What Servos Should I Get

[3dbandit]

Hey guys.

I am looking to get a new set of servos for the new 104 EF extra i will start building in a few days.

I lost my old 104 because my JR 8911's began failing and caused violent flutter that blew off the tail last weekend.
They twitched on the ground like they had Parkinson.

Any one have any idea what servos will hold up to the abuse I will give them? I need a minimum of 480 oz and .12 sec transit time, I prefer titanium gears.


Thanks,
Jacob
