I`ve only read this 1 page, but I hope the Fellow that started a thread this morning ,about his LHS telling him that Castor oil was a thing of the past, and an all synthetic oil in the Glow fuel,is the way to go, reads through this Thread.He`s from Japan, I think..He`s running a High RPM, Norvel 0.061" .I`ve gotten over 21,000 Rpm [:@]out of mine, and she`s gaing RPMs still.[>:].A total of 10 ounces of fuel since new.. Here`s a chart I made up, of some testing I did,on the same type engine,a BigMIG Sport R/C 0.061".2 ounces to break it in, and the rest of the runtime, was at W.O.T. and is detailed, and recorded, on this chart..Check it out Guys ,you know, She`s got to be Hot, at these speeds ,and bolted down to a table.I also let the engine run(to get Temp.up) for a short while, before taking my readings.Unfortunately, I didn`t have a means, to measure The TEMP.[
] But I did use different types of fuel and quantitys & percentages of oil.
