Any of the 2nd type planes will fly more quickly than any trainer and have much quicker reaction times. The flight differences are quite schocking and a pleasent surprize as long as you have the stick time to be able to appreciate it. If you don't, things can get out of control very quickly. I have a Kaos 60 and it would make a good 2nd plane because when things get out of hand, it can be slowed to a crawl and still fly well. I also have a Tiger 2 and I like it better than the Kaos. I also think it looks better. The 4*s float way too much for my likeing. The Tiger2 has a solid predictable decent rate which makes landings a breeze even in windy conditions. Tha Kaos landing characteristics are sort of between the 4* and the Tiger2.[8D]
