Question: I have a VMAR Texan II 45-60 ARF. I'd like to mount my .46 size engine at 90 degrees and use a Pitts Style Muffler. Will this work?

Answer: Yes possibly but we would suggest an angle more like 110-140 degrees depending on your engine and muffler. This will be a matter of personal preference coupled with whatever limitations may be imposed by the muffler and the engine. The issue here is balancing the desire for a more scale like engine installation versus the scale like exhaust stacks on the cowl. If you mount your engine at 90 degrees you may (depending on the engine) have to cut into or cut away one of the scale like exhaust stacks fitted to the cowl on either side just aft of the nose ring. If you rotate your engine somewhat more (or less) than 90 degrees you can leave the exhaust stack unscathed and still achieve a good looking engine installation. Trial fittings will help you decide on what angle will give you the best overall appearance.
