I placed my order Monday and recieved my package Thursday.Keep in mind that they are in Southern Cal. and Im in Northern Cal.So you decide if thats fast or not.I recieved my order in a box that was alot larger then what was needed for a CNC head and tail upgrade that included (2) sets of 325 carbon fiber main blades.I added(1)set of carbon fiber tail blades also.My complaint with the box size is this, it allowed things to move around inside too freely and is probably the reason the shaft on the new CNC tail was bent adding $7.00 more to this order and a trip to my LHS!Complaint #2)The carbon tail blades I recieved looked nothing like the picture online!I know that this is kinda shallow, but the appearance of my bird is important too. The Main blades that came in the package deal were white with black carbon fiber lettering saying "3D" and the tail blades I thought I ordered were white with "3D" that matched the mains, nope..They were dark with a carbon fiber pattern, nothing like the picture displayed online!#3.No instructions at all, good thing I did my homework and researched things before ordering or it would have taken alot longer to install on my Heli! Im still doing my feild set up on it.I had just bought a new Logictech 2100 gyro a week prior,so set up is taking some time! All in all, I did this upgrade because there was just too much slop in the stock Blade 400 head for me and the CNC upgrade did fix that,but Im still not sure about the CNC tail yet.Its tricky to get on at first and the frame seems like any little mis-hap could possibly mess with its "precision".Both pieces make my Heli a little heavier.IMHO its better for my Blade 400 because its flown outside only and as with any 450 class heli,just a slight breeze changes the way it handles.In closing I dont have enough time with this upgrade yet to give an honest opinion on its effects, good or bad,on my perticular heli.I will update after I spend some time with it.
