Re: fuselage length

So you are at 23" aft CG?
What are the min. and max. pilot weights shown on the W&B?
The wing is back 4"- does your W&B show how far back the wing LE is from the firewall?

Re: fuselage length

Tbopper; The shorter fuselage might be a bit lighter, but it won't solve the rear CG issue. Both the long and short fuselage are prone to CG issues. While it's a bit of a project to fix after the plane is finished, it can be done. You mentioned that you bought the project, was it flying when you bou...

Re: Intro questions

The plane wasn’t designed for trailering.
On the 3 piece wing, the outer wing panels are removable, but it’s not a simple project and not one you are going to want to be doing before and after each flight.

Re: Intro questions

Hi Jamie I have heard of projects being completed in as little as a year, but I think 5 is about average build time. Lots of other things do get in the way during the project! There is no really complicated woodworking in the plane, (some of the welding is more complicated than the wood work) it was...

Re: Still new and nuts on nuts

If the parts you are talking about are not rotating, then nylock or metal lock nits will work.
It would also be a good idea to add inspection panels or plates where you can so you can get to the parts and inspect them.

Re: Is this 1/8" ply required at hinges?

John, that plywood gives the fasteners a stronger surface to tighten down on.
The spruce is too soft by itself.

Re: attaching post hinge?

I am using the 100 degree cad plated screws ( I think they still have an NAS number)
I put an access panel in the tail of the fuselage, so I can get to the nuts on the backside of the tailpost,
as well as the fasteners for the vertical and horizontal stabilizers.

Re: control sticks connection (rod)

I put the rod on the other side of the control sticks and got some more room.
My hand hits my legs before the rod hits the opening.
If you put control stops in the cockpit, they will most likely stop the stick before the rod hits as well.

Re: shock struts

if your landing gear is built to plans, then, it could work. this plane had bungees and got changed over to springs. These are external springs- the spring in a can version is a bit larger so clearance might become an issue. These are a couple of images on how to make the external spring type gear. ...
