helicopters are light enough to be sucked through and chopped into mini rc helicopter salad.
Most cheap mini rc helicopters have two flight control channels, which manage throttle and anti-torque rotor. This means that these types of mini rc helicopters can be made to take off and land, and turn. Unlike a real helicopter, they cannot be made to hover backwards and sideways, as the rotor disc cannot be tilted in any direction. Although there are mini rc helicopters with full control characteristics, but they are in a higher price range.
Two channel types of mini rc helicopters are best trimmed or fitted with nose weights so that they fly forward slowly, with the “pilot” using available control to determine the proper glide slope for a landing on a spot. Another technique is to twist the tail boom (assuming the same is flexible) so that the anti-torque rotor is blowing air slightly downward. This lifts the tail up during flight, casing the helicopter to move forward in speed proportionate to the power applied to the main rotor. When flying mini rc helicopters with this technique, maintaining a right orbit is recommended, as it normally gives the pilot better control over fine control inputs. Continue making circles over you intended landing spot while gently reducing power so that the helicopter comes to rest in the approximate area you want it to land on. While not exactly a precise way to land the helicopter, it is probably the best available method considering the craft’s control limitations. In any event, it really impresses people to see such tiny little mini rc helicopters take off and land on an office desk.
