How to estimate times when working on a new technology? [closed]

Question

I have been working on Flex for last couple of months and as this was the first time I had to actually do Flex I ended up underestimating the project tasks which resulted in a delay. So how does one estimate the project timings when working on a new technology?

Answer 1

You can't.

You have to consider it as research, and research can't be estimated.
