[TowerTalk] adding 40 mtrs to C3

[Bob K6UJ]

I have a Force 12 C3 and I'm considering buying their 40 meter dipole to mount on the boom of the C3.

A couple of questions for someone that has done this to their C3:

How does it perform on 40 meters?
I have a copy of the C4 manual (which is a C3 with the 40 meter dipole) and it doesn't show 
a dimension locating the 40M dipole on the boom, is there already a pre-drilled hole for adding the dipole ?
Lastly, how difficult was it to install on the boom of the C3 ?  I think my C3 has their easy on mount,
can I rotate the C3 on the mast and install the dipole without taking the C3 down off the tower ? (I hope)
