The Twin-15 30 G-Mark finally arrived.

Beautiful little vintage engine. Checked it all out, put some plugs in it (actually some 30 year old NIP Fox plugs!), a prop and spinner and oiled it. It is actually in mint shape (well, it has never been run). I'll need to run it this spring to check real compression. At the moment, it is a little "soft" but I believe there are 3 head shims in there, one or two of which can be removed depending on fuel and plugs.

I understand it may only put out about 0.7 hp compared to a whopping 1.2 of an OS 32 SX or 1.0 of the older OS 32F, but you can't beat the "scale" twin cylinder realism!

As I was looking at it, it actually made me think of Hanno's geared dual Webra 90 rig on his TOC Dalotel...

BTW, in these photos, it is over propped with a 9x6.5. It runs best on a 9x5 (which I don't have).
