servo saver
 

can i use the ue gen 4 servo saver on the g2r? if so is it a drop in fit?

I'm not 100% sure myself, but I think the revo has a completely different steering bellcrank to the maxx. I think you'd be better off with this: http://www.rc-monster.com/radio.php , (at the bottom of the page).

It uses the revo saver.

how tough is the revo saver?

The revo saver should never break, and if it does, the integy looks prettty good.

thanks!
