It will certainly reduce the chance of air into the hopper from the fuel pick up point of view. Problem is number of tanks and amount of tubing that can add to the restriction and chance of joint airleak.
If you use suitable tubing size (inside the tank and connecting) then its fine

The CARF clunk changed a couple of years ago and should not be used on anything other than a P-20!
The internal hole reduced in size (it can be drilled out to 2.7mm) and then it works. The clunks we have made have even larger holes, but there is no US source

So how do they justify still shipping a clunk that "should not be used" in this jet? I drilled mine out on your advice, hopefully will not have issues, but...

Test flew the camo UF today at PMFC. Wet longish grass and 2-3mph wind not down the strip and it showed again why the UF is king of sports jets.
Two peeps of up trim (fractionally nose heavy) was all it needed, flap mix etc was perfect straight off.

The camo looks great. Was visabilty an issue during flight? Or in other words, did the camo work?

Thanks, Dave. The scheme alone makes me want another UF.

These photos motivated me to get another UF in the same scheme.

What's the consensus on the Dreamworks electric gear? My UF arrives next week and is like to order gear before it gets here.

Nothing personal against the op, this is 5years ago, but it's funny how things have changed. Every jet I've seen the past year had electric retracts....

Never say never.

Is that electrical tape holding the servo lines to the side of the fuse? Looks light and neat.....

Yes. I wrap the wire three times, then use ZAP20 (Slo Zap) to tack glue the tape down. If you need to lift the wire, pull and it takes a spot layer of the tape away-add a new dab of glue and re attach.
It was the lightest method I could come up with

Hi to all,
Continuing with my lovely UltraFlash, it's really the best sport jet all around. Love she.

I am building or I should putting together my first ultra flash and it's been going together ok with the help of the directions and a post I put up a couple of weeks ago on the nose gear using prolinks and it worked out well with help from other people who have put them together and posted some pictures.
My new issue is that I am using a P140 rxi turbine and I just can't seem to find the proper mounting position to run the plug through the bypass and fuel line . I am using the complete bypass with jetech saddle tanks that were made 3/8" smaller to fit better in fuse. If anybody is using this set up and have some pictures it would be helpful if you can post them and give me a couple of suggestions. I already tried mounting plug on each side of bypass but due to that 90 degree bend in plug its in the way of the saddle tanks. I fly well but never put anything new together. Always bought used jets.
thanks
