• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Plans built S1S,
I just about done behind the firewall.
I’m a long way from putting it on scales but thinking about CG.
Everything firewall back is pretty per plans, exception: elect fuel pump, regulator in place of wobble pump.
Earth X battery in standard location.
No canopy.
Gen 1 Sparcraft wings.

FWF- IO 360
Thinking lightweight starter
8 amp accessory mounted alternator.
Christian inv sys.

I’d rather not be faced with a big CG discrepancy on completion, trying to stay as light as possible. If I’m going to add ballast I’d rather it be something useful vs lead.

Id appreciate any thoughts or educated guesses
on where things are going to end up,
also Prop options etc..
Grateful for all the previous feedback on my newb questions.
Thanks, happy new year!
Doug

EDIT, spell check screwed up the heading to this post “CG” considerations
