the EVO uses a machined 2.5mm alloy center plate that reduces complexity and weight while increasing the airframes stiffness.

the newer EVO arms are backwards compatible with the full carbon raptors

arm and brace kit to turn your raptor 210 SX quad into the true X airframe with a 205mm wheel base and clearance for 5.2" props 

so this beast is my personal take on a mid mount acro frame. she is one of the lowest designs with a 10mm avioincs bay with your stack split accross the bottom deck. while im a 4n1 kinda guy you could use an AIO type fc and escs under the arms. it has some interesting ideas going on with the spit stack and the top mounted pressnuts that mean if you release all the arm bolts you can remove the battey plate and access the electronics with the arms and spacers all staying in place 

airframe is around 110g built with hardware
