I would say the Blade 450 is the lowest quality 'current' helicopter I would recommend to a beginner, and I think Trex is right in the middle.
Listen to the sound of these machines - listen to the Rave, how smooth it is compared to the HK-450 I posted earlier. The sound of a helicopter indicates how well the parts are working together - louder sound = lower quality. Used to be - that's how we tuned car engines - by sound. Now we have computers that tell you how well the car is running, but the skill of determining a machine's general health by sound is still important - develop that skill, it will help you. You should be able to hear the helicopter making a few distinct different sounds, and those sounds will tell you how healthy each system is. You can hear the blades, the main drive, the tail drive, and the tail blades - just like picking out one instrument in an orchestra, you can pick out one of those sounds and concentrate on it, and learn if your machine is working right.
I still can't believe people let me fly their helicopters, but here it is... this machine is very high quality. When we switched it over to flybarless, it flew almost the same. When the computer can't correct anything, it was pretty darn good to begin with.
I fly (try to) a HK 450 and a 250 as well as the V120s, and I'm no mechanical engineer but even I can tell by the general build quality that they are pretty average really, but good for the price and useful as a training tool. I look forward to the time when I feel confident enough that I can spool up a quality heli knowing that their's a good chance it will return like it left.
Thanks for all your advice
