With a little reworking really good!

In the original state of the V911 is to use all right, but has some flaws which man with a little time and skill can easily fix. After I already have the 2nd V911 (BNF as a substitute), I can say that the main pinion "bent" is what causes vibration / shaking. However vague and there are some unforeseeable "dips" (compared to the optimized version) - However, the flight characteristics are also in this state within the framework. The quality of cabling is also not great and it should be fixed with hot glue, which also reduces vibration to a minimum.

Stability: Extremely (my now has more than 50 min crashes "without problems" survived.).
Handling: Suitable for beginners, but the first flights in the open air or in a very large room would be better.
Value for money: OK
Duration: moderate - 2 batteries are too little.
Accessories / Spare Parts: plenty available.

Here are my modifications:

- Fixed all cable with hot glue
- All stock / heads with graphite powder dry-lubricated (oil is a death sentence for such a mechanism -.. Max WD40 od ​​Balistol on the drive shaft!)
- Main pinion replaced by a performance replacement part. (Vibrations are noticeably less)
- 2 additional fiberglass struts between rear apron and motor mount to the stiffness, and thus enhance the precision. (Vibrations are noticeably less / reaction "brisk")
- Stick the transmitter with 2 VA screws by about 12mm extended (Increases precision / handling strong).
Fixed weights in the Flybar with superglue -
- Housing / Hood by reshaping the upper bracket tilted downward. (Otherwise, pushes the Flybar in violent maneuvers it on.)

Now there is a V911 "dragonfly" ^^ (but not the model at issue basically here ...)

Value for everyone else a try - for hobbyists a strong buy recommendation!
