More to the point... Does anyone know what the official Syma web page or online catalog is? I'd like to know whether these white/green options are legit or not. Sorry if I just haven't found it yet--assuming it's buried deep in these forums.
Try http://www.symatoys.com The new style canopy shows on the home page, but not on the S107G product page, (probably just not updated yet).

I've seen Green:

and White:

S107Gs now. Are these legit or are they clones? Where is the *official* SYMA web page? Anybody know? Is this it?

http://www.symatoys.com/product/show/1830.html

I've also seen these from an Amazon reseller called Halley R Us:

http://www.amazon.com/White-Channel-.../dp/B006BLK9L2

http://www.amazon.com/Green-Channel-...dp/B006BLJKEY/

who has a LOT of interesting alternative parts for the S107G like the Helizone RC Firebird canopy, blades, and tail decorations:

in black : http://www.amazon.com/gp/product/B005TC8HWC
and blue : http://www.amazon.com/gp/product/B005TC8UKQ
Clones or the real deal?!?! Either way, IMHO I don't see any bargain prices. Just my 2 pennies worth.

Well, I had burned out the tail motor on my red syma S107g clone. Well, felt pretty good this afternoon and decided to install the new part I got in the mail..the whole tail boom and motor. Had to tear apart the heli down to the PCB. Desoldered the on wires unscrewed the boom and removed it...install the new boom carefully routing the wires, and carefully soldering the wires to the board. Put everything back together and it flys great!!! Can't believe I didn't screw something up.....did have to use a different rotor blade as the syma motor turns opposite the clone motor...!!

Motor turns in opposite direction??? Jake, while you were doing all that soldering work, it would have been the perfect opportunity for you to reverse the motor wires!!!

Tried the 4-bladed tail rotor on one of my S107s... easy to do, the motor shaft pushes right through the standard rotor, and the second one can be pushed on that, with a small drop of CA.
Didn't any noticeable difference in forward or backward speed.

I found out something very interesting...I fudged up one of the upper blades. Took one out and put on and had the most horrible shakes. Looked at the bades. One upper said 'A' on the blade and the other said 'A1'. Took the A1 off and put on an A and no more shakes...must be a difference between A1 and A blades..same with B1 and B blades I am guessing...learn something new everyday!

That is interesting Jake. I just looked at mine. My "original" #1 S107 top blades are marked "A2". My second S107 top blades are marked "1A." Almost wants to make me remove and weigh each one of them up for the sh **ts of it.

After Christmas

Mike.

Mine:
S107-top blades have "3" on them. Bottom blades have "2" on them.
Mini Chinook-top blades "A1". Bottom blades "B1".
Anyone else?
Tell us your blade i.d.

Yeah Jim, this is a pretty interesting subject Jake brought up. I'll be recording the stamp# and weight of the top and bottom blades. I assume the two S107's I have are genuine.

But, Like I said...after Christmas

Merry Christmas everyone

Mike.

A few months ago, I noticed something very similar with the blades of my U807:

The discussion in the U807 thread did not really settle, maybe you guys will be able to do some conclusive tests on your S107 blades.

Note that you can also get rid of some vibrations by weigh balancing the rotors with Blu-Tack:

Replacement Blades

I've noticed the difference in blades a while back. Like there is real and fake S107s, there is real and fake replacement blades also. Again, know your sellers, so that you don't buy fake ones.

So far, I have seen 3 different grades of blades. What I considered the real, top tier, best quality blades have either "A1" or "1A" stamped on the upper blades, and "B2" or "2B" stamped on the lower blades. These blades are the thickest, and the heaviest. With all the flights I have with my trainer S107, which I give to first-time flyers to fly, it is still on its original set of the blades.

Next group, the upper blades have "3" stamped on them, and the lower blades have "4" stamped on them. I found these as close seconds to the top tier. I do find these shipped with some genuine S107. I consider them as cost-reduction blades from Syma. They are just slightly lighter, thinner, and their colors is slightly off white, sometimes. In general, I don't have issues with these. But you don't want to mix them with the A's and B's, because they are slightly different.

Last group, usually found on fake S107 or sold as replacements from less reputable sellers. They don't have any letter or numbers of them. They are significantly thinner and lighter, and they break easily. So much so, you will notice the difference by feel when you have one real blade in one hand and a fake one in the other.

Take a look at the photos below. The real SYMA blade (B2) is 1.25g and the fake one is 1.10g. That's more than 10% off! Believe it or not, I received these as part of a set!! Needless to say, I won't use that seller again.

Of course it's best to get the top grade replacements. But if you get the middle grade, or even the lowest grade replacements, it's not the end of the world. Make sure you use the matching ones, and replace them as a pair. Don't mix in blades from different grades, because they would be out of balance.

OK...this thread is too freaking long!!!

I am trying to find info on modding this heli to accept a Turnigy 160mah lipo. I don't own the heli yet but want to make sure it's going to be easy to do if I buy it. Wouldn't that enable me to spend more time in the air - if I could run for 5 minutes then just swap out for a fully charged battery?

Otherwise, I need to look for a stock heli that accepts the 160mah. I have 10 of them on hand.


I know several of you have done it...but is there a write up somewhere I could review? Or can anyone tell me if it's easy/worth it?

I'm with you there...
I'm new to this stuff also but like you, I like the idea of using the Turnigy 160mah lipo. There is a mod elsewhere, I'm leaving right now or I'd point you to it. If you are handy with electronics you will be able to run with it (I'm not). I'm trying to combine the idea of adding the circuity protection board (found on the stock battery) to a newly modified charger... which would then allow for the use of an unmodified Turnigy 160mah.
It's kinda using the ideas of 2 different mods I've found here and elsewhere.
