Estes Photon Probe #3026 Build, Part 9, Dorsal Fin Gluing
The strange thing is - The Dorsal Fins are centered on the strips. The strips aren't much wider than the 3/32" thick fins. these will be a chore to fillet and get a smooth joint during finishing.
The dorsal strip fins are set directly above the main low fins, 2 3/4" from the end of the main tube.
Instead of using a ruler to mark the dorsal positions, I made a marking guide for consistency.
The 5/8" and 2 3/8" marks are from the newer kit instructions. EDIT: As noted out in a comment, I got this wrong! The 5/8" measurement was from the top of the taper in the new instructions.
A paper strip was wrapped around the body for a consistent trailing edge position.
You'd think the larger dorsal fins would go to the rear but the smaller rectangular fins are to the back of the strips.
