I bought a futaba MJ 2 channel radio control system combo from Rcmart and contains two of these servos. This radio system i bought it for my second car that i use only for drift and because this radio was cheap. When i first assemble this servo in my drift car didnt have much expectations and when it was all done and functinable i was amazed. This steering servo works much much faster than my other servo i have in my first car Acoms 2,4 G II, and i couldnt believe my eyes on this. Futaba stock servo is quicker and more reliable than an servo contained in an much more expensive radio control system combo. Luckily the futaba radio control system combo comes with two servos and as all my car are electric and need only one for running i did what every wise driver would do. I replace the acoms servo with the futaba one and now both my cars turn equal fast. Thank you futaba and rcmart once again for great products and fast shipping. Definately five stars for this servo at this price.
