Festo in line fuel filter
Nick Got a part No or photo, I thought the Festo fittings were designed for comressed air /gas use, although they work very well for us

Nick,
Haven't started using them as of yet (I assume you are talking about the new clear ones with the "screw-on" ends), however I ordered three of each size from Dreamworks RC. In talking to Todd at Dreamworks, the fixed-wing guys are pretty high on them. I plan to give them a try on the Wrens. In talking to Al at Starwood (US Jaka representative), since the Jaka's are "low volume" fuel engines, Jaka does not recommend using any inline filters. As Jack said, filter at the fueler and use a felt pick-up clunk, so no inlines used on my Jaka.

I like the visibility factor on the new Festo filters and yes, I plan to use them on the Wrens.

In line filters
in the early days a lot of problems were caused by too many in line filters, better to do most of your filtration before you fuel up, then have the inline filters before your cut off valves

Guys, I should have included a link with more info.

http://dreamworksrc.com/catalog/adv...amp;x=0&y=0

As Doc mentioned, they are currently available from DreamworksRC and perhaps any other place that sells FESTO stuff. I just got an e.mail from Todd at DreamworksRC and he confirmed to me that the filters are totally sealed and intended to be discarded when sufficiently clogged.

Doc, I too really like the fact they are crystal clear and a great place to quickly monitor fuel flow at a glance. I also like that they are totally sealed with no threads or o-ring to wory about. Glad to hear the fixed-wing guys have embraced them. I've already tried it out a few times when I tested the PHT3 with the kero-starter but had not really heard about them until very recently when I saw them on the Dreamworks web site. So far it's a perfect little filter.

Jack & Peter, so true about the merits of keeping things clean from the get go. I'm in good shape there. What's interesting to me is that during all of my bench test runs of the PHT3 I've always had a PC connected to the GSU to better monitor what's going on and I'm amazed at how little the fuel pump actually has to work, i.e. incredibly small voltages.

All of this stuff is just so cool.

Nick,
I just found out how critical the tolerances are on those little suckers too....and, as I was glad to hear they are considered repairable. Don't know what the problem with mine is, however, in talking to Al, he indicated they are definitely repairable and, I think he said the clearance is like .005. They are indeed precision little fellows.

Pump voltages
Nick
If you are monitoring your pump voltages and they begin to rise it is the first sign of a problem in the fuel system, I am talking big rises, a partially blocked filter can draw in the extreem 4 volts and still deliver sufficient fuel to fly, it is why I monitor my last flight of the day

Thanks for that insight, Peter. I will be sure to make a habit of checking the fuel pump voltage regularly.

Pump voltage
Why are you measuring pump voltage should'nt it be current as this rises with load.

Pump voltage
XXXX XXXXX
With a JetCat Ground support handset ( this is what Nick has)it is possible to monitor Max,Min and Average, Pump voltages,Temperature, and a whole mess of other things the thing which should remain fairly constant is the pump start voltage, if this starts to get high its an indication something Is not right, and by regular checking as I said the last flight of the day you can monitor, all your parameters, Early maintenence of your fuel pump can save the cost of a new one,as Wolfdad has found out

Thanks Greg
For explaining it clearly and in depth i fully understand why you monitor voltage and not current now thanks again.
PS sorry to see your leaveing.
