In my Roo kit, I did not recieve the (white) airbrake hinges that are in the assembly pictures. I recieved (instead I believe) 2 Robart Hinge Point type hinges. These Robart ones do not look as strong/large as the white ones pictured. I don't feel like waiting go get the correct ones from CompARF. Should I use 4 of the Robart type ? Thanks again. Bob

The two Robart will work just fine and stand up well.
