Anyone, what am I doing wrong. I mounted 3x TGY-930 servo's for the swashplate. When the arms are 90 degr to the control arms going up to the swash, then the blades are way down in positiv (lift up) position, while they also should be in flat neutral position. I checked the lenght of the control arms (D) with the Align Trex-500GF manual, and they allmost correct. Is the Main Shaft too short or so.? I cannot figure out what's wrong here.. TIA and cheers, JeffBr.

Umbrella gears in tail boom holder bind, frame is slightly twisted. The canopy was cracked on arrival. You know the more HK stuff I buy the more I think I should just spend the extra and go top name brand.

i have had mine for 2 months now and i love it. i was struggling to hover my blade 400 but this machine virtually flies itself. my main gear was a little warped but replaced it with a new align one and it is perfect now. in nil wind conditions it will hover hands free for at least 6 secs before you have to add some input to keep it on the spot great chopper HK i love it.i fly mine on a turnigy 4000 25c nano battery and i can hover and general flight for at least 8 mins thanks HK

I have had mine for about a month now. It's had about 30 flights, no crashes.It fly's great. All my previous experiance is with 450" and smaller. t-rex furion etc.Only changes that I MADE WERE OUT OF NECCESSITY. talrotor blade grips to metal, blade bot let go during spin up 8th flight. Flybar leavers and swash plate levers to head, replaced for metal. plastic ons flexed to much, could not get blades to track. Otherwise stock hk all the way. hk motor servos, and gyro all works great. had about $ 225 U.S. dollars total. less radio and battery. maddog

Bought this kit arrived today 7 days shipping to New Zealand vis Air Mail so aint bad. Arriived well packed nothing broken no missing parts.
I read all the reviews on this kit here and in my mind was 50/50 good and bad comments some saying kit total waste of money etc etc, but thought what the hell 1/4 the price of Align.
Put the kit together and must say I am very happy with it if I was moan about something it would be the rubber gromits that are fitted to the canopy they broke after taking the canopy off a couple of times so will get 2 from work and will make the holes a bit bigger no big deal.
Will get it in the air and comment on the flight.
Other than that can't fault it for the money!! Thanks Hobbyking
