Let's start with the size, I guess. 30 ft tall, like a wooden juggernaut. They're like the wooden juggernaut but can fly, so I'd make them a bit lighter, like 15,000 lb? I'd be ok if you wanted to go with 20,000 lb like the wooden one and just say "magical flight" regarding the weight.
Hmm… I go for making it even lighter. Maybe 10,000 pounds?
If we assume the standard Wooden Juggernaut is built from something like Oak or Teak or Mahogany (which have densities of 0.6 to 0.9 kg per litre, call it 0.75 on average) and the Winged Juggernaut uses a lot more lighter materials like Bamboo (0.3 to 0.4 kg/litre) or lighter woods like White Pine, Redwood or Spruce (0.45 to 0.5 kg/litre) it could easily weigh a lot less, especially if it has a thinner, bird-like frame with larger hollow spaces.
Anyhow, how's this for a start:
An enormous statue in the shape of a winged humanoid with clawed hands and feet. It is cunningly fashioned from leather and wood with metal reinforcements at the stronger joints.
Winged juggernauts are a new variant of the wooden juggernaut that are almost always used to create guardian juggernauts (see the
guardian juggernaut template). They are relatively expensive and complicated to create, and the few communities that know the secret of their manufacture are reluctant to share them. Winged juggernauts may be far weaker than a true golem of the same size, but their ability to fly offers tactical options unavailable to most constructs.
A typical winged juggernaut stands 30 feet tall and weighs about 10,000 pounds.
COMBAT
These mindless constructs are incapable of developing tactics of their own, but fight according to whatever instructions their masters give them. They are often ordered to make dive attacks with their claws.

CONSTRUCTION
An enhanced winged guardian juggernaut is crafted from the same materials as the standard version. The materials must be of exceptional quality and cost 2,000 gp. An enhanced winged juggernaut with more than 4 Hit Dice can be created, but each additional Hit Die adds 1,000 gp to the market price. If this increases the size of the creature the price increases by 4,000 gp for a Gargantuan juggernaut and by an additional 7,000 gp for a Colossal one. The higher price includes the cost of the extra materials required to build a larger juggernaut, the total material cost is 4,000 gp for a Gargantuan winged juggernaut and 8,000 gp for a Colossal one.
