Have you ever had an issue getting a set of Robart 615's to fit in any one of your Corairs. I seem to be hitting my head on a wall tonight try to get them to sit properly. When I get them set on the the rails the music wire hits on the bottom of the cut on on the main spar. I knotched it down a bit more to clear the piano wire. Then I realized that when closed it's hitting my tire at an angle and won't fit. The tire is a 1" thick Robart and I don't have any room to fit it down in the wing deeper. I seem to need about another 1/8 inch of clearance to fit level. I'm a bit concerned about carving out the wheel anymore and weaking the structure there.
If you happen to have a pic of 615's mounted up I would appreciate it. I can't seem to find a good one in the Forums at the moment."
Since this is on the subject of 615s, I'd rather answer here so everybody can read it:
Yes, I do a simple mod which has the effect of lowering the retracted strut/ wheel slightly, while increasing the forward angle when the gear is down: I install wedges between the retract units and the mounting rails; These wedges are made from Ernst thrust plates: the 3 degree offset/ smaller size ones. I can get a couple of sets from each plate. I cut them to same length as the retracts, then drill them so the mounting bolts will pass thru them. Then I silcone them to the retract units. That is my solution, others may have differnt ideas? I'll try to post a pictice (much) later today.
