The development of a suitable power plant for very small model airplanes has long been the ambition of a great many model enthusiasts. To the advanced model maker there is not a more interesting and fascinating branch than that of model airplaning. The use of steam as a motive power for airplanes is, as we all know, a very old idea, having been first attempted by Stringfellow in 1846 in England, by Langley in 1896 in America, and of late years by Messrs. W. O. Manning, H. H. Groves, and V. E. Johnson in England. The experiments of these last three gentlemen, as recorded in the Model Engineer and Electrician, have been a great incentive and also exceedingly helpful and instructive to the writer in the development of the flash steam plant about to be described.
