ahh this has beena great day for me im just sitting here smiling like crazy as to how much money i am now going to save. and now i found all the 3 sizes of hxt servos i need for any application i will ever need. got the hxt900's for ahything amaller then .25 so im hoping i can use the 900;s in my little house of balsa .10 mustang 1 1/2 . il use the hxt5010's in my sundowner and my winter build thunderbolt and il use the mg14's in anything .25 size..god im literally laughing..lol..heres hoping they dont crap out and take my plane into the dirt,lol. oh um i would assume those hxt5010's would also work great in a sundowner formula 1, 80inch, 25% though i might have to use 2 per wing half i believe.
