Could use more spare screws
on August 9, 2016
These parts are accurate replacements for the Syma S107. However, a word of caution: If you, like me, have the WorldTechToys version of this helicopter, the main shaft won't fit. On the WorldTechToys version, the shaft is slightly thicker than the shaft that ships with this kit.
I bought this kit because the piece that secures the top rotors to the main shaft broke, causing the "Toilet Bowl Effect" unstable flight. The issue is described in a video I found on YouTube. It seems that the two pins on the main shaft mount that allow the blades to pivot are easy to snap off, and the shaft mount needs to be replaced.
However, the replacement top rotor mount would not fit on my main shaft. I tried drilling it out, but then it was too loose. So in the end I just chucked the helicopter, since it would be cheaper/easier to get a new Syma at this point.
None of this is the fault of this replacement part kit, however, just a word to the wise.
I took one star off because the parts kit is somewhat incomplete:
- It does not include the screws that attach the counterweight to the top rotor. Extra screws would be appreciated since these screws are so tiny
- It includes the t-shaped main shaft mount, but not the rotating piece that attaches the blades to the t-shaped mount, nor the piece that attaches the lower rotors to the counter-spin shaft I had to re-use these from my old helicopter.
Everything you see in the pictures is what you get, so make sure you have enough left of your original helicopter to cannibalize parts.
