Default 1/2a Rivets Build!

So I got my Rivets kit from Vicman last week. Its one of the last, he told me, so Its gotta be built good. I wouldn't say its exactly a beginners type build, but it shouldn't be too tough to put together. The plan is; Spruce Spars, Elastic wing attachment, Tubeless Torque Rods, and a Dowel leading edge. Power will either be the Tuned Cox from my mouse racer or a novel .061. Im thinking the norvel might be a little overkill, but thats always fun in my books.

Tonight I started with the fuse. So far so good. I will take pics of the process soon but for now my camera is at work.

One question I still have floating around is the Elevator push rod. How should I do this? I was thinking a gradually bent tube through the fuse coming up the side of the vertical stab, good or bad Idea? Or is linkage the best way to go.

Is anyone else building one now too?

I had a rivets a long time ago. I will say only this. Make sure that your fin is strong enough to hold the T tail.

I have the original that Bob built , the control rod is straight out of the fuse on the right side at about a 30 degree angle, no bends, probably one of the last things fittted to the plane..Rog

I did mine with steel cable and glued the carrier tube into the vertical to hide everything. The end of the cable was tinned with solder and a z-bend into the control horn. I also tinned the end of the cable that goes to the servo for stiffness.
When I get back home I'll take a picture of it so you can see what I did.
You might be able to see something from this photo too.

This plane looks so cool in the air. It has a character all its own, like a little Jetsons car, or something.

forsakenrider, Do you have the correct plans? The racer version had a bolt on wing with a balsa leading edge. I used the older single channel plans as an out line only and beefed her up for 1/2A racing.

Rog does have the last one I built. The first 1/2A Rivets racer flew many years ago with a Tee Dee .051,Glow Bee plug and 45% Nitro so I’m sure it will handle the Norvel. As I recall it even beat John Gibson’s delta in one race.

I used a 1/6 piano wire pushrod going up to the elevator. My plans show using a Goldberg aileron bellcrank at the tail connecting up to the elevator. This does work but I was trying to get it race ready and did not have the time to install the linkage.

My plans also show recessing the vertical tail into the 3/8 balsa ridge on the top of the fuselage about 3/16. The tail is glued on at zero incidence. This is done by positioning the fuselage on flat surface and use a level to insure the horizontal tail is also level. Very strong as I cart wheeled her several time with no issues.

Set up right she flies like on rails and is a ball to fly. Balance her about 4-1/2 inches from the TRAILING EDGE for starters and you will do fine.

Thanks Vic. I've had a few guys ask why the laser cutting did not fit Owen Kampen's plan.

Vicman, you are not supposed to display pictures of that Rivets. Rog is still suffering from Post Tramatic Stress Syndrome from that near miss.

Yes bob I have your plans, but vic told me a few secrets. Like the elastic wing jobby he did. The Dowel LE might be a secret weapon for enemy destruction....... HA!

Im not diggin the bellcrank linkage Idea. I like simplicity and would like as little as possible to worry about.

We'll see what I can get done tonight! I'll try and gets some Build ACTION shots.

And it looks like a TOADIFIED norvel 061 might be in store.... well, my take on toads mods. Yum.

Here's a picture of the Rivets Rog has now. you can't see the pushrod from these. Maybe Rog can snap a photo of it.

well heres where I'm at. basically the top of the fuse is done. lotsa sanding! but thats cool forsure! Im going to have to go back to my LHS on friday to pick up some wood for the wing I forgot. and some servos, HS55's ?

vic, that cowl/scoop under the engine looks mean, I hope you dont mind if I copy it!!! also, how did you go about the dowel LE? sand a half circle in the front f the ribs? or is there a better way.

Your'e moving along well!
I use a pc of brass tube in a drill press to cut the radius.Then line all the ribs up on a small pc of spar material to sand the scallop to fit a short pc of dowel.

I know the best part of 1/2a is keeping it cheep. But, I think a piece of Carbon Fiber tube here instead of a wood dowel might be even better...

I've thought about that a few times but CF is a pain to sand vs the dowel. I also use gorilla glue for the leading edge to give me pleny of time to work before it kicks. With CF I haven't had much luck with anything but CA to glue it with.

Yeah Im not gonna lie, I wanted to go CF, but they didnt have 1/4" CF tube at my LHS, Maybe I will look harder when I go tomorrow.

What about using a Medium or thick CA that takes a bit longer to set? then you could have enough time to fiddle with the stuff. I always use a 10-15 sec medium rated CA that gives me enough time to move things a bit if Im quick, but sometimes I think its too slow! DOH'! I know they have a thick one thats 25-30 seconds to set. Either that or epoxy.

Vicman, where did you put the elev. servo in your build. Did everything fit and balance between the formers under the cockpit? And what happened to those pics you promised!


Also I need to order some receiver bats for this and my DNU, what would you recommend?

Well heres progress report number two.

The wing is basically done. It was a frustrating job I must admit, but I got it handled. The dowel LE sure feels tough! I wouldnt wanna mess with that guy. There was no centre rib in the Laser cut parts so I had to make one. am I missing something or is this correct?

Vertical stab Is mounted and the Horizontal stab is covered.

To do list is, cut out and build ailerons and linkage. mount elevator controls, servos, plank bottom of fuse and cover. I will probably get most of that done tomorrow. Maybe If I dont sleep in I can finish it!

Still waiting for a pic of that elevator control vicman.

Other then that its allllll good!!

You are correct. I left out the center rib by mistake. That's been fixed.

Vic, I thought you were going to rip open the aft end so we could take a look at how you did it? []

well i got vics kit aswell, very good little thing, only broke a rib in post all the way to australia.

ill put up only one pic of it so i dont highjack this build thread but i love the little plane (dont kill me for my power choice )
u cant see it but all i did for the elevator was glue the servo in bteween the two fuse sides right at the back instead of the balsa block and just connected it straight up to the elevator

i will also post a build thread when i get some time when a course i am doing finishes
