Skip,
Gbee is right, search for the u-can-do-3d thread. Its an old and long thread with about 53 pages. I think all questions have been asked and answered profusely there.
In addition, if you want to see a video of how the UCD 60 performs with a Saito 100 go to
http://www.3dbatix.com./ , click Videos then go to page 2 and look for "H9 Funtana vs UCD3D Torq off challenge". Its not a fair challenge since the Funtana is a smaller lighter plane but you can see how the UCD performs.
The following is a quote from the flier of the UCD:
ORIGINAL: mecam
Both planes have Saito 100s and APC 16x4W on UCD and APC 15x4W on Funtana. The funtana is 1lb lighter only but takes off like a rocket and leaves my UCD behind.
If you want to read the thread where his post appears just type mecam in the search window.
