Rob, I could not agree more. My son and i are building 8 of the EXI 450 clones and there beautiful. Plastic yes, were sport flyers i cannot justify spending $650.00 to $1000.00 for a heli. 8 of these structures cost me $240.00 under a hundred to finish with our spectrumDX6Is. A few minor problems with vibration some screws vibrating out but for this price we can solve this problem. We've been flying one for a month now still have it!! The others are pending parts i can wait. It is a joy to build these helis. We followed a build from MikeysRC.com he used all low end parts has been flying his for two years. The same 8 helis would cost us about $5000.00 own. Ron some help on vibration if you have any ideas please let me know. Thanks, mike scott, [email protected]
