[NSRCA-discussion] Robart air can leak

[Ken Thompson]

Del,

Since this is on my scale T-34 Mentor, weight is not an issue.  My only 
problem, in trying something not guaranteed to work, is having to remove a 
section of the bottom of the plane to take the can back out if the repair 
fails after a dozen flights.  I found that the leak was caused by hitting 
the can with a hobby knife, that's how thin the thing is.  I think I'll buy 
a new can, one time repair, all good.

Ken
