I spoke with Bob about the holes in the wing skin close to the edge of the material. He agreed with my guess that it would be OK because of the .032... -
The holes do look too close to the edge of the material especially on that side to the left in the picture. The "frame" that gets riveted inside...Leave a comment:

Usually there is a section of rubber line that connects the fuselage to the L/G legs. On that "rib" at the top of the L/G leg - usually a bulkhead...Leave a comment:

We will be doing these for the Patrol. But they are not identical. The Patrol cap strips are 1" wide and the Model B & Model 5 have cap strips... -
We do not have a weight savings number. Perhaps we should weigh an original spar and a new one to see. If we can still do that as going forward we hope...Leave a comment:

One piece spar cap strips
During the internet "virtual get together" I mentioned that we are changing how the main spars are built for the Model 5 and Model B. Instead... -
There is a Bearhawk in Alaska flying with Edo 2870's which he thinks are the perfect floats for the plane. If you contact me privately I can give you...Leave a comment:

And congratulations for finishing and flying your plans built Patrol. Quite an accomplishment. Mark -
It was the upper right wire on my LSA. Another factor could be the vibration of the whole tail at certain airspeeds or engine RPM. If you have a camera... -
We found on the LSA that this type of end fitting for the tailwires resulted in everything being too rigid which resulted in harmonics/vibration/cracking....Leave a comment:

There were some "Bearhawk" fuselages made there in SA with material not spec'd on the plans. The fuselages were also "redesigned"....Leave a comment:

Josh, I can help you figure out what it would cost to build a plane from our QB kit. But not here in the forum. If you want to email me - N95MF@hot...Leave a comment:

I do not quite understand the fix you are suggesting Paul. Most just epoxy in or rivet a rub block. Mark -
The windshield lower fairing looks good John. Mark -
For the engine compartment there are some "high temp" zip ties. Not a bad way to go where it is hot. Mark -
I like to cover a small table or surface with wax paper. And wet out the cut strips of fiberglass cloth laying flat on the table. The wet out strips...Leave a comment:

Your summary is 99% correct Brooks. The only correction is that the Companion is not really a lightweight Model A fuselage. It has all the Model B features...
