DON"E USE CHEAP SERVO'

what ever u do don't but t-pro 3.50 servo yeah they work but the littlist bump or blade touch they break or die plus the plasitc is so weak just mounting them you can break/crack the mounting area of the servo save yourself the time and frustration and spend at least 10 bucks a servo 30 if u want real good one but not really needed but anything below 7 or 8 bucks aren't worth even looking at...... ive learned this past weeked end its not worth buying cheap stuff when it comes to heli's these 3.50 ones prob work great on airplanes but heli's are so hign presision they need almost the best you can get with out going to crazy so any one building there first heli just a word of advise i must of built /unbuilt and rebuilt 5 times this weeked just switching out servos and trying to get them working good


BWT. a good ideas is to avoid any servos that u can see in gears inside very cheap clear ones or like the dark ones that u can still kinda see them, inside

sorry to hear you aren't having any luck with them, I used them for months without any probs in my old EXI 450.
