Hi all..
I have a Byron F-16
O.S. 91 ducted fan engine
Byron Fan

What pipe would be best for me?? This is my first jet and im not looking to break the sound barrier. I want a reliable setup.
Thanks AJ

Weston. Hands-down. The best.

are there diff types of weston pipes for the OS 91??

Try a #5 Byron with the Rossi offset header. Use the BVM header adapter on the engine. Also use the BVM pipe retainer on the Rossi header. Use a white Rossi Pipe coupler and BVM hot seals between the pipe adapter and header.

Complicated but very reliable!

Let me know if you need more info.
Good luck with whatever route you choose! The F-16 is a great plane! Make sure your tail is in satisfactory condition! Do a search to find all the different mods.

Dustin,
You lost me at "Hello"! LOL
The weston seems very reliable and simple.. from what ive been reading.. found a pic of one with a dual exhaust.. is that one i can use?

There are tractor and pusher versions of the weston. Twin outlet or single, too, I think.
JD enterprises sells them here in the US, he'll set you up...
It's soooo simple. No pipe hanger required, either. Plus it takes up a LOT less volume in the fuse, easier to put other stuff around it, and better airflow.

My setup is pretty complicated. I only stumbled on it after years of fiddling and some help full advise. If your really interested in trying mine, call me! First you would have to find a Byron #5 pipe.
If you want I could pull the plane out of winter storage and take some pics.

Ive never used a Weston pipe, but if the guys at TGA use them, they probably work! You could probably call Steve at TGA and get the real deal on what to run. He should know a little something about the Byron F-16. He would probably help you out even though he dosen't sell the plane.
(I am asuming they sell these pipes or have used them, just a place to start.)

Im sure you will get all sorts of answers that all work. The problem is the offset needed to clear the nose gear with a long pipe.

Good Luck!
Dustin

TGA would sell you...a TGA pipe! Theirs is good too, but the advantage of the weston is it is much smaller and needs no pipe hangar at all. The TGA one is also pre-tuned, and seals in a similar way. Price is about the same for both, but I think the weston is better, for sure.
If I had the TGA sitting around, I would use it, but if I was about to buy a new pipe(I am, actually!) I would get another weston.
Sounds like your solution is the way to go if you have a byron #5, though, and you want to use it.

The weston is a great set up for the f-16. When I built mine, I mounted the front retract in a ply tray to the bottom of the air ducting. A 1/2 diameter dowel sits just above the retract body and keeps the fuselage from absorbing the shock when landing. A robart strut is attached to the retract wire. Nice thing about this set up is my front gear is much shorter and mine tracks very smoothly down the runway without the byron boogie effect. Bad thing about the weston on the F-16 that I ran into is using spring air retracts. The two outlet pipe blows the hot fuel residue on my retract cylinders and it shrunk the o rings in the cylinders. Good thing they were spring air. I now rotate the pipe so that the outlets avoid direct contact with the retract mechanism. I can provide a picture of my front gear set-up for anyone that would like to see it. Jim

Hey EASYTIGER, I was talking with Darrell at TGA last week about their pipes. from what I understand they have a new short tuned pipe that gives you more room in the fuse.

Check it out on this link and let me know what you think:

I was planning on running this pipe on my OS91 with Byron fan in a TGA F15.

Here's the link for Weston pipes. It shows trackers and pusher pipes and you can see how short they are.

TGA's "New, Shorter, Tractor pipe" looks like a Weston, to me....

if you go with the byron or TGA pipe that is telescopic and adjustable, you may need to lengthen it to about 1" longer than the 12 1/2 ?? inches they call for. I was getting lean runs, blown plugs, loose head bolts and loss of power and couldnt figure it out, "it was my first DF" then a friend from atlanta told me to lengthen the pipe to 13 1/2 based on his experience. IT WORKED, from that day on with no more problems. Also get the JMP System 1 o-rings that are WHITE , they will last twice as many flights as the red. I always changed my plug after 3 flights and my o-ring after 6. Probably could have gotten away with more but they are cheap parts. russ

It sure is! Just proving, if you can't beat them, join them!

YES! after reading some more post i remember this was a problem for me too, the TGA pipe i had was a little too long for the byron F-16 and it would hit the nose gear when you retracted it. I fixed the problem by offseting the heade a bit more than it is designed to be but a shorter pipe may be a better fix. rus

FYI

TGA does sell the Weston pipe for Byron type applications.
I purchased one from them for pusher type set up with the O.S. .91 and it works great. Light weight, easy attachment. You can't beat it. They had quite a few in stock and they can answer any questions you may have. 1 815 433-6132, www.tgajets.com

I'm building a Byroblaster Enforcer. Although I already have a TGA pipe for it I am considering getting a Weston pipe for less weight and less modification to the fuse.

I'd appreciate hearing from anyone that has put a number of flights on a Weston/Byron pipe. My concern is the springs that attach the pipe and how well they might hold up under extended use with all the vibration, etc. The spring wire diameter is quite small as well as the holes in the pipe flange that they go into. I've seen some Weston pipes where the springs will enlarge the holes and wear into the aluminum pipe flange.

Will the pipe and springs hold up?
Will the pipe start to sag after a while and not provide a good seal at the header ?
