Here's some tips you may find useful:
When recording a hand drum with an open bottom (like a conga or djembe) try a room with either a hard floor, or if you are in a room with carpeting, put a piece of plywood down under the drum. The idea is to allow the sound coming out of the bottom to reflect back up into the room and the mics.
Try these possible mic positions and see which works best for you:
1) SM57 about 6 inches from skin, with the V93 about 4 feet away, aimed at top head.
2) SM57 about 6 inches from skin, with V93 about a foot from bottom of drum, aimed at bottom hole.
3) V93 about 3 feet away aimed at top head, with SM57 about 6" from bottom hole.
Record a little of each position and see what works best in your room with this particular music. As far as exact placement of V93 when used as a "distant" mic, be sure to try old standard trick of either walking around room listening with one ear until you find the spot where the drum sounds best (and put mic there) or else put on headphones and carry the mic around until you hear the best sound.
(By the way, you may also find that just one mic does the job. Certainly nothing wrong with that, either!) Let us know what worked for you.
