Customer Reviews
I own four SYMA helos and they all have completely different characteristics.
Initially, I bought a red S107G for 22$ and was blown away. Even so, just after a multitude of crashes connected to hitting the ceiling my initial one was starting to show wear (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 bought a second 107G and it came as yellow. The initial issue I noticed was the yellow one, while absolutely identical other than color, was considerably much more powerful and battery lasted longer. As a result, it was additional entertaining and even more tough 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 fully unique helo all together. The collective (vertical manage) is not spring loaded like the S107G. Not only that, the Cobra is much way more robust in its response and power and can be complicated to manage. This is troublesome to me as the Cobra's body and frame appears to be absolutely plastic (as apposed to the S107 having a metal frame). Also, the Cobra has one solid white light which I favor to the flashing blue and red o the S107G. Simply because the collective is not spring loaded you can make it hover and set the controls down on a table it still flies. Typically I forget to return the collective to zero when I crash. The Cobra has lost reception several instances and when it does it falls from the air and crashes. The Cobra appears to "Pop and Click" like a Marine should--no kidding. It can speed around space considerably faster than the other individuals and turns much much more easily. In fact, the other appears sluggish in comparison and it is uncomplicated to "oversteer."
Forth, I also needed to satisfy my curiousity associated to S109 (Apache). I have identified 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 really uncover it enjoyable to reliably fly about the room with complete and utter manage. I assume they did this to preserve the Army from crashing out of manage--just kidding solders!
Bottom line, I give the S109 top rating more than the other people. I do get the responsivness and speed of the Cobra stimulating and of interest so I rate it second. If I fly with someone else I will pick the Cobra for its speed and responsivenees. In the finish, I do not consider the metal frame of the S107G will add a lot value as the rest of the helo is plastic and does break. The cost of replacement components can't be justified as a new S107G presently goes for 22$.
This helicopter flew quite nicely - for a while.
Syma tends to make a quantity of incredibly slick small helicopters - I have purchased quite a few unique models for the nephews and relatives, and absolutely everyone loves them. This helicopter, the cobra, looks fantastic and flew fairly properly. All of the Symas we tried so far fly really nicely out of the box. The Blackhawk and Chinook flew fairly nicely. The challenge with this distinct (Cobra) helicopter is the landing gear. After a handful 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 massive deal - right? Wrong. If the helicopter isn't standing up straight, it will not take off straight, and will in all probability crash into some thing just before it stabilizes. The Blackhawk and Chinook have various landing gear which are much more durable.
For those of you who are 1st time pilots, focus on hovering for your initial handful of flights. Just tweak the controls to attempt and preserve the helicopter in 1 location. 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 tends to make the helicpters uncontrolable.
For those of you who don't know a lot about Syma's RC helicopters, right here is how they operate:
1. Stabilization: For authentic helicopters, the tail rotor controls rotation. Without having a tail rotor, a true helicopter would be unable to turn, and would actually spin out of manage. The motor for the most important rotor wants to spin the fuselage in the opposite direction of the rotation of the major propeller. Believe about it - if you were to magically "hold" the propeller in location, the fuselage would spin. The motor of a usual helicopter, if left unchecked, would spin the propeller and the fuselage in opposite directions. In authentic 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 in fact have two primary propellers stacked on top rated of every single other that have blades that are angled differently, and spin in opposite directions. Both propellers give down force, but also generate torque on the fuselage in opposite directions. This has the effect of keeping the helicopter stable, considering that the rotational forces of the 2 propellers on the fuselage cancel each and every other out. Syma's remote controllers come with a "Trim" manage knob. This control is made use of to make certain that the 2 primary propellers are spinning at the exact same RPM. If your helicopter's fuselage spins slightly on takeoff, use the trim knob to true it up.
2. Turning: In order to turn, Syma's helicopters slow down 1 of the most important rotors by a tiny quantity, essentially employing the forces described in 1 to rotate the fuselage. Turning for all of Syma's helicopters is especially precise when you have them trimmed.
3. 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 most important rotors are angled slightly backwards, so the main rotor pushes the helicopter forward. Reverse has the opposite effect. The tail prop pushes the tail down, which angles the thrust of the main 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 capability to move side to side. In genuine helicopters, the principal rotor tilts forward/backward, left and appropriate, and this provides the capability for the helicopter to move in pretty substantially any direction.
This Cobra heli is not as stable in flight as the Chinook or the Blackhawk. It just seems like the helicopter is a small too responsive.
In brief, if you are a fine pilot, and will not crash, this helicopter is just fine. For my taste, though, the Blackhawk and Chinook are even more durable and much easier to fly.
A single other note - Really Valuable! This helicopter comes with an further tail rotor in a plastic baggie. Save it, and put it in a secure location. The tail rotor controls forward and backward motion, and if you shed your tail prop, all you can do is hover.
