It is a clone T450 belt drive stretched to a 500 in an old gen. 1 SM/TF 500 size EC-145 fuselage.
The airframe as I said is a modified T450 clone with a delrin cnc cut main gear, Scorpion HK-2221-10 (3000Kv) motor ( thanks to SidewaysLS4 ) , a Turnigy dlux 55A ESC , highly modified CopterX ridgid 4-bladed head , Carbon Hobby 425mm main blades , cut down (80mm) mCPX main blades on the tail , HD-1810MG servos ( cyclic ) , and HD-3688HB (tail) , and a Tarot ZYX FBL unit.
She runs a HS of 1540 with my Blade 400 tail speed up mod which give me a 1:5 tail ratio , this gives her plenty of tail authority along with the cut down 80mm mCPX mains on the tail.
Her AUW with two 4000mah 3s packs on board ( for correct CG only , it runs on 1 pack at a time ) is right at 5.75 lbs and she flies for 8:30 - 9:15 minutes per pack and like a dream too.
Enjoy the pics and feel free to comment or ask any questions you might have about it.
Great looking heli,
You have two packs onboard, why not connect both in parallel. This would give you an 8000mah set at 3S and could almost double your flight time. Since the extra pack is already onboard.... I do this for my 500 size Jayhawk, of course with two 6s packs..
