I have had a blade cp for some time now and I just got a 30 size nitro machine. For me the nitro machine seems much more intimidating to fly, but it also feels like a sloth compared to the blade.

In the wind the blade is very hard to keep in one spot, but the larger machine doesn't even seem to notice it.

Basicly, the two machines feel completely different and if you can fly the blade AT ALL, a gas machine will be easy.
