I am really curious to know how that 130x flies with all them upgrades, for me i have a 120 sr and a msr. I c alot of people hop them up and just kill the over all performance of the heli. its all trialand error with upgrades. at the same time some things do and need to be upgraded. for instance one my blade helis the only things that are getting upgraded are the swash plates. for on on the msr the balls tend to break when popping off the links, and the sr and upgraded swash helps to handle the wind a bit better. but its a personal preference. plus the more stock parts you have the less cost of crash damage you will have. this is true for the smaller blade helis anyway. I just dont want you to spend all sorts of money and be disappointed. however i see going through your post the money was already spent. However this may be something to consider in the future.
