HS 65 HB's for me. I saw one fly on 4s with them...worked alot better.
LOL....I don't know why you guys want 4S and speeds up to 110mph, but I know it's a personal choice. Even as stock for me, this thing is REAL hard to keep track of if flying full speed. I could see where even as stock running full power, smaller servos would be under tremendous stress (such as 7.5's or 8G servos), and would give out, especially under high G manuvers. My next one will have minimal 9G servos....and I don't push mine that hard.
