Not really. Kaitenage is actually quite different than a whizzer. First off, kaitenage is an underhook on a person's arm, while a whizzer is an overhook. Kaitenage is focused on control near the elbow joint while the higher a whizzer is, the better.
I'll take your word for it Keith, its 4 years since I did jujitsu now, for me kaiten nage is just a generic term I've seen used for these rotational throws which vary widely across the various teaching styles of aikido.
