June 21, 2008 - New style - Goblin Panel

Hi Robert,

I was thinking of spreading the panel laterally to reduce vertical clutter and create something in harmony with the art deco style of 1920s cockpits.

The decking curve looks much better now and with those corner blocks will be very substantial.

Your Super Goblin is going to be something very special!

Best regards,
Lynn


Thanks Lynn,

Here is an upgraded Goblin Panel with your input added. Things are not final yet but the decking curvature will be made and the rest will be thought through later on. For the rest of the group here is an attempt on the Goblin Instrument panel.

Robert


That looks excellent, Robert.

The actual stick pivot is located above the lowest point on the fuselage cross-section so the stick arc-of-travel will be greater than it appears on the cross-section.

The exposed timber blocks in the corners at the longerons could be covered with small pieces of folded aluminium screwed in place to maintain that all-metal engine-turned effect of the instrument panel. I did this on the Tigerfalk - see the diagonal block at the longeron, right hand side. Ignore the red arrow which was added some other reason!

Hi Lynn,

I added a few more circles and rectangles to the cockpit layout.

Perhaps the inclinometer could be placed at the top of the cabane just under the wing, so it will be in the line of sight at all times.

Robert


Hi,

Here is the image with the inclinometer on the forward cabane as a suggestion. Maybe a bit smaller.

Robert


Here is a panel with a smaller inclinometer at the top of the instrument panel. This one is 2.5 in by 1.125 in. This would keep it at eye level.

CAD makes it easy to work with and at the end one gets a template for the instrument panel. Just make sure to draw everything to scale, 1:1.

August 1, 2008 - Flitzer Fly-in Brodhead

Hi,

I have been having visitors from Sweden almost all July so not as much progress on the Goblin as what would have been possible.

I am currently working on the firewall. Question: Since the firewall is 1.5 inch higher than "normal" is the engine going to be located slightly higher than the normal location or should I keep the same distance from the bottom of the fuselage as on the drawing?

Also I have completed the drill/router table. It works great and save space in my one car garage or my one biplane cave.......Obviously one can not use the router and the drill press at the same time but both can share the same table. Here I am using it as a jointer (sort of).

A few LSA aircraft from the Bay Bridge Airport came and visit the Suburban Airport (in Maryland) and they took passengers up. A friend of mine and I went flying in a Sky Arrow. It was his first time flying in a small airplane. Here is a picture of the plane and him. When it was my turn I go sit in the front and flow it for some time. Nice panoramic view from the Sky Arrow, but there was one wing missing...however it is always fun to fly.

Finally back in the cave! It has been to much daylight for some time now!

Hi Robert,

It's great to see your progress on the Super Goblin in the Troll cave. And such a neat workshop!

Regarding the thrustline: it's probably not critical. If you can live with it where it is I'd leave it, but if there are some good reasons for moving it (structural or for carburettor containment within the lower cowling, for example) then by all means raise it an inch or so.

Best regards and hello to the bats,

Lynn


Thanks, Lynn.

I am locating the horizontal "beams" and may need to make a hole/'cup" in the firewall if I need to put a magneto or starter at the back of the engine. I am not going to make a hole now but be prepared if needed. So it will have 2 horizontal "beams" instead of 1. I will locate them at the engine mounts. Another question: What type of wood should it be for the engine mount reinforcement mounted to the firewall on the inside of the cockpit ? (as seen in this image of the Goblin cockpit)

The Gnome, the Goblin, the Gargoyle and the Gremlin all says hi.

August 3, 2008 - Goblin Firewall update

Hi,

Here is the Goblin firewall with some modifications.

Trying to make room for alternatives (if needed) with minimal effort.
