These are the new (22.5.2013) released v3 Reconn plates (Fibreglass) for customers with existing 2012 Reconn v2 or Armours who want to upgrade and swap to bigger plates - they are fibrglass FR4G10. This will give you a bigger frame which is only slightly heavier than the old v2 set ( 5 plates = 140g vs much smaller 4 plates = 96g of the old version) even though the tail plates are much stronger in the new version. Also you will have a lot more space for FPV gear and a bigger more stable stable Quad.
Weight set of 5 frame parts = 141g
Fits any existing v2 boom holders for Scarab - Does not fit the orginal 2011 v1 boom holders
5 x Frame plates as shown including tail and upper protection plates
Requires Scarab frame hardware sold on this site separately - You will need to order additional 21mm shafts and M2 screws ; standoffs and other parts if you dont have these already - these plates do NOT come with anything else that is not shown - it is a basic frames only set - do NOT order this alone and expect there to be other parts by magic - what you see is what you get here - The idea is that you re-use your existing parts and buy anything alse you need as well - separately
