From: "Monoman" Further to the leaking fuel tank thread, I am also just about to replace all fuel and oil hoses. Can anyone tell me roughly what length of the various hoses to order? I have a classic with 80HP Rotax.

In tuft testing, placing tape and tufts at the 50% chord point significantly changed the deep stall and cruise trim characteristics. Another really annoying thing is for those who built their ailerons true to design and have a slight concave surface on the aileron upper side, any water or frost still on the aft trailing edge is noticed in trim. I use a #10 wood pencil or soda straw for initial trimming simply taped as a ramp to the aileron. It is amazing what a small amount of change as a 4 inch tab can affect roll trim. I had 12AY down for a month after a local Instructor pilot flew my plane on a short cross country and reported back that it too an annoying amount of rudder to keep it straight. I checked everything. It appears the plane was left outside in a strong thunderstorm and the rudder was banging around which caused a slack rudder cable turnbuckle to flip the cable thimble around which shortened one cable about 1/2 inch.

It's also annoying that when the cold-soaked aircraft is dragged out from the cold hangar, water then condenses and freezes on the wing surface a very fine hoar. That's happened before, but makes no difference to trim; so the boundary layer thickness is between that and the size of half a pea.

A second radiator, oil or coolant, should not be required in a Laminova set-up. Removal of the oil radiator in the duct of the XS will increase the flow of undisturbed air through the coolant radiator and more than compensate for the heat load added to the coolant from the Laminova. I have a classic and for several years had to step climb to control temps. I no longer have to do this. I keep the airplane at KPGD (Punta Gorda, Florida) and at KEYW (Key West, FL) and in a typical year stay in south Florida until July before flying north. To be clear: I have flown many times with ramp temps in excess of 90F (33C) with no ground temperature issues and at 4500ft, 80F (26C) with no necessity to step climb to control temperatures.

I wonder if the classic rads could handle the 100hp of a ULS with your setup.

Consistent with the constraints of my ability to accurately measure the size of the 'O' ring I purchased, it appears mine is the same as the one in Michel's drawing so I feel more confident now that I have the correct size. Thanks again mate.
