Default 4G3 double brushless helicopter

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.

Well it's about time!

Why didn't they release the BL version as a full BL, rather than just a BL main with the weak brushed tail motor I can't understand. Unfortunately I' ve already made a modification to my 4g3 with a 2.9g BL outrunner on the tail, the brushed tail would "blow-out" while in Idle-upif large collective inputs were made. The BL tail holdsway better, althoughthe gyrowill cause tail wag at times.

Is the dual brushless 4g3 really coming out on the 31st or is it actually coming out later?  It says the 31st on your site.

I do find the same thing happen with the prototype as it hold quite well. But the tail wag from time to time. But as I only have 1 short flight with it I am sorry I really can't say much about the performance. But with our pass experience with walkera prototype it is highly possible they may change small detail for the production model. BTW: It should be out very soon and we got the 4#3b double brushless prototype as well. Will post some picture later today.
