Hi, I was contemplating getting a 2 metre Spitfire and a 35cc DLE for it ^-^ , however after flying my DLE 20cc after my OS .80 four stroke Hurricane, I decided that it would be too noisy and didn't go ahead with it. :embarassed:
 'But' now I have come up with the idea  :co of fixing 'back to back' another 20cc RA exhaust on my ME 109 and see what it sounds like, Has anyone tried this ?.

Yes, I did this on a ST90 powered MR Hurricane many years ago. A header to a silencer and a pipe to a home made can in the fuselage. It was whisper quiet. The DLE is a good make of engine, but the 'silencers' are rubbish. You will lose a bit of power, but that is a powerful engine. Incidentally, after market cans are available, try Just Engines.

More silencer volume should reduce the noise. I've bought one of these to try on my DLA32cc https://www.ebay.co.uk/itm/Stainless-Steel-Silencer-Gas-Engine-Exhaust-Pipe-for-RC-Boat/192834998983?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D20190606144518%26meid%3D11c94d92a0ca4c9d85712e12acce304a%26pid%3D101072%26rk%3D2%26rkt%3D12%26sd%3D183310443634%26itm%3D192834998983%26pmt%3D0%26noa%3D1%26pg%3D2546172&_trksid=p2546172.c101072.m2109

But for now I've gone back to glow with a Laser 150!

PIF, it should give you a clue. You should have googled instead of complaining. I did and it showed the item at £8.68.
Has CS gone out the window?

flying's easy - it's getting it back down in one piece that's the hard part

paulinfrance

So I suppose that this is a PIF ?,

 I will order one ( or two ) and see how they go,,
 thanks to both.
