Intake Plenum Mod Update …DanH
Promised more after I flew it a while. I'm pleased. Here's a shot from late June, with numbers that have proven to be typical. Solo, toward the end of a long leg, so light on payload and fuel.

Riveting trailing edge with squeezer …Dr_Dave_MT reply
Same Side. Pneumatic Squeezer. Spaced 5 holes apart. Groups #1 A-B-C-D then 1/3 squeeze group 1, 1/3 squeeze group A; etc. Alternating pressures across the TE. Nothing burger with cheese for me...

Intake Plenum Mod

Riveting trailing edge with squeezer
I’m about to assemble the rudder, and I’ve been reading and rereading about getting a straight trailing edge. Even Section 5 states: “Building a truly straight TE is one of the more difficult things to do in aircraft construction” If you are using a pneumatic squeezer with the trailing edge...
