I'm way new at this heli thing I got a blade 450 3d I have 40 hover flights and getting comfy and ready to move out of my comfy zone and practice moving around allot more witch turns out to more repairing....I've stripped a servo I think the heli just moved by it self and did a flip upside down right in the ground a servo was buzzing like crazy...and was thinking about metal gears servo... but was thinking at this early of a stage I'm at in my learning curve and I have a bunch more crash's coming up is it better to strip a plastic gears and just keep replacing the gear or would metal gear last longer and do more damage to the heli on every crash? so go metal gear's? or just stay with the plastic?
