Looking for a Hi Fill primer... one that will fill in most of the rivet edges and sand easy.... does not need to be an epoxy, as I will use a zink epoxy under this fill primer... Any one doing this? Thinking I can cover the rivet edges with two coats, lots of sanding in between... each coat would be...

As a General rule... Primers are not intended to be Top Coats... If the primer is an Epoxy it will quickly degrade (3-6 months) if exposed directly (horz surface) to sunlight... the UV is what breaks down the chemical bonds in the Epoxy. The first sign is that it will "Yellow" ... this is true for E...

The FAR stuff is Fantastic. ..... Thanks Spike I'm going to do the painting, white on top Blue on the bottom At the line where they meet. I'm trying to get a local Truck Graphics shop to make me a swoopy colored Vinyl stripe for the Fuze side another for the wings and the vert and horz tail and inst...

Easy Question ..... Easy answer???? Do I need to use a FAA Certified paint shop for painting My RV7? Also if I want to have stripes put on by another Auto Detailer, do they need to be a FAA shop? If ... NO .... What FAA / EAA / AOPA / FAR / VAN's document can I show these shops so they can see that ...

One other thing to watch out for ..... if you use as Crow foot on the end of your torque wrench ... you must re-calculate the torque deliverd to the fastener. 100 in-lbs on the dial will deliver 100 + the fastener. The torque wrench is calibrated to deliver the value ... only when the center of the ...

Looking good... we are just getting to the point of rigging the elevator to the control column.

Did you have any problems with setting the elevator stops? Especially the full fwd stick travel??

WAY TOO MUCH EFFORT TO POST A PICTURE for me... After an hour of going thru the twists and turns of old treads I did find my way to the close to the end.... I don't have an Album... Once I get that I need to figure out how to get pic to the Album... Thanks... but no thanks... If ya'all are intereste...

Here is some pics of the right flap ski jump...

Pete Just finished "FIXING" the Ski Jump... Van's send me the Tool... The Top skin over the flap is now in contour with the wing .. Flap seals tightly to the top skin ... The foot print of the Van's tool is only 3 inches, so you get to take many bites. Found that if you bite every 2 rivets, it makes...

HELP.... My QB kit has the rear bulkhead installed. Guess what? It's not verticle! So when I try to set the Vert Stab against the bulkhead, up against the elevator stop, it bows in the middle. So when I run the Plumb bob string down the three rudder hinges holes it will not true up. The middle hinge...

CJ I remember that RV article... Flutter is one of the problems, but some one tried to explain to me the "over stressing the airframe problem".. Here goes i'll try to explain what I learned. The fast air moving over the wing is flutter ... The second is the mass of the plane moving in a straight lin...

Peter Good read... Any Hp above 210 is wasted.. The 7A does have a Vne of 200 kts. With 210 hp @ 8000 ft you will be over Vne. Remember Vne is TRUE AIRSPEED... not indicated. Our planed engine is Aerosport (same as what's in Van's RV7A) IO 360 paralle valve... with dual light speeds.. 8.5 to 1 comp....

Pete We have a 7A QB .. shipped to us in Sep 05. It has the Ski Jump Top Skin TE... Last wek we were at Sun 'n Fun and the flap to Top skin distance is "line to Line"... ours has a 0.075" gap.. Now I know why... Flaps fit ok, right at the min edge distance. We will have to remove the Aileron and Fla...

So just add that drag from the bolt / screw as it nears the botom of the travel.... We have a "Click " type wrench .... so I could find the amount then add it to the total...

That works

We are getting ready to do some final Torquing of nuts on some areas in the wing.... if they are Lock nuts or bolts going into lock nut plates, how does one set the torque on the wrench???

I had the same problem on my seat backs ..jim. The alum skin would not stay flush to the angle... drilled out 4 or 5 before I tried it the right way. I have a talked to many Old rivetbangers about this subject and the best story that I got...was from an engineer that worked at Douglas when they were...

Quick build all the way.... Since this is my first time building I had 2 main reasons why QB 1. I want to fly ... not build 2. I want the Factory building experts to build the structural sections With a partner, we finished all but the glass work on the emp parts in 5 days @ Alex Tech, Griffin GA......
