Double Horse 9104 Video 

This is one of my latest helicopter goodies, the Double Horse 9104 3 channel, single rotor helicopter. IT's the first 3 channel with a working swashplate, and a standard, faces-sideways tail rotor. It is 100% authentic, and a very nice display model, too.  Single-rotor 3 channel copters always drift- the tail rotor is always moving them to the left, so you must compensate, and hovering is only possible against a slight wind.

This is the 9100 model noodling around here, I have them both. I found it to be a really fun trainer, and it also helps you gain more understanding of how a swashplate, flybar, and tail rotor work together. It actually increased my knowledge, as well as kept me busy adjusting for a few days.

S107 Tear-Down Video 

This video shows a Syma 3 channel helicopter being torn apart for no reason other than to show the sequence in which it comes apart. I have many of the small copters by Syma, and they usually do not have to be worked on. 

But if your copter needs a tweak or a repair, it may look like a hopeless pile of parts if you get ahead of yourself. NOTE, that all parts are bagged and tagged upon removal, with their srews. Most copters have as many as five DIFFERENT SCREWS holding them together. Be sure they get back in the locations they came from on the 3 channel helicopter, as you put it back together.
