Are there any tune pipes for Gas Motors ie:DLE 30?
OK, just an off the wall question, I got a sweet running DLE 30cc, and all the guys at the feild say you cant make a gas motor fast, and that I should of gotten a OS 1.60
Anyways, I know on a 18X10 I should be around 7500rpms, but I really would like to go with a 18X12.
I know I could go to a 17X12 but I belive the lose of torq will make it go slower. Its a 11 pound spitire.
So I was just wonder if there was a tune pipe for these sweet gas motors, so maybee I could run a 18X12 with out much loss of rpm vs the 18X10
My dad asked me why cant I just spike my gas with a little 15% nitro fuel, to make a little more power. But that sounds odd to me.

try the MVVS 3266 (26cc) or 3268 (35cc) pipes.
They need only short 6 - 7" headers, and the competition as of today does not know how to match their properties.

What I need is a Pitts-style wrap-around muffler that will work with the stock DLE30 standoffs. Not a whole lot of distance from the back of the cylinder cooling fins to the firewall of my ESM P-51 when using the stock standoffs...maybe 1 3/8 to 1 1/2 inches.

1. The pipe does not care what engine its on as long as its sized correctly.
2. The header and fitting the pipe to the plane is the kicker.
3. A 30cc pipe is about the size of a kids plastic bat, that's gonna look sorta funny on your Spit.

RE: Are there any tune pipes for Gas Motors ie:DLE 30?
Right, Thats crazy,
I was thinking something like the Macs Pipes,
I was thinking it would just come off the side, stright down, then angle back like Macs. That way the hole you made for the head to get cooling would also have the pipe comeing out of it, and then going back a short distance under the colw. So I guess not a complet tune pipe but more than what a pitt or stock muffler can do.
Or even make it bolt on like a pitts, come of the head, rap around, then down, but all one peace of mandural bent allummunm.
Also I guess I wanted to know if a tune pipe would even give a motor like ours a gain in performance.
And as for the bat thing, My BeeGee R3 has a cut out on the bottom of the cowl for the cansiter muffler some are useing, If you could put a pipe to fit those demintions then just come out the back/mid body vs comeing all the way back foward it make more power.
Has anyone found a muffler that make more power than stock, or are peaple paying 1/4-1/2 the cost of there motos for a muff that just sounds better?

That is what a tuned pipe looks like. And yes, if tuned well will add gobs of power. A tuned pipe however is not a simple bolt-on item that you can change to fit the plane. If not tuned to the engine and propeller, the performance may disappoint you.

Macs pipes are tuned through the pipe pipe length, something wholly controlled by the end user. There is no way any tuned pipe is going to be fit to a .60-.90 sized warbird and not completely disrupt the scale appearence. Tuned pipes are not small, short, or made invisible, which only occurs when the pipe is fit completely inside a fuselage, generally running a third or more the length of the fuselage.
About the slimmest "mufflers" one can obtain are those found with B&B Specialties, but they often make as much or more noise than no muffler at all, and have been know to rob power with some engines.

I think my tuned pipe on my ultra stick is just under 30".
The DLE-30 runs STRONG. Like TOM said, blaze a new trail. I think it will fly great with the 18x10.

I think a bud lite muffler with a header would at least give a small boost and should be easy to make. Take a look at the thread below. I am very close to getting one done for my DLE30. If it sounds ok and gives even a modest boost....I will be happy. Capt,n

Dude, your over thinking this pipe thing. You have a 11lb WARBIRD with a engine that makes 16-18lb of thrust. Its going to fly great and look great. No need to ugly up a nice looking bird with a pipe or God forbid a beer can!
Fly it, you will like it. If you need/want more upline pull, replace the 18x10 with a 19x6.

Take a length of soft copper tubing, say 1/2" to 3/4" i.d. Cut a flange to match the exhaust port. Bend tubing to desired shape, weld flange to end. Pipe complete and about the same noise level as a "muffler".
