Mmmm.. stay away from Kevlar as much as posible. How about this, I had a Deans base loaded antenna in my 45. cap 21 well, one day I just forgot to install the antenna on the base...............after the flight ( and we did all kinds of things and flew far away too ) I saw that the antenna was gone, to my surprice it was still in the fuse were I keep it for transportation so I wouldn't forget to screw it on the top of the model, how about that, the Cap flew and flew for 10 minutes without the antennaand no gliches at all.

Extra300 nice work on the install.
