Zeus and Apis drones

Hello, I don't know if this is the right place to post this. Anyway, how many parts do you guys think is the right to buy Apis and Zeus drones?

 

I can't remember how many part it takes but I normally wait until they cost between 200k - 300k to instantly buy with uridium, after that I feel like the uridium spent on keys to find the parts isn't worth it. Just make sure for the Apis you take advantage of the double Apis chance day, you get double the chance of finding blue prints and double the chance of finding a full drone.

Alternately for the Apis you can use all your keys for LF4 and just build the full Apis whenever you get the 45 blue prints, since you will get them before you get all LF4.

 

Sometimes I think it's a waste of uridium to try to take zeus parts, because it usually takes more than 30 keys to find a blueprint, and 30 keys = 45k uri, that is the ammount the price go lower on the start of building, I'm palling for zetas and saving uri now, but when I take my havocs, I think I'll buy zeus. The apis I'll probably wait for 45 parts, I usually take like 3 parts from keys I use on LF4 or Zeus event.

 

from what i think, get them to 20 parts then buy it, after 20 parts, the price goes down 10k each part, i believe it something like tht

 

At 24 parts on apis day with discount cost me between 130k-140k for apis drone. The big Z i got lucky
