Boy Howdy!!
I have been cogitating building a 3 for close to two years. My better half has really let me know that would not be wise until I unload one of the other planes.
I am gonna have to quit looking at Pauls posts cause they are making me want to sneak off with the checkbook and order a kit.

The only thing better than a G3X is two G3Xs!

I think that you've nailed the point there Dave - one of the things that I am finding that I find most interesting about this build is the idea that we are building a much more capable airplane than it was originally designed to be, and doing it with very little weight gain - all because of the advances in modern avionics.
Let's face it, human flight went from kitty hawk to the moon in 66 years, yet our basic airframes have now changed little in the past what, forty? The major advances in aviation have been in avionics, not aeronautics in the past several decades!
And yup - the second G3X screen really doesn't cost much once you've bought the initial package. Just think - a panel blank is only $32.....very easy to replace....scrape together the pennies, and you'll probably end up lighter than you are now!
Oh, and Milt - you can just tell her that you can fly an RV-3 for an hour on the gas that it takes to start, warm up, and taxi the Radial.....

What I'd like to know is.....
....whether or not Louise does acro. Have you given her any dual in either the Val or Mikey?
Methinks that Louise will be rather tempted to get the belly oily once Jr. flies
Best,

Hey Paul.
I notice that you have a guarded start switch on the right side of the panel.
Does this mean you're holding the stick back (tailwheel) with your knees during start?
I've been tempted to put a guarded "starter enable" switch on the panel and then a recessed "starter engage" button in a non-inadvertent place on a stick grip. That way, one hand on the throttle, one holding the stick back and engaging the starter. But I'm also cognizant of the "Adding complexity and failure modes" discussions resulting from this choice.
I know there have been lots of posts and opinions posted about holding the stick back or not... I'd like to hear your version.
Thanks in advance.

I have my start button on the stick, wired through the ignition switches and a normally-closed oil pressure switch. The starter won't activate unless I have an ignition switched on, and won't activate if there is oil pressure. This setup has worked great, but doing it again I'd probably go with a panel-mounted button just for simplicity. With proper use of the throttle I think there's little risk of nosing over during startup.

... and with improper use of the throttle, there is a risk of a noseover wherever the stick is
Also important are the brakes - ensure they are off, but covered, and a clear area ahead.

Paul, the panel looks great. I sold my 8 last year, and don't tell the wife, but I just ordered the preview plans for the 3B!!! It won't be long now till the rest is ordered and construction begins. I read on the post that you were using some CB's as switches. Just some trivia but Willie Messerschmidt did the same thing on the BF-109. I assume that with 33,000 of the type having been built that CB's work really well in place of switches in a cockpit with limited space. I can't wait to see your 3 finished. Joel McMillian

Weight ?
Just an observation, honest.
One of the great things about building is the freedom to customize and make these machines our own but isn't it interesting how acceptable it has become to build a 750lb empty,1100 lb gross wt. design, at almost 900lbs empty and pick a new gross wt. of 1300lbs...an almost 20% increase.

Keep in mind the original weighed about 690 lbs! Mine weighed the same, since it was set up exactly like the prototype, including the O-290G. Most new ones are around 800 lbs. The -3 is the plane I'd want to come back to when I get rid of the Pitts.

Our target is 800lbs basic, and constrained to a gross of 1175lb (UK). This is with IO-320, C/S Prop [has to be MT really], Inverted system. It will be a challenge, but I do know our avionics bill will be somewhat smaller than Paul's
