To Bench Test or Not?
New at Gas Engines; I have a Revolution 50 to go in a TF GS P-51; I have always ''Bench Tested/Break In'' my Glow Engines using an Engine Stand, I have a great Test Stand from PSP which is capably of Bench testing gas Engines; but I have heard different opinions, some say ''Bench Test'' others say ''run them on the plane only''; which is it, or what is your method and opinion?
