The TeleScience board supports connection of up to 12 NTC thermistors along
with other capabilities.
-Installing the electronics in the fin can bay was .. interesting. More later.
+Installing the electronics in the fin can bay is a *huge* challenge due to the
+restricted space between the MMT and airframe.
## Build

The fins are 3/16 inch birch ply, tapered on the leading and trailing edges,

We're moving from the Giant Leap Rocketry 98mm Magnaframe-based Dynawind to
G-10 glass tubing this time around. Dynawind is lighter and strong enough,
All rings and bulkheads were cut using a CNC milling machine from 3/8 inch
birch plywood. The fin forward and leading edge rings are made from 3/4 inch
-thick assemblies made by laminating two such rings with wood glue, to provide
-sufficient depth for milled fin slots.

Will add a pointer to build photos here once they are available.
