Final Phase of FRS MK51 IN issues..
Dear John sir..
In first place I would like to convey my apology for not getting back on the harried unintended roll issues as I had got transferred out shortly there after...
A brief on the previous problem.. We had carried out all kinds of combinations as you suggested and with no result we were about to name "the rogue" as the rogue again... However the problem was solved by replacement of fin.. Which to our surprise the least suspected part... The aircraft is still up in the air and she is as beautiful... Just did a 90deg turn during hover and landed her...
Thank you sir...
