LT, How's this?

That's pretty ironic RV, I put a Z bend in and put on a Metal Arm You are probably correct about the Nylon arm.

rv9, I sent you a PM. Dan.

My control pushrods on the rest of the plane will be Carbon Fiber so I will order the connecters to do the throttle linkage out of carbon fiber as well.

Dan, your PM has been answered

Ron,

You might want to check but I think carbon fiber may also be a conductor. As close as you are Sullivan type pushrods (tube within a tube) may work for you.

Hey Ron, I like the direct connection (one, actually two less failure points) but I agree that a heavy duty nylon servo arm would insulate the servo from any metal to metal RF problems. I will get some pictures of my attempt at scale flaps and ailerons try to post them soon.

I Have some sullivan rod lying around I will see what I can come up with.

This is my first attempt at a "scale" plane. I might enter a Scale Masters event this summer so I thought that I would try to do some the the full scale details. I found a full scale Supercub that I could go and take a bunch of photos of and I bought a set of the complete factory drawing from Northland Aircraft. Using the full scale flap drawing I redrew the BUSA flaps so that I could use the full scale type of hinges in the scale location. The plane I am copying is a PA-18A model. This was a factory cropduster and for ease of loading the hopper Piper made the back fuselage deck flat. I have modified my fuse accordingly.

Is that an unstatement? Very slow, wonder what's going on?

roncannell

LT, the scale Flaps are very cool, you need to be sharing this build more often with us.

Did you put a doubler inside your back glass frame? I thought about doing this. I would like to hear your thoughts on that.

roncannell

Tony, I read a post last week that the site managers are getting ready to re-launch RCU and that alot of the original work was just patched together. So the RCU I.T. folks are trying to clean up errors and thus creating new problems. The post said another couple months and it should be better than ever.

For those of you Building this same project please feel free to post your Pictures and Progress here. I really enjoy seeing the different approaches to finishing this Kit.

Thanks Ron, I'll post some more pictures when I get the scale linkages and hinges made up. For the back window I used a dremel attachment to make a 'trench' 1/64" deep and about 3/8" wide on the outside of the window frame. I cut some 1/64" ply to fit in this trench and it projects 3/32" out past the lite-ply frame. The plastic window will glue onto the back of the 1/64" ply flange. This way the back window glass will look just like the side windows (which use a 1/64" ply flange). This will also simulate the full scale window frame which uses a metal channel for the back window.

Looks Great LT, nice work.

roncannell

messed up on my measurement for throttle location. Filled the hole with dowel and used expanding glue.

Hatch: I built my hatch lid this morning. Laminated Balsa with light ply.

roncannell

Not sure i I will use a hinge and magnets or just magnets

roncannell

Jerry, here are the detail pics of the Robart gear. The gear is 7 1/2 inches wide.

The fuselage is getting a little awkward to move around without dinging somthing. After the tail group is on I think I will build a rotating stand. I got the Idea from Tony Hallo. Pictures were hijacked from his thread.

Look at these bungee covers!

I'm following your build with a lot of interest.  I've started on one also.

Bob, thanks for the link, I have not seen this site. Are you building the 1/3 J3 or the Super Cub?

rv9-a

Thats the way it is done for a full scale plane. I used an engine stand on the forward end of my Piper Clipper when I recovered it. 360 degrees of rotation.

Hi Ron:
I'm bulding the Balsa USA Super Cubslowly!
Iused those covers on my 1/4 scale J3 and they looked great.
Spend some time exploring "The Cub Den", it's avery informativesite.

Rudder Servo Location: I made an educated guess that I will need tail weight with the GT 80 Twin engine so I decided on mounting the rudder servo near the tail. I will build a bottom hatch for access.
