Got mine built today

and have a few queries.
The servo holder is in plastic and not alu like the 410
Servo/steering rack as well thats only got 2 holes, the third not necessary?
Another thing is that one of the spur holders are in plastic and not 2 alu ones like the 410 ( they are not the same height either so a spacer will have to be made)
Are people swapping over these things from the 410? Or are the seen to be fine in plastic?
Im going to do my splatter paint tomorrow and I have some sexy CF protection on the underside of the chassis.
Going to sell my 410 if anyones interested
