• 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.

I see on the Steen website the 540 mount with conical mounts.

I also see the 360 Lyc mount with dynafocal mounts.

What's the reason for not having the dynafocal option for the 540 being that the 540 is on many certificated airplane tight cowling installations with the dynafocal arrangements?

Is it that there's too much weight to handle with aerobatics with two extra cylinders out there?

It seems like the airplane would like much less vibration theoretically.

I know on the Aztec after a loooong time the dynafocal will start to sag the nose a little, but not a whole lot. Just means new rubbers needed.

In Steen the dynafocal 360 mount is a 100 more than the 540 conical rubber bushing type mount.

Are the bolt holes attaching it to the fuselage any bigger.

I am having to possibly order this with friends relaying me the dimensions of the bolt holes center to center and bolt hole width with me not seeing it directly in order to get it started as I am away from home for another 3 1/2 months.
