Marty, I may be making a couple assumptions, so correct me if I'm wrong. It sounds like this is just a VW type 1 engine you have found, not really set up for aviation use in any way. If that is correct, it will need to be modified to install a prop at the minimum. I suggest you look and start researching this on the Great Planes web site at http://www.greatplainsas.com/ . There are books/manuals you can purchase on the process to modify the engine. I would not attempt this however if you have no experience working on engines. The stock engine will have a cast crank which is more prone to breaking than the forged cranks available for these engines, once again see the Great Plains web site for more info. The best VW engines to install in a KR come with forged cranks and an additional bear area up front for the prop hub. Revmaster and Great Planes are the best engines in my opinion. I have not seen a lot of redrives or rear drives on these engines, but that does not mean it can't be done. No - safety factor does not increase with redrive, it is one more item that can break. Direct drives are very reliable.

I know that if you use a redrive there is a weight penalty. But does the safety factor go up as well. I have found a 1776 cc VW engine real cheap. It is brand new and has been pickled and sitting for about 8 years. The lady wants $250. With that in mind, would the redrive be a good idea. I think I would like to buy the engine if anyone can tell me of a redrive and their performance and safety.
