Exhaust, 2-Piece AUD0051
Looking for the most powerful exhaust system? This isn't what you want because it's optimized to be quieter, instead. It uses castings because the walls are thicker than an exhaust made with thin-wall tubing.
Add to it, the cast alloy surface is rougher, which harnesses physics again because the surface reflects more angles, thus consuming more sonic energy. All this and quiet, too? Win-win!
Who cares about more quiet operations?
You if you operate out of a noise sensitive environment! And while everything about the design is optimized toward noise control, its deceptively sophisticated.
More quiet
For example, easy access to the interior opens an avenue to experimenting for fun. Like using either fiberglass or steel wool packing materials (similar to motorcycle and automotive exhaust systems) to further reduce sound levels.
Cleaner model
Then there's the bonus, which is the downward pointing exhaust stream goes away from the model, so it stays cleaner! And whilst in the hover, being aimed at the ground makes it more quiet in operation, also.
RPM range
What it's not, however, is the best exhaust system for performing 3D-maneuvers (where the main rotor is screaming at 2300RPM). This, because the system is optimized for sport performance. Means best practice involves ops with the main rotor in the range of 1500-1650RPM, instead.
Executive summary
While this one is ideal for hovering in close quarters because it's quiet, it lends itself well to sport maneuvers like loops, rolls, and inverted flight with a more subdued note.
Of course if a louder (more powerful) more free flow system better suits your objective, we offer a nice alternative in the ProModeler ProPipev3. Or if money is no object, then the OS MAX Powerboost, also.
What comes with it?
Supplied with mounting bolts, the best part? We got a great deal from the foundry, so we've passed the savings on to help you hold down costs until your skills develop to require the added boost of power from a ProPipev3. Then, just two bolts and you're in business!
ProTip: when installing, use a thin smear of JB Weld epoxy on the flange to seal it to the engine's exhaust port. But keep it really thin to minimize ooze when snugging up the bolts. And don't worry, when it's time to disassemble, after removing the mounting bolts, just reverse a screwdriver and use the plastic handle as a hammer to rap the side of the muffler. A sharp hit sees it break off cleanly. Afterward, use a single edge razor blade to clean off the old seal, and you're ready to re-apply epoxy to seal it again. Works, trust us!
