• 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 $29.95/year 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).

  • If you have bought, sold or gained information from our Classifieds, please donate to Biplane Forum and give back.

This tachometer is used and is in excellent condition. I was in the process of sending it out to be zeroed out as my engine is being overhauled when I discovered there are 6 cylinder models and 4 cylinder models. This one is 6 cylinder I need 4 cyl. :((
I would like to sell it at my cost, $130. If you feel that is to much make me an offer. Does not include a wiring plug. I was going to get one from eBay as there were several listed there or directly from Horizon. I will pay shipping in continental US
Thank you,
