Buyer Evaluations
I personal four SYMA helos and they all have several characteristics.
First, I bought a red S107G for 22$ and was blown away. Even so, right after a multitude of crashes related to hitting the ceiling my first one particular was starting to show put on (rotor blades dented/chiped, broken canopy brace, led not centered, vertical stabilizer cracked awaiting it next crash to come off) within one week.
Second, I bought a second 107G and it came as yellow. The very first point I noticed was the yellow one particular, while totally identical other than color, was considerably way more effective and battery lasted longer. As a result, it was a great deal more entertaining and even more hard to fly than red.
Third, becoming that I am former active duty helocopter mechanic (CH-53a,d,e, T64-GE-416) for the Marines, I purchased the S108G (Cobra). People, the Cobra is a totally different helo all together. The collective (vertical control) is not spring loaded like the S107G. Not only that, the Cobra is substantially a great deal more robust in its response and power and can be hard to manage. This is troublesome to me as the Cobra's body and frame appears to be fully plastic (as apposed to the S107 getting a metal frame). Also, the Cobra has one solid white light which I prefer to the flashing blue and red o the S107G. Since the collective is not spring loaded you can make it hover and set the controls down on a table it nonetheless flies. Quite often I forget to return the collective to zero when I crash. The Cobra has lost reception a variety of times and when it does it falls from the air and crashes. The Cobra appears to "Pop and Click" like a Marine should really--no kidding. It can speed around space significantly faster than the others and turns considerably more fast. In reality, the other seems sluggish in comparison and it is straightforward to "oversteer."
Forth, I also needed to satisfy my curiousity connected to S109 (Apache). I have located the S109 is less complicated than all to fly. It also has two white leds rather than the flashing blue and red of the S107G. The controller is the same as the S107. Overall, I actually acquire it enjoyable to reliably fly about the space with complete and utter control. I feel they did this to keep the Army from crashing out of manage--just kidding solders!
Bottom line, I give the S109 top rated rating over the other people. I do uncover the responsivness and speed of the Cobra stimulating and of interest so I rate it second. If I fly with a person else I will pick out the Cobra for its speed and responsivenees. In the finish, I do not believe the metal frame of the S107G will add considerably value as the rest of the helo is plastic and does break. The price of replacement parts cannot be justified as a new S107G presently goes for 22$.
This helicopter flew fairly nicely - for a whilst.
Syma makes a quantity of fairly slick little helicopters - I have bought several distinct models for the nephews and relatives, and every person loves them. This helicopter, the cobra, looks good and flew pretty well. All of the Symas we tried so far fly tremendously nicely out of the box. The Blackhawk and Chinook flew fairly well. The challenge with this particular (Cobra) helicopter is the landing gear. Just after a couple of crashes, the strut on 1 of the landing gear broke, meaning that on the ground, the helicopter will not stand up perfectly straight. No major deal - proper? Incorrect. If the helicopter is not standing up straight, it won't take off straight, and will quite possibly crash into a thing just before it stabilizes. The Blackhawk and Chinook have various landing gear which are alot more durable.
For those of you who are first time pilots, concentrate on hovering for your initially few flights. Just tweak the controls to try and maintain the helicopter in 1 spot. If you can master hovering, the rest gets a lot less complicated.
Syma's mini helicopters are only for indoor use. The situation with flying them outdoors is wind - the smallest puff of a breeze makes the helicpters uncontrolable.
For those of you who don't know much about Syma's RC helicopters, right here is how they work:
1. Stabilization: For true helicopters, the tail rotor controls rotation. Without having a tail rotor, a actual helicopter would be unable to turn, and would truly spin out of control. The motor for the most important rotor wants to spin the fuselage in the opposite direction of the rotation of the most important propeller. Feel about it - if you were to magically "hold" the propeller in location, the fuselage would spin. The motor of a standard helicopter, if left unchecked, would spin the propeller and the fuselage in opposite directions. In real helicopters, the tail rotor counteracts the rotational force that the primary rotor applies to the fuselage
With Syma's helicopters (other than the Chinook), they essentially have two primary propellers stacked on best of every other that have blades that are angled differently, and spin in opposite directions. Both propellers supply down force, but also generate torque on the fuselage in opposite directions. This has the impact of keeping the helicopter stable, given that the rotational forces of the two propellers on the fuselage cancel each and every other out. Syma's remote controllers come with a "Trim" control knob. This control is made use of to make sure that the two key propellers are spinning at the exact same RPM. If your helicopter's fuselage spins slightly on takeoff, use the trim knob to accurate it up.
two. Turning: In order to turn, Syma's helicopters slow down a single of the key rotors by a little amount, essentially making use of the forces described in 1 to rotate the fuselage. Turning for all of Syma's helicopters is really precise when you have them trimmed.
three. Forward/Backward motion - this is controlled by the horizontally aligned tail rotor. To go forward, the tail rotor spins, creating down force, which pushes the tail up. When the tail is up, the major rotors are angled slightly backwards, so the principal rotor pushes the helicopter forward. Reverse has the opposite impact. The tail prop pushes the tail down, which angles the thrust of the most important rotors slightly forward, which pushes the helicopter backward.
4. Sideways motion (Yaw)- Syma's helicopters don't have any mechanism for tilting the helicopter's roto sideways, so the helicopters have no capacity to move side to side. In true helicopters, the major rotor tilts forward/backward, left and suitable, and this provides the capacity for the helicopter to move in quite substantially any direction.
This Cobra heli is not as stable in flight as the Chinook or the Blackhawk. It just appears like the helicopter is a tiny too responsive.
In short, if you are a fantastic pilot, and will not crash, this helicopter is just fine. For my taste, even though, the Blackhawk and Chinook are far more durable and less difficult to fly.
1 other note - Particularly Fundamental! This helicopter comes with an further tail rotor in a plastic baggie. Save it, and put it in a safe place. The tail rotor controls forward and backward motion, and if you shed your tail prop, all you can do is hover.
