Craig Thomas Posted November 24, 2015 Share Posted November 24, 2015 Hi all I have a seagull Edge 540 and need to replace the elevator hinges. I've already had to replace the aileron hinges as the supplied CA hinges snapped. Fortunately I noticed on a pre flight check. Now I've noticed that the elevator hinges are snapping. Why would this happen? Plane is only 1 year old. So my question is what size Robart hinges should I use. I'm unsure what size I used on the ailerons but fell they may to to big for the elevator? Any suggestions? Quote Link to comment Share on other sites More sharing options...

Matt Jones Posted November 24, 2015 Share Posted November 24, 2015 Robart ones, larger size. No question for me. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted November 24, 2015 Share Posted November 24, 2015 If you remove the old ones with a scalpel, you'll be able to fit some large Kavan ones John Quote Link to comment Share on other sites More sharing options...
ChrisB Posted November 24, 2015 Share Posted November 24, 2015 I only use kavan and robart hinges these days. I've had several sets of these CA hinges fail on various types of aircraft in the past and its because the CA goes brittle through vibration.The first thing I do with IC artf models is throw the hinges away they are a waste of time.

Craig Thomas Posted November 25, 2015 Author Share Posted November 25, 2015 When you say Kavan hinges, do you mean there pin hinges? Never used those type before. Only uses ca and Robart. Think I will opt for robart but not sure whet size. Think I'll just order a pack of easy and see what size will suit when they arrive. Thanks for help guys.
