VMA-P240X Texan II, Harvard II & PC9 45-60 ARF - Engine Mounting - Inverted (Semi) - Regular Muffler

Question: I have a VMAR VMA-P240X (Texan II, Harvard II & PC9) 45-60ARF. I'd like to mount my .46-52 size engine inverted and use the regular factory muffler. Will this work?

Answer: Yes, depending on the size and shape of your engine it should work. It will require more work and possibly be more difficult to operate  than an upright or 90 degree installation but it will look more "scale like".  Please note that we do not recommend a perfect 180 degree upright installation. We suggest about 160 degrees (semi-inverted) for this model. For general information about inverted engine operation please see the relateed article.
 
Please see the attached PDF drawings of a typical  engine mounted to the removeable power module firewall and of the typical cowl cutouts that go with this engine orientation. These depictions relate to a typical two stroke engine for this model. You will need to adjust the cowl cutouts for your particular engine. Note that we strongly recommend proceeding in small incremental steps when cutting cowls to fit around an engine and muffler. Don't overdo it. Go slowly in small steps and test fit frequently.
