Well, here it is.. looks a bit better than the last version and runs so SMOOTH.

It uses the Lama V3 frame, a mix of Esky and Xtreme alu parts (all Esky in the picture), the Extreme canopy, tail and landing skids, 2 outrunner BL motors, 2 10A ESC, 2 fast digital servos, the E-sky 0704 gyro (while waiting for the 0704A) and a spektrum 6100 receiver. Weight without LiPo is 190g.

It works well on both 7.4 and 11.1 V Lipos - achieving an incredible 660g lift on 11.1V 20C battery.

Flying on a 7.4V is like flaying a normal Lama - just more precise and faster. On 11.1V, it takes off on 1/3 throttle and can shoot up vertically very fast.

Fitting the 18mm diameter brushless motors was a bit of a challenge - they are 1 to 2mm too big to fit comfortably. My 12mm ones are here but I dont have the pinions yet.

Getting better responsiveness with increased power was also a bit of a challenge - and is still pretty much WIP - although some of the tweaks really do help.

I still need to try it outside with decent winds. I expect it to drop a bit when the gyro reduces speed to compensate the rotation, as the gyro is only linked to one rotor.

OK, enough for now.. time to play!

Thanks for posting this. I have been looking for a way to take my Lama 4 brushless.
Where did you purchase your gyro and motors?
