Tee Dee .049/.051 tuned pipe?

Tee Dee .049/.051 tuned pipe?
I'm currently in the plannig stages of a Tee Dee .049 hydroplane project. The project is in need of a tuned pipe exhast system. I've searched CEF for info and found a thread stated by Ken, but the pictures are not linked to the thread anymore. Anyone have pictures or info of a tuned pipe? Preformance results? Know where I can find one or how to make one?
I have some friends who race boats and they think this is a good project, but think the little engine needs a pipe.
Thanks
Guys

Re: Tee Dee .049/.051 tuned pipe?
There was a guy selling carbon fiber tuned pipes on ebay a while back for Cox. I don't have a link to the seller though. You might be able to make one from a Cox GTP Nissan Maples throttle exhaust collector and then need to just find a small tuned pipe and couple with silicone tubing.

Re: Tee Dee .049/.051 tuned pipe?
Awhile back Servimg (which is owned by the company that hosts this forum) had a problem where pictures were lost. I used Google image search to bring up some of the missing pictures (which I replaced on the thread). Ken would have to reupload the rest of them though https://www.coxengineforum.com/t2096-tee-dee-049-on-a-pipe

You can take a candle stick reshape to the size pipe you want and pull carbon sock over per this pic. Once the resin is cured just heat up with a hot air gun and let the wax drip out the header pipe side into a throw away paper cup.

Re: Tee Dee .049/.051 tuned pipe?
Yes just use high heat resin / hardener the pipe gets oil spray inside actually helps keep things cooler. You can fabricate a
separate header / sleeve over the cox cylinder set up to block one exhaust port. Take note not to use an SPI cylinder.
I haven't made one myself but about 5 months back I bought two sizes in the carbon sock out of Canada before the shipping
prices went through the roof. I want to fabricate a 7in pipe for the TD .020. For .049 engines you need 11in from the
start of the stinger to the piston face. You want to use a silicon coupler so you can adjust at the header to tune the
engine to the prop. 22.5k static tuned to 25k in the air is the max you can go to safe guard the ball socket and rod. Providing
you are not pulling around a heavy plane. If the plane is more than 16oz you can not exceed 24k without risk to the engine.
Ideal target range for a piped 1/2A is 8oz to 12oz RTF.
Now for boat use the loads are different. You can needle to 25k static use a RC carb as throttle is an absolute must with boats.
When starting up you want to keep the rpm down till it hits the water and rap small metal tube around the head for water cooling.

Re: Tee Dee .049/.051 tuned pipe?
@1/2A Nut
I want to build 2 pipes for a TeeDee .05 and .02 KillerPeeWee as described.
Can you please give me the exact dimensions you determined in millimeters for the construction of the wax molds?
Or maybe you still have drawings.
The carbon sock is so expensive that I don't want to build anything for the garbage.
Thanks in advance
Emanuel

Hi Emanuel,
This is a older thread my last response was in 2015, I have some updates.
Search and buy a Profi .8cc Tuned Pipe.
http://www.hobbyclub.com/index.php?main_page=product_info&products_id=1803&zenid=e850f369cfd563d802b6a591886c4cbe
I have 7 of these pipes two on boats 1 for bench testing engines and the others are on planes.
Study the shape and why it is proportioned that way it is. The shape can be reduced in size and
constructed in carbon fiber tube. The tube comes in small rolls different diameters and thicknesses,
ready to be stretched over a mold and layed up with high temp epoxy. I have two sizes in carbon tube sock
it was cheap in small 3ft. rolls.

Re: Tee Dee .049/.051 tuned pipe?
Thanks for the answer,
I've been watching your videos for a while. I like them very much
Apart from the dealer in the USA, I have not seen these pipes anywhere.
But importing from the USA is no longer possible, the tax has become too high plus shipping costs I come to around $ 180.
The only option for me is to build it myself.
But I can't do that without exact measurements.
I need a drawing like the one in the appendix but with millimeters for .05/.049 and .02

Re: Tee Dee .049/.051 tuned pipe?
Thank you glad you have enjoyed. Here is the .8cc measurements
You need to reduce down for volume .35 cc from there you will need a MRP mean reflective point
for required rpm per prop and plane type. This will allow you to have the correct pipe length
when you do the final design.
When I get a moment there is another photo I have for .010 and .020 engines.

Re: Tee Dee .049/.051 tuned pipe?
Note understanding pipes / a longer stinger will help back pressure and retain more heat for cool weather flying.
A airborn pipe cools and increases wave cycle time making a MRP longer in duration. Cowled pipe will stabilize
internal gas temp / or rap. Just factor in cooling loss when selecting props.
TD .051
Example 1
HQ 4x4.5 / 8.1oz RTF
Peak 33,100 rpm / 141 mph pitch speed reached down wind pass
Static 25.8k rpm / 110 mph pitch speed
MRP 7.5
Example 2
APC 4.3 x 5.5N / 8.1oz RTF
Peak: 28,181 rpm / 147 mph PS / 143 mph per doppler down wind pass
Best static 21,962 rpm / 115 mph pitch speed
MRP 7.5"

Re: Tee Dee .049/.051 tuned pipe?
The .15 size FAI speed pipes have interchangeable tips with different sizes. Some are 4mm and up. A smaller size gets on the pipe easier, but it can overheat easier.

Re: Tee Dee .049/.051 tuned pipe?
This is feasible once unloaded in the air, the rpm will sync to the pipe length well.
Slow NV peaking to avoid a lean out to a rare engine.

Kamtechnik Nelson Plug adapter test / Piped 1996 Killer Bee .049
APC 4.6x3 prop / best static 22,609 / 10.4oz thrust / 64 mph PS
.111hp - 82w / if this prop is used to fly it will unload and stage
on the pipe likely boost to unload at 27.5 -28k / 80mph PS

David, I think you have to load your video on to Utube and then copy/paste. I did it once from Facebook and it worked the same way. I did not have a Utube account yet. Still have not made any videos on Utbe yet, but likely will some day.
