Pipe for DLE 35 RA
Guys,
Thanking about putting a DLE 35 RA in a 2 meter pattern airplane. Everything I've read says it is a good setup for a pipe on the DLE's rear exhaust. What are sources for an appropriate header and pipe? Does anyone have experience with running the DLE 35 on a pipe? Help me understand.
Thanks,
Larry Fitch

RE: Pipe for DLE 35 RA
I think there are very few actually in the hands of customers and perhaps none running on a pipe yet. I asked a US importer for the exhaust port dimensions and got no response. A simple sketch like the one below is all that is needed. Until the exhaust port is known it's tough to come up with a header. Most likely [link=https://www.krumscheid-metallwaren.de/neu/showarticlelist.php?action=list&lang=EN&cat=SBS_S]KS[/link] has a header part available that is a close enough fit to work with little or no modification. You just have to sort through their many variations.

Look at my various threads on piped gasoline engine set-ups. I've writen a fair amount on the subject of adapting gas engines of this size to pattern use. You will also find soft mounting for this size engine.

RE: Pipe for DLE 35 RA
Replied your email. I never use the pipe to fit to DLE35RA and I'd like to know the result. I send you the pipe for free but Ican save the money to buy a DLE35RA for the pipe fitting result.
It is worth to me.

Got it from Troybuilt...$35.00...not bad.
It' made for a ZDZ40 Rear Exhaust and they have a straight, as well as the 25mm drop down header.
I was fully expecting to have to mill an adapter plate but it turns out that the mounting hole alignment is perfect...don't have to do anything to mount it up. May open the pipe flange a bit to more closely match that of the motor exaust port as it looks a bit restrictive.
Going to put it and a ES Composites 40cc pipe in an old Piedmont Focus II that currently has a YS140DZ in it. Need to lengthen the pipe tunnel a bit. Weight & performance should be interesting.

RE: Pipe for DLE 35 RA
So I saw the OS 140rx header will work. I am now looking for a suitable canister. Troybuilt has the jmb tr50 which is described as a tuned canister for 50cc engines. It calls for a long header. I am assuming the header coming off of a rear exhaust dl35 would be too short. Am I correct or would it be OK with the extra volume of a 50cc canister? They also make a 30cc canister but it calls for a long header as well so I am pretty sure it wouldn't work. Does anyone know of a better canister option? Preferably with a 20mm Inlet diameter to fix the 140rx header? The tr50 has a 25mm Inlet and will require a 20mm/25mm coupler. I would like whatever power increase a tuned silencer would give me but just a noise reduction would be OK as I don't have room for a full tuned pipe.

The MACS Pro product for the 140RX is the one you want. You may need to go directly to MACS Pro to get one built. While they are at it, asking them toleaveit extra long could be one answer to the long header problem.....
