Hi Jan, Good write-up! However, don’t see this covered. It seems in the case of high wing CH750 fuel is delivered to the header tank via gravity. How would fuel be delivered to the header tank in a low wing CH650?

<p>Hi Michael</p>
<p>I have ordered and expect my AM15 to be on its way to NZ soon, have you decided on your engine yet? I am building a 601HD so a low wing and have debated the header tanks etc, in the end I took Marks advice and just went for the wing tanks with the duel fuel selector at the end of the day I could if I wanted to install a header tank at a later date but I would have to then have an extra two fuel pumps etc etc, that all adds extra weight and as previous people have told you I…</p>

<p>This is what Mark from Aeromomentum said to me. There's advantages to both, but overall a header tank definitely adds complexity.</p>

I am not a fan of header tanks due to the added weight, complexity, cost and additional failure modes. Duplex valves are just $200 and allow fuel return to the specific tank being used."</span></p> I'm down to Viking and Aeromo…tag:zenith.aero,2018-08-17:2606393:Comment:6419852018-08-17T13:51:48.763ZMichael Doornboshttps://zenith.aero/profile/MichaelDoornbos
<p>I'm down to Viking and Aeromomentum. I really like the UL, but it's just so expensive.</p>

<p>Both engines give me a little pause. I probably don't have to decide for a couple of months. I'm only just getting going on the wings so...</p>

<p>Yeah, I got it on the gear, have another Quality control issue with a part. This time it's the lower nose gear bushing.</p>

<p>Cool. I haven't been to one before but I am planning on attending this year. There is a very good chance there will be an Aeromomentum engine there this year. </p>
<p></p>
<p>1) What are you down to now in narrowing your list? </p>
<p></p>
<p>2) Did you get the airframe on the gear? Get it moved out to the hangar yet? Sorry I missed you while I was up in Sylva NC. It was a lot of driving there and back especially traveling with kids etc. </p>

<p>By the way, what I “heard” I got confirmed by Aeromomentum. They don’t recommend header tank design, but the engine will happily work with one if that’s what you have (obviously). </p>
