Both my Artes Bee and Falcon have spool up times of about three seconds from idle to full throttle. That was one reason I bought them. The almost instantaneous throttle response could save your plane if you need to go around or to get out of a difficult situation.

One of the most remarkable RC events I saw was with my buddy's Super Eagle/Gripen. He came in hot and did a bad nose up bounce. The plane was falling tail down and nose at about 11 o'clock when he gave it full throttle. I thought it was a goner for sure. It got to about 6 feet off the ground then took off like a rocket. Yes, I know the plane is overpowered, but if that was a Jetcat in it the plane would have crashed for sure.
