Double Horse 9117 4-CH 2.4G RC Helicopter Review

When I received my Double Horse 9117, some comparison with 9116 inevitably struck my mind and that was the lesser substantiality of the younger brother. Particularly mainshaft and swashplate seem to be smaller than how they should be looking at the size of the heli. I realized some interesting points about this 4-channel 2.4G heli with gyro…

Comparison with 9116

This is much bigger than the elder bro, can be called a 300 class, though not 450.

Transmitter is same as 9116, so I wonder only 1 of can be used for both, with some changes in the trim. I want to see if this one can fly on zero subtrim like my 9116.  


Servo wires keep messing with the shaft as they are not bunched up. So I had to do that first. Even the main shaft is too shaky, so I had to change the collar setting. Screws are loose.

The cheap charger takes a real l-o-o-o-n-g time to charge the battery fully – 3 and half hours! And when I charged the other battery with an Imax B6 – it took just 50 minutes!

Spare Parts Availability

I must say spare parts availability of Double Horse is great. But here there is one catch, that 9104 parts can be excellently used on 9117!


When I first tried to see if everything is well, the motor seemed not so powerful to handle that big heli. So, I was interested to see how this one flies outdoors. And I must say I got a good experience because it is quite easy to fly and I think no experience is needed for this one. But there was no wind – so I must further try on a windy day. It is good that they have provided extra battery. One battery can never be sufficient as gyro cannot provide enough extra power.


DH9117 is good for learners for that price. But if you are an expert, you need not invest in this heli. Better do it in 9116 or even 9104.
