In a word - wrong, the 33 is the heavyweight of the trio (although it is not that much heavier!) I'd still go the 34, much more refined. HPI did quote that the order of quickness was 32, 34, 33 - but once you start to mod them it doesn't matter, they all use the same drivetain, but with improvements in the computer systems in subsequent models.
Although I love my 32, I think the 34 is a great car, if I had the folding stuff I'd get a 34
I've never been too keen on the 33.
