Sorry guys I haven't put any information up
I got ripped off by this online company

http://www.e-clec-tech.com

Never got the servos and they were way over priced

but it was a lesson learned.

I had to re order the servos but this time it is from amazon so this time I should receive my item.

Also I have the flu and I have been in bed for a week
it sucks but I will get better.

As for the cap

It is connected to pin 1 and 3 of the IR IC which is in the schematic
