Hi ,

 

New S107G owner here ūüôā , wife bought it as an¬†anniversary¬†present for me this weekend.

I have been flying it a couple of times a day since I've had it and one thing I notice is ,  that whilst hovering , it tends to drift backwards in an arc.  

Is this normal for the S107G ? or is there a way of correcting this ??

 

Many Thanks

 

Diz

Diz,

     I have the same problem--except my bird slews (or drifts) sideways.  If I put enough artificial weight on the opposite side landing struts I can stop the annoying behavior.  However, that seems unnecessarily inefficient. Surely, there is some type of trim mods that will cure both our problems.    REB

@REB There is a trim button on the remote-have you tried that yet?

Yes I have,

     That adjustment controls the helicopter's tendency to rotate through its center of lift--the main shaft.  My problem is the craft's characteristic to fly sideways,  nose pointed to 12 o'clock flight path drifting toward         9 o'clock.  In a full size aircraft this is done by tilting the rotor disk in the desired direction, the pilot looks straight ahead (12 o'clock), but the aircraft moves toward his nine (Left). Since the Syma has no cyclic control, the issue has to be trim or perhaps a bent main shaft.

@REB Always difficult to pin down problem without flying the bird myself-however crashes cause most of the problems-Things to look at-are-gears meshing ok no teeth missing,main shaft could be bent,check rotor screws all tight,check rotor blades not split,take off canopy two screw check battery not fitted properly can change cig (center of gravity)

There is a video put here on what they call TBA- Mostly if lifting ok you might check rear tail motor shaft is aligned ok-I have heaps of helis and planes-patience and sitting down going through the faults things you will see-took me a week to find why a glider plane would just not fly-I had attached the motor wiring wrong and motor going backwards not forward-stupid me-always a learning curve-keep us posted here Confused

Kudos for your input.

      You're right of course, the odd collision with immovable objects has taken a toll on the vertical parts of the helicopter.  The main shaft is tweeked and I suppose I must replace it.  The video you linked to is worth a couple new aircraft---a new set of screwdrivers and I'm ready to learn.   

          Again, thanks for your time,  RB

@REB-you could try with two pliers to straighten main shaft-do not squeeze to hard as hollow-if you screw up guess you will need to buy a main shaft-or keep as spares and just buy a syma S107 without remoteCool

@REB The simple things can work-when you get any problems with helis or planes you have to think it out-you have done that-from now on you begin to learn more on flying mini helis-as you progress and you will to 5 channel helis you will be thankful of your learning curve with the Syma S107-Well done Laugh

Many thanks for the encouragement,

     Since it appears that the "whole" is less costly than the sum of its (repair) parts, I would like to consider purchasing two or three 107G's and using the the current bird for parts.  However one can only use so many controllers (I have two) and would like to know if and where the helicopter can be reliably bought bare---without the IR transmitter?

@Reb to be honest the only place I know at present to buy a Syma S107 without a remote is RcFever
