I have an fp40 to use in my Oriental when it's finished in a couple of months, but the spraybar is bent. Where should I shop for an OEM spraybar? The needle looks straight, but if a needle isn't part of the package, I should get one too.
Thanks.

OS Part No 2231 1000 the full needle valve and spray bar assembly. Tower has them for $13.49 each with quantity discount.

Hi Ty. Are there some modifications I need to do to make it fit? Just curious, not shying away, as I'm capable of that sort of thing. What sort of "better" would I see from Randy's; more accurate settings, holding a setting more reliably, etc? I'm all for that. It's enough learning to stunt consistently without having to unnecessarily fiddle, guess, and hope with an engine. So far I really do like the two FPs I'm flying, a 35 and a 40. And I also have an fp 25 for the Skyray I'm building, but it has an RC carb. I'll address that when the time comes, probably in a few weeks.
Thanks,
Rusty

Good point Aki.

The large venturi sold by Tower for the LA 46 is 7.1 mm. Also, for reference, the PA, ST and Brodak NVAs are all 4mm dia while the factory OS assembly is 3.5mm dia.

Thanks for telling me about this. Since I'm still in the Beginner stunt stage, and not competing with this Oriental yet, I think I'll go with the OEM direct replacement at least for now.

Hi Rusty,

For now, the OEM part might be best.  The needle has a spring arm instead of being a solid bar.  If the model ever hits terra firma inverted, the spring usually bends where the solid needle will break.  No change to the case to install, etc..  After a while, the PA NVA will become desirable.

I agree, Bill.
Back in July when I first began learning PA, one lesson dogged me, and I finally learned almost too late, just get an engine run that I can work with, fly and concentrate on the pattern. I wasted so many practices fiddling with all the complicated things I read the "experts" and experts talking about. Much of which will matter, but not until I get there. I ain't there yet. But I can chuck an off the shelf NV in the engine and fly without busting a short pattern, and then some if I treat myself to a bit of extra fuel.

When I'm ready to press that engine into service, I'll PM Randy and get the lowdown on it. Thanks for the replies.
