4G3 double brushless helicopter

[ehirobo.com]

We receive a proto-type double brushless 4G3 from Walkera. As you can see from the picture it got different tail design, a fiber glass tail fin compare to the normal carbon rod. And the tail is a direct drive system which eliminate the issue with the pinion and spur gear spacing. The tail boom is slightly longer (4mm) compare to the orginal. And the tail drive system will work with existing 2605a receiver. The complete heli (without battery and canopy) weight 1.1g more than the single brushless version.

I had only do a short flight with it and I notice the rudder control is slightly faster than brushed version. And the tail hold quite well as will normal brushed version with new tail motor. Walkera said there maybe slight changes for production model as this one is a proto type.
