RE: Extreme Flight 88
The Robart hinge points are a little better IMO. The hinges have a little less play in them. Tell you the truth both work but I'd do it with Robarts if I did it again. I have a big bag of Robarts that I have for backups in case the EF ones are cut too short (the EF ones are cut too short for my tastes on the stabs). My two year old Extra has some play in the stab hinges. Rudder too.
