Customer Evaluations
I own four SYMA helos and they all have different characteristics.
First, I purchased a red S107G for 22$ and was blown away. Nevertheless, right after a multitude of crashes associated to hitting the ceiling my initially a single was beginning 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 a single week.
Second, I purchased a second 107G and it came as yellow. The 1st issue I noticed was the yellow 1, whilst completely identical other than color, was considerably way more powerful and battery lasted longer. As a result, it was much more enjoyable and alot more tricky to fly than red.
Third, getting that I am former active duty helocopter mechanic (CH-53a,d,e, T64-GE-416) for the Marines, I purchased the S108G (Cobra). Folks, the Cobra is a entirely unique helo all together. The collective (vertical manage) is not spring loaded like the S107G. Not only that, the Cobra is significantly even more robust in its response and power and can be tough 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 a single solid white light which I prefer to the flashing blue and red o the S107G. Mainly because the collective is not spring loaded you can make it hover and set the controls down on a table it nonetheless flies. At times I forget to return the collective to zero when I crash. The Cobra has lost reception a variety of occasions and when it does it falls from the air and crashes. The Cobra appears to "Pop and Click" like a Marine must--no kidding. It can speed around space substantially more quickly than the others and turns substantially a lot more speedily. In fact, the other appears sluggish in comparison and it is easy to "oversteer."
Forth, I also necessary to satisfy my curiousity connected to S109 (Apache). I have located the S109 is a lot easier than all to fly. It also has two white leds rather than the flashing blue and red of the S107G. The controller is the very same as the S107. General, I certainly discover it enjoyable to reliably fly around the room with complete and utter manage. I believe they did this to preserve the Army from crashing out of manage--just kidding solders!
Bottom line, I give the S109 leading rating more than the others. I do locate the responsivness and speed of the Cobra stimulating and of interest so I rate it second. If I fly with an individual else I will select the Cobra for its speed and responsivenees. In the finish, I don't believe the metal frame of the S107G will add a lot worth as the rest of the helo is plastic and does break. The cost of replacement parts can't be justified as a new S107G presently goes for 22$.
This helicopter flew very nicely - for a although.
Syma makes a number of quite slick little helicopters - I have bought several numerous models for the nephews and relatives, and every person loves them. This helicopter, the cobra, looks decent and flew extremely nicely. All of the Symas we tried so far fly extremely properly out of the box. The Blackhawk and Chinook flew rather well. The challenge with this specific (Cobra) helicopter is the landing gear. Immediately after a few crashes, the strut on 1 of the landing gear broke, meaning that on the ground, the helicopter will not stand up perfectly straight. No significant deal - ideal? Incorrect. If the helicopter is not standing up straight, it will not take off straight, and will in all probability crash into a thing prior to it stabilizes. The Blackhawk and Chinook have distinct landing gear which are extra durable.
For those of you who are initially time pilots, concentrate on hovering for your initially couple of flights. Just tweak the controls to attempt and preserve the helicopter in 1 place. If you can master hovering, the rest gets a lot less difficult.
Syma's mini helicopters are only for indoor use. The predicament with flying them outdoors is wind - the smallest puff of a breeze makes the helicpters uncontrolable.
For those of you who don't know a lot about Syma's RC helicopters, here is how they perform:
1. Stabilization: For real helicopters, the tail rotor controls rotation. Without a tail rotor, a genuine helicopter would be unable to turn, and would basically spin out of control. The motor for the main rotor desires to spin the fuselage in the opposite direction of the rotation of the primary propeller. Assume about it - if you were to magically "hold" the propeller in location, the fuselage would spin. The motor of a typical helicopter, if left unchecked, would spin the propeller and the fuselage in opposite directions. In genuine helicopters, the tail rotor counteracts the rotational force that the principal rotor applies to the fuselage
With Syma's helicopters (other than the Chinook), they truly have two primary propellers stacked on leading of every other that have blades that are angled differently, and spin in opposite directions. Both propellers offer down force, but also create torque on the fuselage in opposite directions. This has the effect of keeping the helicopter stable, because the rotational forces of the two propellers on the fuselage cancel every other out. Syma's remote controllers come with a "Trim" control knob. This control is applied to make sure that the 2 major propellers are spinning at the very same RPM. If your helicopter's fuselage spins slightly on takeoff, use the trim knob to correct it up.
two. Turning: In order to turn, Syma's helicopters slow down 1 of the main rotors by a compact amount, essentially employing the forces described in 1 to rotate the fuselage. Turning for all of Syma's helicopters is especially precise once you have them trimmed.
three. Forward/Backward motion - this is controlled by the horizontally aligned tail rotor. To go forward, the tail rotor spins, producing down force, which pushes the tail up. When the tail is up, the major rotors are angled slightly backwards, so the primary 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 do not have any mechanism for tilting the helicopter's roto sideways, so the helicopters have no ability to move side to side. In authentic helicopters, the main rotor tilts forward/backward, left and appropriate, and this gives the ability for the helicopter to move in pretty much 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 little as well responsive.
In brief, if you are a beneficial pilot, and will not crash, this helicopter is just fine. For my taste, even though, the Blackhawk and Chinook are way more durable and less complicated to fly.
1 other note - Very Necessary! This helicopter comes with an additional 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.
