Use the bits that cymaz's link refers to.nearly all of the so called silencers sold don't silence but merely direct the sound. The inserts do quieten the exhaust quite a bit. I have made some and fitted them to a Dle 30 and a Rcgf 15cc they work OK with only a small Loo's of power.

John,

this is really difficult and many manufactures don't show comparative noise reductions, say same engine, same prop with standard and their exhuast fitted.

a couple i have found works.

i have a BCM inverted fitted on my 1/4 scale Nieuport. that is very effective. engine is RCGF 26cc, which has the same bolt mount dimensions as the dle20.

i have an OS 22GT and the supplied wrap around OS muffler is superb. i think its the same mount dimensions (check) and you can buy them seperate. i have also heard many people find sucess with the wrap around evolution muffler

Cheers Chris, yes some are not very good on noise reduction, the J Tech has a good name though I believe.
