Ordered these to use to space out my servo on my yz-2, Well they didn't do as I wanted as the round end's slide into the servo tab's when tightened. However they did work on another rc I have so all is good. This is also the first time ordering from Beachrc.Com and all I can say is wow.. Fast shipping, Great communication and excellent Prices... What more can I say,. Looks like I found my new online Hobby store.. Way to go Beachrc.Com !!
