In the model airplane world anything with a coating on the cylinder is considered cheap. I think mostly because on model airplane engines they do the block and cylinder in one piece then coat the cylinder to get the hardness needed. It is a very cheap way of building an engine (low parts count), but is very lightweight. I still think of the Nikasil cylinder as a throw away part. It isn't shop rebuildable if damaged and new cylinders will have to be bought. I guess that makes it not so cheap. One web site did claim the Nikasil cylinder is 2-3 times stronger than chrome plated cylinders. Bottom line is any cast iron cylinder engine converted to these aluminum cylinders will be lighter weight. I may buy a set of Nikasil cylinders myself.> > Kevin.> > > > > > -----Original Message-----> From: n5...@hiwaay.net> To: kr...@mylist.net> Sent: Thu, 21 Dec 2006 3:40 PM> Subject: Re: KR> RE: Nikasil...> > > Kevin wrote:> > > I think the advantage of Nikasil cylinders is they are cheap.
