TBM Muffler Silencer for the Stock DLE-20 and DLE-35RA RC Model Gas Engine Muffler – Purchase 2 for DLE-35RA
Fits Stinger ID: 14.4mm / .57″
These silencers work very well. They decrease the noise level noticeably without compromising the top end performance or increase the cylinder head temperatures excessively. There is a loss of a few hundred rpm at full throttle. Obviously there is only a slight performance decrease, and this is only at full throttle. Most of the time, the engine is not at full throttle, so the general performance of the aircraft is not compromised much. With AMA and flying fields looking for alternative methods to lower the noise of RC planes. This is a simple alternative which is low cost and extremely easy to add compared to canister mufflers, converting to 4-stroke engines, or converting to electric engines.
Extremely easy to install, either press fit the silencer in place and then hold in place with the included silicone tubing and cable ties or drill a hole and install a screw. During our tests we did neither, it stayed in place simply by friction, so they stay in place quite easily.
Help save your fields by installing this silencer!
