Gr2 and GR3 differences ?
 

I mailed GM but got no reply . What parts were actually changed from the GR2 to the GR3 ? I can tell from pics the rear upper plate is different and they added an esc mount but what else ? thanks, Jerry
p.s. the cf GR3 I just recieved I believe is actually a GR2 but need to know for sure.

The X-braces were 'hollowed out' on the G2 if you look at them from underneath, where-as the G3 braces are solid with no milling-out done to save weight = stronger but heavier. The upper plates & lower battery plate are also thicker- 3mm vs 2mm on the older chassis.

Thanks again !!!
