An Ravenwing Attack Squadron constists of One Sergeant and 2 Bikers and can be upgraded with 3 extra Bikers.
The Squadron can have an Attack Bike and if it has 6 Bikes it can have a Land Speeder too.
Due to the CombatSquad rule the Squadron can split in 3 Bikes, 3 Bikes, Attack Bike and Land Speeder as individual Squads.
An Ravenwing Support Suqadron constist of 1-5 Land Speeders. One can be upgraded to a Typhoon and another to a Tornado. NO special rules are mentioned.
I quote myselfe

This composition is the reason behind my take on the Ravenwing.
Ravenwing Attack Squadron (effectively 2-4 Wh40k Squadrons)
8 Ravenwing Bikes.
up to 2 Bikes can be replaced with a Ravenwing Attack Bike each.
up to 2 Bikes can be replaced with a Ravenwing Land Speeder each.
So you could have
- 4 Bike Squadrons
- 3,5 Bike Squadrons with an AttackBike or Land Speeder
- 3 Bike Squadrons with 2 Attack Bikes, 2 Land Speeders or 1 Attack Bike with 1 Land Speeder.
- 2,5 Bike Squadrons and 2 Attack Bikes with 1 Land Speeder or 1 Attack Bike with 2 Land Speeders
- 2 Bike Squadons and 2 Attack Bikes and 2 Land Speeders
The Ravenwing Support Suquadron in essence is identical to the Land Speeder Detachment of the Codex list with the restriction that the formation can only have up to one Land Speeder Tornado and up to one Land Speeder Typhoon each.
But the wording odf this would be to wordy so i changed it that up to 2 Land Speeders can be upgraded to any variant. So you could have 2 Land Speeders Typhoon or 2 Land Speeders Tornado or a mix of them.
To make more of a difference i switched the Multi-meltas and Heavy Bolters on the Attack Bikes and Land Speeders.
Now the Land Speeders are a higly moveable mid-ranged fire platform and the Bikes are a pure assault formation with some FF-MW (from the Attack Bikes).
