OMI Fuel Magnet in Turbine
Has anyone tried using an OMI fuel magnet in a turbine? I've just ordered one for one of my Nitro machines and wondered if it would work on a turbine. I guess in theory it would work and would illiminate the need for a header tank but is it suitable for use in Kerosene?

Hey,

I dont think it will last long in the kerosene like you say, they dont last to long in IC machines with the exhaust venting into the tank from what I have heard.

I to have just fitted one to my F3C Predator and it works a treat.

From what I remember I think WREN are able to supply something similar to this, in clunk style for turbines. Again working on a similar principle to the fuel magnet & UAT, but as a clunk.

Perhaps a quick call or email to them will reveal what they can do for you.

Hi Ian,

I've got the standard Dubro felt type clunk in mine from Wren, I just wondered if there was anything better out there so I could do away with my header tank completely to save a bit of space and weight.

I figured that anything that is OK in Glo-fuel would probably get destroyed rapidly in Kerosene.

Hey,

Yeah, like you say kero destroys quite a few materials very quickly and I think the OMI foam will soon melt away

On my model I'm still using a stock clunk I think but with a UAT fo the bubbles and it works well, although the UAT's are not cheap.

I think WREN can make some kind of tank clunk with similar material to the UAT, I seem to remember talking to them about some nice clunk they can make up. But I have not pursued it further yet as my setup works a treat.

I heard that the UAT's were not that reliable so instead have two header tanks - more capacity, and makes the model look more symmetrical with one either side! Never seem to have any air at all in the second header tank even after throwing it about the sky!

RockDoc, sorry buddy but you have recieved the wrong info on the UAT.
The UAT works extremely well and as advertised, they eliminate any air bubbles from entering your turbine. 60.00 is a small price to pay to ensure that your fuel system is bubble free. what is an additional 60.00 when you are flying a 6 to 8K machine!!!!

Hey RockDoc,

WREN are not great fans of the UAT's, prefering to use normal type header tanks with a 4mm outlet.
However as optikaman said they are proving to be very good, all the jet guys use them due to their good service. Plus for the cost of a UAT compared to a model I can justify that.

I am using one on my Predator Turbine purely because I know they work well and at 8 foot inverted with a heli a flame out is not a good thing to have happen. Mike bailey gave me one 2+ years ago now to try and I haven't stopped using them.
To start with once first fitted the first few flights run a risk of a flame, due to purging all the air out of the UAT membrane. With the plank guys it's easier as they run at full power for X time and if there is a bubble present it leave the tank while on the ground.
Heli's are a bit more difficult, I keep it high and close in the first aerobatic flight after fitting a UAT.

Just as a small side piece, last year when I wanted to replace mine to be on the safe side I spoke to Dave Wilshere to see about a spare membrane. He told me that he has one in one of his which has been in there for over 3 years now without problem.
I changed it anyway to be safe

Hi

Just my two cents. I just use the felt clunk supplied by wren, no header tanks, no UAT's and no trouble for a few years now. Always told to keep it simple. I believe thats common knowledge and works just fine for all the turbine heli pilots here In Perth.
In saying that though, It depends how hard you shake your turbine heli up to create bubbles, I fly scale and barely produce a ripple in the tank let alone a bubble and secondly 99% of my fuel filtering is done prior to fueling the machine, so a felt filter clunk Is more than adequate.

I 'shake' mine around a fair bit more than you would with a scale machine but having said that so far with twin header tanks and the felt clunk I haven't had a flame-out. Just a couple of engine shutdowns which I have yet to get to the bottom off.

Was talking to Sara and Roger at the 3D Masters at the weekend and got a couple of things to try. They are also going to send me a download lead so we can look at the last data and try and work out why.

Ian, why does Wren actively dissuade the use of a UAT? Do they feel there is something inherently bad with them?

I have a UAT in my Bergen with the Wren and although I do not have a lot of time on it yet( 5hrs+) I have had no problems with flame outs. Craig

Initially we had reservations about UATs because some people seemed to have problems with them, but now it comes down to personal preference. Some people use them, others use header tanks. Some people feel that they can cause problems, others swear by them. We've got satisfied customers both with and without UATs.

Hey Nick,

I see Sara has already answered for WREN above.

All I know is that with a turbine powered model I'd use a UAT based on what I have learnt since getting involved with the turbines.
They are by no means cheap, but a good safety measure.
