Well I had a 330L until today. Yes I crashed it. The hardware was POS and the instructions are just inadequate. I worked with this model for about a month trying to get the weight and CG right. I could not get any tech support from CMP or the company I got the 330L from. I guess you get what you pay for.

On take off the right wing clipped the runway and at this point the wing tube bent. Then the plane snapped and ripped the left wing off. It did not even hit that hard but the model was trashed.

I can not recommend to any one to buy a CMP model.
