Hi all - currently building a new Rindmaster profile light for fun using a plan very kindly sent to me by Floyd Carter - Hats off to you sir 
Hopefully get it all done and dusted so I can fly in the world wide event in early October. Anyway build progressing nicely and I've recently acquired a couple of OS 25's from a clubmate for it. I'm looking to use the OS Max 25 because it's a bit lighter than the later version and it already has a stunt venturi fitted.

I wanted to use an inboard tank but I can't find a supplier for the recommended Hayes 3 oz tank. It appears that they are not available over here so is there an alternative or will any suitably sized and plumbed clunk tank do the job?

Cheers
Paul
