It is my Japan version seahawk and fly with DJI system ,the first some second is me manual control , after in air high level, switing to full auto , it is very safty and never same this (safty feel in a 4 blades head and scale heli) . the feeling is wonderful .i can put more money in the heli in big big size . and than i have keep the full auto and down the power , it come down in same position till it touch the ground ,but the front title angle let the fuselage go frontward , it mean this frontward moving let it super scale in taxy !much fun !

Tested two tail servos, BLS251 and S9254 typical for tail.

Lower BLS251 down to 333, S9254 to 165hz. Not much difference in performance.

After more than 4 weeks trying to isolate the vibration .... longer shaft to shorter main shaft, bracing after bracing from frame to fuse, balancing re-balancing main blades. Finally a new pair of blades resolve the issue. Next came tail holding, motor driven tail rotor system is easy on elevated tail but tuning it is another story, at least for me. It still needs some more tuning, but I am happy it gets off the ground. Will tidy up the wiring and GPS.

this looks very intriguing, hopefully it won't be priced in the stupid realm.

MSRP should be less than half of the Ace One. In two more weeks we will know for sure.

So $1750? Auto take-off/land, GPS hold, coax-type of flight options, but no waypoint stuff?

I gotta say, it sure flys smooth
