Original-DA-70 Compact Muffler
 
We now offer these DA mufflers, due to requests from countries such as Greece, Spain, Portugal, Italy and Iceland.
The Original DA mufflers have the indisputable advantage of being simple to fit inside the cowl of ARF wood models and give a first class running performance over the entire throttle range.
Being bolted directly onto the cylinder prevents a sudden resonance induced jump in the rpm. Due to the large diameter outlet of these mufflers, the DA engines produce a very good performance without tending to overheat. Many so called Pitts style mufflers are to be strongly criticized in that they cause power loss and overheating. The DA mufflers are made of welded aluminium tubing and delivered with smoke nipples.The standard mufflers supplied with the Zenoah engines can only be describe as super quiet, after hearing the indescribable noise from a DA muffler. We vehemently advise you not to use these DA mufflers on any model flying field that is subject to noise regulations.
