Greg,
If you are using the Hacker A150 or the Hacker A200 all of the ESC's currently sold by Castle Creations won't work as they will not be able to meet the demands of the motors in terms of the amps & number of Lipo's needed to power the motors. They used to sell a 250amp SHV (Super High Voltage) ESC capable of handling 90 volts but they no longer make it. They had a 400 amp ESC in development but that never came to fruition.
Innov8tive Designs, maker of Scorpion brand motors & ESC's, has 3 high voltage ESC in development capable of 16s. You might be able to get one though since you would be promoting their product as part of this build. The new 300 amp, 16 cell ESC from Scorpion Motors is capable of up to 20,000 watts of electric power (go to page 281 of the forum):

I have spoken to him on 2 different occasions as well as through the Innov8tive Designs forum. Towards the beginning of the year he told me it would be available mid 2010.
For ESC for both motors try this:

The Jetti 220amp ESC will work with the Hacker A150 but not the A200.

Finally the latest ESC on the market is the 16s, 63 volt, 250amp X-Series made by MGM-Compro.

Here is a pic of the ESC:

Check out my install of the A200 in the Hangar 9 46% Ultimate.

You'll need the 14s set up as anything less will not give you the performance required for this plane.

The propeller drill guide for both the Hacker A150 & A200 is the same as the one sold by PSP Mfg for the DA150
