VT 21 Needle housing problem

Postby jwitham » Wed Sep 02, 2009 8:04 pm

I have an older HP VT 21 that i have run a lot and lately the needle housing and spring have been popping out on occasion. I have re-glued with loctite red 272 but it only seems to last a few flights. is there a better bonding sealant to use?
