Hi Mark,
I have mounted the speed sensor several ways; in the nose, in the fin and on the side of the fuse in a mount. My least favorite is the nose. Everytime that you go off-road or when your NG fails to lock in the down position you will knock the speed sensor off if it is mounted on the nose. Of course, this shouldn't be an issue if you never have those problems. I'm not that lucky.
I really like the speed sensor mount that I purchased from Tad at Golden West Models for my BobCat. I have attached a picture of the mount on my BobCat. I will also include a photo of the speedsensor mounted in the vertical fin of my F-16. Both the vertical fin and the fuse mount are excellent solutions.
