Client Critiques
I personal 4 SYMA helos and they all have different characteristics.
1st, I bought a red S107G for 22$ and was blown away. But, immediately after a multitude of crashes connected to hitting the ceiling my initial a single 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 initial thing I noticed was the yellow 1, whilst totally identical other than color, was a lot a lot more potent and battery lasted longer. As a result, it was much more fun and way more hard 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). People, the Cobra is a fully numerous helo all together. The collective (vertical manage) is not spring loaded like the S107G. Not only that, the Cobra is considerably additional 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 entirely plastic (as apposed to the S107 having a metal frame). Also, the Cobra has a single solid white light which I prefer 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. Oftentimes I forget to return the collective to zero when I crash. The Cobra has lost reception a few times and when it does it falls from the air and crashes. The Cobra appears to "Pop and Click" like a Marine will need to--no kidding. It can speed about space much more quickly than the other people and turns a lot much more speedily. In reality, the other seems sluggish in comparison and it is straightforward to "oversteer."
Forth, I also required to satisfy my curiousity associated to S109 (Apache). I have located the S109 is less difficult 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. Overall, I extremely get it enjoyable to reliably fly about the room with total and utter control. I think they did this to maintain the Army from crashing out of control--just kidding solders!
Bottom line, I give the S109 top rating over the others. I do find the responsivness and speed of the Cobra stimulating and of interest so I rate it second. If I fly with somebody else I will select the Cobra for its speed and responsivenees. In the finish, I don't assume the metal frame of the S107G will add much 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 really well - for a while.
Syma makes a number of quite slick tiny helicopters - I have purchased quite a few different models for the nephews and relatives, and every person loves them. This helicopter, the cobra, looks great and flew incredibly nicely. All of the Symas we tried so far fly very nicely out of the box. The Blackhawk and Chinook flew fairly well. The challenge with this particular (Cobra) helicopter is the landing gear. After a few crashes, the strut on 1 of the landing gear broke, meaning that on the ground, the helicopter won't stand up perfectly straight. No significant deal - right? Wrong. If the helicopter is not standing up straight, it won't take off straight, and will possibly crash into a thing before it stabilizes. The Blackhawk and Chinook have several landing gear which are a lot more durable.
For those of you who are 1st time pilots, focus on hovering for your 1st few flights. Just tweak the controls to try and keep the helicopter in 1 spot. If you can master hovering, the rest gets a lot simpler.
Syma's mini helicopters are only for indoor use. The dilemma with flying them outdoors is wind - the smallest puff of a breeze makes the helicpters uncontrolable.
For those of you who do not know significantly about Syma's RC helicopters, here is how they function:
1. Stabilization: For true helicopters, the tail rotor controls rotation. With no a tail rotor, a genuine helicopter would be unable to turn, and would essentially spin out of manage. The motor for the main rotor wants to spin the fuselage in the opposite direction of the rotation of the primary propeller. Consider about it - if you had been to magically "hold" the propeller in place, 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 most important rotor applies to the fuselage
With Syma's helicopters (other than the Chinook), they essentially have 2 most important propellers stacked on top of every single other that have blades that are angled differently, and spin in opposite directions. Each propellers produce down force, but also create torque on the fuselage in opposite directions. This has the impact of keeping the helicopter stable, because the rotational forces of the two propellers on the fuselage cancel each other out. Syma's remote controllers come with a "Trim" control knob. This manage is applied to make confident that the 2 primary propellers are spinning at the similar 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 one particular of the main rotors by a small amount, basically applying the forces described in 1 to rotate the fuselage. Turning for all of Syma's helicopters is really 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 main rotors are angled slightly backwards, so the principal rotor pushes the helicopter forward. Reverse has the opposite effect. The tail prop pushes the tail down, which angles the thrust of the principal 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 potential to move side to side. In genuine helicopters, the primary rotor tilts forward/backward, left and appropriate, and this gives the ability 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 appears like the helicopter is a tiny also responsive.
In brief, if you are a great pilot, and won't crash, this helicopter is just fine. For my taste, even though, the Blackhawk and Chinook are much more durable and easier to fly.
One other note - Really Crucial! This helicopter comes with an further tail rotor in a plastic baggie. Save it, and put it in a secure place. The tail rotor controls forward and backward motion, and if you shed your tail prop, all you can do is hover.
