The heli arrives in a BIG brown box containing at least 50% air - most of the volume is takenb up by the canopy box - a rugged, GF affair with the famous F3C pectorals and air vents. THe smaller parts box has an x-ray view of the Impaction on the front and opening up reveals glistening gold anodisation offset by sexy black highlights - gorgeous metalwork !

The boom is CF - odd size 25.5mm diameter and the tail is belt driven. The rotor head comes ready assembled and is the F3C version with flybar and associated gear. The struts are super low profile and the frames are glossy high quality 2mm black CF.

Perusal of the guts reveals a two stage drive train - motor pulley via belt to intermediate shaft which gears with a composite alloy/Delrin main gear. Not knowing which motor I would be running I elected to buy a six pack of pulleys from Funtech to accommodate motors from 450-560kV and maybe 12-14S.

I think I may put in my sbus servos in this heli to aid with precise, no-subtrim setup and initially plump for the Pyro 700-450 with HJ 120HV on 12S or maybe even give 14S a go !~

THere's a nice Build Thread for the Impaction on ARCHeli and Cygnet's beautiful Impaction in Staysee II fuze is shown above
