The GYRO mod works.

The Gyroscope mod: This advanced mod allow the R5 board to be able to turn a LOT faster than normal (or the R3, and still be perfectly stable).

By using something known as a voltage divider,we can reduce the sensitivity of the output on the gyroscope.

Using a 10k potentiometer, I am able to easily adjust the turning speed/sensitivity from 100% all of the way to 0%

Potentiometer glued to underbelly of helicopter for quick adjustment.

However this mod requires very fine hand movement to solder onto the there is very little area to solder to on the board (~1mm x ~2mm), so may be very difficult to accomplish.

Here are some pics of the chanel reverse mod, It allows the Silverlit propellers to be used without flipping the tail over.

Edit:does anybody know how to make the images work, without everyone having to resize them when they want to look at them?

Edit: FIXED (hopefully) 😛

I've done the primary thing with that where you flip the rotor, and I think it's a really effective way to speed it up. It allows the blade to accidentally take more damage at some times when close to the ground, but protects it when up in the air. It also helps keep the blade on the shaft, and I think it gives it a more lift at full speed. (although thinking into it, there isn't a real scientific backing on that, but it seems like it helps give it some more speed even if it had the stock blade)

Man, keep up the great work, that's a lot more than what any of the rest of us are willing to spend on these things! Just about everything you've done so-far is all stuff that wll of us either thought impossable, or at least impossable for amatures like us to do.

This time its another mod, on the battery.

This simple patch allows the battery charger port to have direct access to the battery without the diode, at all times.

The reasoning behind this mod, is the safety features on the charger socket are causing me problems when trying to use the discharge function on my balance charger.

I also decided that I would like to still access the battery once the helicopter is turned ON. As a result of this i can now have the potential to piggyback a removable battery into the socket, or use it to power a removable 3v external device, etc.

Hopefully some fun stuff can be made as a result of this simple mod

Edit: This works great with my balance charger, I did a full discharge cycle, and have recharged with the balance charger. Now it is returning a more realistic battery capacity of 156mAh, shame it takes about 1 and a half hours to charge at 100mah though.

However it did get just over 6minutes of (constant movement) flight without any other mods.

Raptor,

Yep the SKYRC  "laser sticker" is there and the QC pass thing is there to.

I ordered it from Hobby King so should be ok.

BTW CPD I only payed £29 As for UK £80 + so not worried if it is fake, if it is well the bin is next to me.

Sounds like my kind of luck there, SN! Hopefully yours will be a good, solid charger worth the insane price you paid for it.

By the same token, if you think about it, most people'd say that s107's are mostly all fakes or clones too.

Here's another mod of sorts.

I'm always cautious when it comes to Li-po's, as I've had a few problems with them in the past, and now I'm slightly paranoid around them

The electronics inside the USB charger, on examination are really basic. So i decided on finding a alternative (safer?) way of charging. Using what I had on hand, the chargers I've adapted to be capable of charging the S107 are:

A Ultrafire WF-139 or WF-188 - this gives a nice 300ma fast charge, and also a basic LED that indicates that its fully charged, capable of charging two helicopters at once, and seems to be safe if left on for longer than needed.

A Lipo Balace charger - These are fantastic chargers, they can charge almost ANY battery you through at them (Li-po, Li-ion, Li-Fe, NiMh, Nicd, SLA), they have a LCD screen that tells you how many mAh your battery has taken  and a audible alarm that it has fully charged. Theoretically capable of charging up to 6 helicopters at once.

However this type of charger has gone the same way as the S107 itself, and there are so many clones you cant tell which one is a original. I highly recommend >this<. AVOID iMAX at all costs, they are mostly Clones, OF A CLONE, as I found out the hard way 

I found this on youtube a while ago, I tried it myself and couldn't believe that it worked 😛

Thanks, I hope that you find the mod useful . And I'm not bothered about credit, I just want to help people get more fun out of their stuff.

Before you do the mod, just try controlling the helicopter when there is no cover on the transmitter, essential you will get the same effect on handling.

Thanks for the very nice video i've done the spring removal on the throttle, and have been wondering how to increase the resistance on the stick, that's a ingenious way to resolve it.

However, I was referring to the stick on the right, with the circular hole. If you file it square it seems to increases the maneuverability of the helicopter whilst at full speed.
