Hey guys I just finished mounting my UAT.

I just wanted to know if it looks ok in this position. I didnt have room to do much els.

This officially utilized all the space no my MD (when my RX is installed). Im wondering where to put my turbine accesories now. I think I'll make a secondary MD under the engine hatch if that sounds ok?

Thanks and happy new year, Peter

looks perfect to me.

jason

Thanks,

I also wanted to show my RX. I installed it also today. I didn't have much room for the antennas, Do they look ok like this?

The antennae that is hard to see runs parallel to the brake valve, It's about an 1/8th or so from it.

Peter

Looks good Pete.

It's up to you, but if it were mine I'd put a zip-tie around the round "neck" of the UAT instead of on top by the filler and fuel draw tank nips. In time it *may* break the airtight bond being where it is 'pulling' at the brass nuts.

You can always roll some foam around, with some of the thin foam we use on the prop jobs, the RXs take some punishment during taxi and specially during the landings, at least try no to mount it so rigid.

Happy flying [8D]

Thanks Mike, I thought of that too, I get that done.

Last I heard was you shouldn't put foam around the 6014.

It's on 2 foam feet though, It gives it some shock resistance.

Pete

I see the foam now, excellent.

can UAT ben monted inverted... with the front side in the back direction of the jet?

No, it won't purge the air out unless you fuel the plane inverted

J

you can as long as the nipples are facing UP, the cap can go to the front or back of the jet.

I've got them facing back in my A-10. Works just fine.

Pete,
The UAT is designed to be mounted in the fore or aft position. Your is clocked 90° out of rotation.
See www.bvmjets.com/accessories/uat.pdf for the instruction sheet.
Page 2, paragraph 1 describes the mounting direction.

Harley,

I can think of no reason why the UAT wouldn't work in that orientation. Please explain.

Thanks,
Joe

That's going to be a bit of a problem. []

Pete

I'm not sure about any sideways orientation issues, but my immediate concern was how tight a turn is the fuel line going to have to do ? It's hard to tell from the pic just how close the fuselage side is to the nipple on the UAT ; if you end up doing a fairly hard radius there, you might have issues with the line kinking a bit.

Gordon

Yes, The picture is somewhat decieveing. The nipple is at a lower elevation than the lip you see. At least a good 1 1/4" to make the turn.

I don't think Im going to change the orientation of the UAT, I think I'll give it a shot as is first.

Pete

Gordon,

It will work in the orientation that Pete has it installed, but you know that I always suggest reading the instructions. When all else fails..........
Mounting it fore and aft will make the supply line bend radius much larger.
My suggestion is to follow Gordon's advice, and open up the bend radius.

Some "UAT clones" are using Festo "push to install" instant fittings, but if the tubing bend radius is too short, as Gordon has suggested, the Festo can leak, sucking air into the system. The UAT is on the "suction side" of the fuel system, so usually a leak will be manifested as a stream of bubbles instead of a fuel leak or dribble.

I had that same problem on my first turbine where a Festo 6mm ball valve was installed between the header tank and the pump. The bend radius was too small, and caused an air leak into the end of the ball valve. The air leak showed up as a small stream of bubbles starting at the leaky fitting and going to the pump inlet.


Also, the use of a threaded fastener to plug the UAT fill tube can cause air to leak around the threads and into the UAT, depleting the UAT of fuel. I have seen this happen, causing a flameout, which almost resulted in a dead stick landing. Four ounces of fuel doesn't go very far.
The supplied aluminum plug works fine, but I usually use a Festo one way check valve, or a Festo ball valve to cap the fill line which simplifies refuelling.

OR, perhaps, IF the line is kinking due to the radius then you could use a brass or aluminum tube for the 90 bend portion, avoiding a re-make of the whole tray. The easiest way would br to use an aluminum 'T' fitting with on leg plugged off. Nice tight turn, no kinks.

I would use an elbow instead of a tee should you choose to retain the same UAT orientation....large bore nylon elbows are available at better auto parts stores. Safety wiring all of the connections with .020 lock wire is adviseable.

Yup, even better. I only suggested a T cus everyone has 'em and elbows are harder to find. Never considered an auto parts store tho. Duh. (forehead smaaaaaack)

Hey Don!!!....While you are smackin' your forehead give it another smack for taking so long to get this done...[sm=spinnyeyes.gif]...Hurry up so we can get some flying in!!!

Kevin

Don,
They are used in vaccum systems.........................

Thx Harley

Hi Kev, sent a PM

Hey Pete, looks good!! keep up the good work,[sm=thumbup.gif]not much room in that F-16 is there? it gets worse
