Its appearance and function in some regards seems to take inspiration from a HIND attack helicopter. Note, double cockpit, one for pilot and one for gunner. Normally with "chin" mounted gun and capacity for carrying a squad. Among helicopters it is pretty sturdy (Capable of taking small arms fire with ease) and returning fire with devastating results. I don't think the top speed of the Valkrie is currently where it aught to be. Heck, the outer engines aren't even animating. But given that this seems to be their point of inspiration, the design, the degree of yaw, the control in hover mode, crew capacity and forward gun; We might see some other elements associated with it. Namely resistance to small arms (more than an ESF) and a more powerful cruise mode.
