    Subject: Re: Are Vne and Va IAS or TAS?
    Pete, Quick answer: During prop testing, I would do cruise tests up to 15k, then dive at Vne in smooth air to the turbulent layer at 5000, then slow to below 130 of cours e. No issues. (Did a loop at 160 just for practice.) Later to determine prop pitch to hold 5000 and 5500 rpm, I shallow dived to Vne and observed the rpm, landed, adjusted the prop course stop, and repeated. The pitch and roll forces are a bit lighter at Vne, but still delightful. Now you know why I'm a zealot about stab tightness, and flutter. I do this type of testing on my new 914 / Airmaster powered planes I flight test. By the way, in my last post, I didn't include wing flap vs local AOA change resonance at high altitude in flexible wings of low elastic modulus. Nast y stuff, and very lengthy to explain. Keep it tight. Regards, Bud Bud Yerly Custom Flight Creations From: Pete Sent: Wednesday, January 10, 7:01 PM Subject: Re: Europa-List: Are Vne and Va IAS or TAS? Hi Bud, Many thanks for your (as always) comprehensive post. Very much appreciated. Your bolded statement implies that the Europa would be fine to be flown t o VNE IAS at 15-18k (altitudes used by some Europa fliers) without risk of flutter due to the relatively stiff construction (if I have not mis-read). I'm quite hesitant to ever give that a try, but was searching for the comf ortable TAS limits instead... which Ivan has appeared to answer with his pr oven test numbers. Now im wondering if any Europa fliers have become test pilots and flown at VNE IAS higher than Ivan's 8000' during his Vd testing? Just recently, another composite light sport didnt fare as well: https://www.flyingmag.com/technique/proficiency/technicalities-are-you-feel ing-lucky<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F %2Fwww.flyingmag.com%2Ftechnique%2Fproficiency%2Ftechnicalities-are-you-fee ling-lucky&data=02%7C01%7C%7C4806ff4b8a944b1ca90208d558867988%7C84df9e7fe 9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636512256952691615&sdata=r6v3ZE7X3X9wsg TXWlnMABwg1fzm4Ym%2FIbzzdeuWjL8%3D&reserved=0> Cheers and blue skies, Pete :) On Jan 10, 2018, at 4:15 PM, Bud Yerly <budyerly<mailto:budyerly@msn.com>@m sn.com<mailto:budyerly@msn.com>> wrote: p

    Subject: Water cooler vs duct
    I have a set of Nevs cowlings, with revised radiator duct sides ( CD2&3), Nev acquired for me a radiator with extra jackets to the side and side exiting hoses. I have installed it which involved cutouts in the side panels, this means mounting forward of the footwell. I now have not enough room between lower cowl and the radiator, Ie negative by 10mm. Has anyone fitted this sort of radiator? I am close to ditching it and fitting the original standard, (does anyone have a spare? Alan Twigg Motorglider kit 463 Almost there, radiator and control set ups to go. 2018 might be the year. Sent from my iPhone

    Hi Alan, I too have installed Nev's cowlings and I took his advice to fit the same water radiator in the same position as found in the XS installation, but I also took his advice to use the oil cooler from my original Classic cowlings. No problems. Perhaps you could attach a few photographs to enable better understanding of your set-up.
