I am not sure of the overall effectiveness of the razorwings? I have not used flyers yet but I plan on purchasing 2. The Internet has a sort of love hate relationship with them.

I've had good experiences with Razorwings for the most part. I would however make points available for the spirit probe on the cronos. A good place to start would be dropping the cannons on the jets. After you drop the missiles, their main use should be anti-air/anti-mech, unless you know you're going to be playin Nids then by all means keep the cannons.

I like your list a lot. Specific load outs for your heamonculus are a personal preference. They look fine. Also, I'm a fan of chain flais instead of the ichor, again personal preference. I alsp loke that 4+ the chronos gives.
I always run my razorwing with both lances and splinter cannons to help with flying MCs. I play against Tyranids a lot so it helps. Also, I would keep at least 2 of the ravagers as is and consider making the third with all dissy cannons

I do have a spirit probe on the cronos. I think I just wrote that in wrong. I was running dissengrators with a splinter cannon on the razorwings. What do you think is the preferred setup. I also figured in my meta my haemonculus will get torn to pieces in challenges so there is really no use in me gearing him out to get hammered.

How about the vexator mask? Should help. Dissys on razorwings work well against MCs too, I misread your original post.

My warlord is going to be the dark artisan Haemonculus I figured the pain engines would do the heavy lifting.

A scissorhand on the Haemy is pretty good for any target you get stuck in with what with the rending being able to help break vehicles. Having the DA haemy as the WL is also a good idea since he will allow the squad to re-roll FnP rolls of 1. Having 2xDL on the Razorwings is the usual load out, mainly to deal with enemy flyers. I'm a bit confused, the Kabalite detachment is that an ally/CAD/RSR detachment?

Combined arms detachment

The real space raiders are the main detachment with coven formations as allies I suppose.

Someone please correct me if I'm wrong, but if that's the case then the DA Haemy wouldn't be able to be the warlord. I think that the warlord has to be from your primary detachment, which would be from the RSR detachment.

I was told that any HQ can be the warlord. If so how would I go about making my coven haemonculus the Warlord.

Again, I could be wrong as I don't have my BRB in front of me, but if its legal to have the RSR detachment as an ally without having to follow the "allied" detachment guidelines, I think you would then be able the have the DA haemy be the WL.

How would I go about reorganizing the list to make him the warlord.

You don't have to do much. I think you can just declare that the DA is your primary detachment and thus that haemy is going to be the WL.

Great, I was also considering shifting some points around to put agonisers on my aberration. what do you think about this?

For clarification on Warlords and Primary Detachments:

Quote :

...If you organise your army using the Battle-forged
method, whichever Detachment contains your Warlord is your Primary Detachment. If
you used the Unbound method, then once you choose your Warlord, every model in your
army that has the same Faction as your Warlord is considered to be part of the Primary
Detachment...

Doesn't that mean I would have to have 2 elite choices separate from my detachment for them to be the primary detachment.

As all the formations and detachements are Dark Eldar they are not considered allied detachments as stated in the Haemunculi Supplement:

Quote :

You can add the Detachment and Formations from this section to an existing army, or use them to field an army from the Covens themselves.

Allied detachment requriements:

Quote :

RESTRICTIONS
This Detachment cannot be your Primary Detachment.
Your Warlord can never be chosen from this Detachment.
All units chosen must have the same Faction (or no Faction).
All units chosen must have a different Faction to any of the units in your Primary Detachment (or no Faction).

Elites are not requirements for either the CAD or RSR detachments so you don't need them.

For the coven to be your main detachment you need to have 1 hq and 2 elites, I an confused I only have the codex de and coven supplement.

I'm flipping through the Haemonculus Coven Supplement and I'm not seeing where it states that the main detachment must have 1 HQ and 2 Elites, could you point me to the section that states this?

Actually the only formation I'm seeing that has a requirement of 1 HQ and 2 Elites is the Grotesquerie which is the entire formation. The Covenite Coterie Detachment requires 2 HQ and 2 Elites.

Maybe I have misinterpreted the rules, because I did want the coven element as the main detachment.

From what I understand from the rules that is perfectly legal to do, pick the Haemonculus' Coven detachment that you want to be your primary and declare him your Warlord, that detachment is now your primary detachment. All of your detachments are battleforged as they meet the requirements of their respective detachments.
