Hey Dave those are the stock s75s, a freak of the flash made them transparent. Cool, huh? I wish it really looked like that. But with the new MH head I can really feel the slop in these servos, out they go, HS55s on the way. Blue transparent cases!

I just got bigger balls! I mean that I replaced most all the MX400 aluminum link balls with the Align stainless steel balls, they are just sufficiently bigger enough to remove all play in the linkages without binding. It has made an unbelievable difference in the handling of the MX400Pro. I just hovered off a whole 2250 mAh pack--right here in my little living room, climbing and swooping like I do with the Blade CPPro. It is really stable yet instantly responsive with no slop. Mechanical ccpm! I can't wait to get it outside.
