Making a pipe for the P20
 

Currently I am working on two P20 powered projects and required pipes for the installations, there are a few pipes about on the market but one was too short and a little heavy, and one was very expensive!
As we (Richard Chant) and myself will be launching a new composite P20 powered jet shortly it made sense to look to make some pipes for this application.
The trickiest part is the intake bell-mouth, so following a few discussions and exchange of drawings with a metal spinning company a box full of gleaming bell-mouths arrived a short while ago. I hope the stainless pipes will be here tomorrow so I can make up the finished article.
I over ordered so if anyone out there wants a pipe for the P20 just PM me for more info.

Is the pipe going to be single or doubled walled?

RE: Making a pipe for the P20
 

Single for the time being.

What it weight?
Since you said other make it heavy and expensive.
I though my 15" double wall pipe for P-20 weight 4 oz it earn the light weight champion title. I be suprise you someone can make even lighter.
Must be using TT metal to drop another 30% in weight.

If you make the material too thin you will regret it...

That why there is testing had to be done.
My had over 30 flights in the 1:12 scale F-16. It still hold up.
Goes up another .001" it not a problem and not add too much weight.
But it nice to know can do it light and get away with it.

I have around 45 flights on my Cougar now and I'm sure the small weight saving is not worth a burnt pipe! My moulded Cougar with big tailplane has no nose weight...

Tam have no experience of your P20 pipe so was not making any comparison, I know you have a good reputation and your products are excellent.
Anything made will be tested, as has been done in the past with other pipes - maybe even this week if all goes to plan and the weather behaves! The pipes are primarily for those who want to use P20 power in the new jet.
I will weigh the complete unit hopefully when the pipe sections arrive for reference.

Tam's pipes are consistent with their high quality and performance.

If he sells it, you can be certain that he has thoroughly tested it and it will perform.
