I have three Saito 100's and love all of them. They run inverted as well as when they are upright. They come with a 3 year warranty. You pay for what you get. I would recommend the Saito over the magnum.
Thanks Hellcat I have a Magnum 61 that runs great and also a OS 70 that runs great (after i got it adjusted) but have never owned a Saito and I want the engine that I put in this P-47 to be reliable so if the Saito is that much better and it runs good inverted then i will be happy to pay the extra $
