Yeah, the scale thing is an interesting compromise. All the WAR planes are too small to be practical,as well as having nasty flying habits! If built carefully, a large plane can actually be lighter than a small one. A good example of this would be the Titan T-51. Considering that it is a two seater with retracts, it still does well with only a 912. Maybe a better example could be the Leohle 5151, about the same size as the T-51, but half the weight, only single seat and only needs a 503. Not very pretty or great scale,but these are sometimes the compromise? 95:10 will never change but could be the limit of choices without going into GA experimental and the associated cost. I'm not sure where you're coming from, so cost may not be a problem? Retracts, once again 95:10 has NO rules for or against, only the weight limit. As for other RAA classes, again no rules either way.. Technam-RG, Sabre-RG, Leohle-5151, etc. Might as well keep posting here, I can find it now..... Have you ever been to; this Homebuilt site? You could get some ideas from these guys as well. As for the SR-71, did you also have a close look at; My Harvard? This is another PhotoShop job, believe me real Harvards are BIGGER! I've actually got half of that machine designed in my computer. Harvard plan. Was looking for a war bird and knew people would then ask for a two seat version so thought, 'Why not build a scale two seater in the first place!' Was designed to use a 912s, then discovered the Rotecs', but not sure if I'd use one now? Arthur.
