front can be modified to change the angle as well.

If you haven't already drilled your TS1's just mount them as low as you can
to still get the bolts in the fin post. IF you have already done it...many
TS-2's have been "relieved" in a semi circle cutout to clear the FUS-30. If
still concerned the TS-2 is going to get too thin...sure space it down a
bit
as you have said with a spacer between the TS-1 and -2. Clamp section
should
be perpendicular to the post...ie not tipped forward or backwards. Just
round off the edges slightly so they don't cut into the tailspring as it
works up and down. Then adjust the spacer between the FUS-30 and tailspring
to match where the clamp places the forward end of your spring.

Cheers,
Wayne

30,

and the way I made the initial bends made it so I can't get it sucked in

at

the bottom rear. There is about a 3/16 gap between the FUS 30 and the

else, and I figure I will stick it on with proseal and it should be

bomber.

My problem though is that it will interfere too much with the TS-2 when
