Thanks, my friend found one.

Jim…Which scheme did you get and what power plant …. May have an M122NG available if you need ..

I already have my turbine in the plane...but the news of a Xicoy 180 has me in doubt.

I'm a power addict. I know the UF will fly just fine on a 140...but the idea of slipping in a 180 at just about the same weight is real tempting.

LA Jet guy may put a 180 in his too. He abides to no limit for power (rip the wings off, David)

LA jetguy

My new X180 should be arriving soon (I’m part of the first dedicated batch)…. I will have the X180 in the UF and initially adjust the power to 150N…. I will gradually increase power to Full over time….

Hopefully wings stay on …..

We have flown the UF for years with a JetCat P-180Rx, normal sense says it’s fine if you fly it smoothly. Also since the popular JetCat P-130Rx is 155N you can easily start there…

LA jetguy

The beauty of Xicoy turbines is that you can scale them down…. I will start at 150N and move up to 180N. All can be adjusted from GSU..

Same as JetCat…3 seconds to adjust power

Never saw a sport jet with huge range in what turbine power you can use without many disadvantages. There is video on YT showing it been flown with a 85N turbine.

The Flash series is amazing, we had one with a P-60 a few years back, it would only take off our 360’ grass strip when there was a 7+mph wind and the first circuit was slow, but once it got on the ‘step’ it was surprisingly OK. Short flight times because he was full power most of the flight but it got him to where he could afford a bigger turbine.
Anything 120-150N is the perfect combo for most pilots, so it does not runaway with them.

Dave Wilshere - how do you connect the wires between the fuselage & wing?

Dave Wilshere

The retracts/Brakes are on an 8pin MPX type connector. Because of my phobia of single point failures I use four std servo lead connectors for Ail/Flap

Hey Evo guys, can someone please measure the new intake length from the front pin mounting hole for the wing to where the intake ends. I’m thinking of converting a Gen 2 UF fuse tank area to an Evo fuse tank area and I’ll have to cut the Gen 2 intakes back to fit the Evo tank in there. I’m building a new Gen 2 UF now and gonna use a Evo fuse tank and also take out the battery pockets. Thank you!

Around 10mm - 3/8”

thank you Mr. Dave!!

Dave Wilshere

It is cut to a very slight angle, the inner wall is the 10mm, the outer edge 7mm.

My Xicoy X180 is on it way and soon be installed in my UF evo …

Not sure I ever posted install pictures of the final layout.

737Driver

wow Dave!!! Thank you so much for the detailed photo of the intakes!!! I thought I had taken those photos, but guess not! LUV your equip tray layout, very tidy and neat!!!

Looks mint Dave W. Question- Whats stopping the front of your fuel tank from advancing FWD? No ply bracing with 2x screws like the earlier version of the UF/Flash for tank installations?

Thanks!

Dave Wilshere

Under the red Velcro strap there is the opposite Velcro type glued to the tank. Then at the front the black Velcro rectangle is stuck to the wood support and tank, that is mainly to stop the front moving side to side-but helps also with fore/aft location

Question
i'm about to instal the servo's in my wing
if i hook up the aileron to my servo and if i power the servo and move it it tends to twist my servo arm.
Does anybody else have this problem?
or should i use an alu servo arm with a ball link
And what kind of brand of ballinks does carf use?
regards peter

‘The servo is not align with the Surface horn…..used a metal arm…especially this high speed jet, and use a balllink that’s what I did on the one I build, the hinge will loosen all by herself with used…..don’t loosen it up…..
