RE: C-ARF Ultra Flash build Thread + Video

I get you, I have the k140g in mine, radared at 265mph a few months ago with the bypass.

That turbine is one heck of a power plant!

RE: C-ARF Ultra Flash build Thread + Video

Why would you not use the...

Congratulations and yes, the felt clunks can be an issue although not for everyone and the main fuel tank is empty when it still shows about 1/2 inches of fuel at the front (because it leans slightly...

RE: C-ARF Ultra Flash build Thread + Video

Since I had to switch to metal clunks and do away with the felt its really difficult to fully empty the tanks then once I disconnect the main tank from the wing tank I end up covered in diesel.

RE: C-ARF Ultra Flash build Thread + Video

Im thinking of adding saddle tanks along with the main and wing tank in order to get a longer flight, has anyone run 4 fuel tanks? what was your experience?

thanks

Hi Pat

The funny thing is that when I isolate the tanks they both still feel restricted which is why I suspect the clunks are blocked, also this system worked fine for many flights before now.

Thanks Pat

Luckily I have bvm heavy clunks at home so I will change them later, I will know if it has worked because there will be a lot less pressure when I blow into the tanks.

I will leave...

I'm going to meet Barry at the field tomorrow, he's bringing his laptop and wire so more data to follow, I think I'm going to change the clunks anyway

Hey,

yeah I had that issue to but now work around it my new issue is that the UAT collapses under vacuum as the pump draws fuel and i cant find an obvious blockage in the fuel system

RE: C-ARF Ultra Flash build Thread + Video

thats either because you don't have enough down mixed in or your not flying slowly enough.

with full flaps you should be in the 25 to 40 mph range without balooning

I don't see that removing the inlet joiner will help acceleration, the intakes on the UF are big enough to feed that turbine, especially in the mid to low range, i think its mostly down to the...

Exactly,

I think the biggest problem people are having is caused by way to much flare/poor setup, with the full 4" flaps you almost don't have to flare it, really my UF lands best when its as...
