so this helicopter can lift wireless camera 20 grams and 9v battery 30 grams for camera

totaly 50 grams?

@TheDonis88 Yes, it should lift 50 grams.

Aren't you slashing your flight time by adding all this weight? SERIOUSLY - do you think adding 18 grams to your flight weight doesn't hurt your flying time? You'd be SO much better off with a slightly heavier, higher output battery!

[hammydude12345]

@seq165432 You're right, any time you add weight the flight time is decreased. Adding 14 grams to the canopy is a 3% increase in weight, this would reduce an 8 min flight time by about 17 seconds. Please note that I recommend using a higher output battery and moving it forward.

@hammydude12345 The canopy on my S107 weighs 2.5 grams, so I took it off. I removed the tail fin too. A section of soda straw holds the LED as far as the wire will go, so it has what looks a bit like a refueling probe - holding the LED and a little piece of metal it's attached to as far forward as possible cancels out the unbalance of no canopy. It looks weird but flies a bit longer. Hopefully, replacing 240 mh battery will extend it even more.

@seq165432  Sounds good!

@hellonblades For some reason Double Horse doesn't make helis that travel with any speed. Out of the box my 9104 wouldn't fly forward at all. Try adding some weight to the canopy, and adjust the swash plate so it tilts forward. Then if you want more speed lengthen the servo arm. Good luck.

How did you get this helicopter from not flying in that drifting circular motion that these heli's tend to have? It"s really annoying. Doe's it have to do with the swash plate, or is it a unbalanced weight issue? I can't get mine to fly straight. It does nothing but circles. What do you suggest?
