Beautiful work my friend! This is why I love experimental aviation and tweaking a new idea until it works is part of the fun! It'll either work or you'll be a lot closer to something that does! Keep up the great work, I love it!
There is some thinking going on outside of the…..cowl here, great work, keep it going. Since you asked, my only concern is the in-line fan you intend to try. I would be a lot happier if it was NOT in the primary line, but in its own branch line. It’s going to act as a massive restrictor if it fails or gets contaminated in some way.
I hear ya, I have similar reservations however in ground testing so far the fan didn’t restrict airflow even when off to a point where I could see a difference on temps
Great work as usual! Can’t wait to see some engine trials and whatnot. The Yamaha/snowmobile engines are really interesting to trouble shoot vs air cooled
Not saying this casually, can see how much work this is and love your cowl. I think the fan works much better on the back side of the rad pulling air. and coming on automatically with temp.
The fan wont know the difference in this case but yes, In a normal automotive installation without a sealed plenum like this, the fan is generally on the back side rather than the front. This fan is designed with a reversible rotor so it can be run on either side and it will be controlled by water temp👍
The video appears to show the Flightchops duct outlet being both tapered the wrong way and with no lip rolled into it. No surprise that the duct won’t stay on!
I’ve found the DAP maxfill to work best for me.. it’s the closest in “density” to the pink foam so sanding isn’t to tricky. I’m sure I didn’t try all the options, but the standard “great stuff” was not one I would recommend.
I hate to burst your bubble, but where wings are concerned, Bernoulli effect is more of a side effect than a primary cause of lift generation. According to NASA, a wing is primarily a flow turning device. The Coanda effect has more to do with why a wing is shaped the way it is. Bernoulli effect can only account for a small amount of the lift generated by a wing. That's not to say that pressure differentials aren't relevant in other aspects of aerodynamics / ducting.
I don’t disagree be any means. Only intended the reference to serve as an example of how the effect works in a practical visual way. Thanks for your comments👍
I feel that the front air intake needs two teeth off of the top lip. Aerodynamically not advisable but as far as character and personality of thew aircraft ... its a winner :-B
I have no idea if what you are doing will work, but the craftsmanship is top notch and your ideas are top notch.
You and me both! Thanks for the kind words👍
I have binge watched this series all day. Awesome build.
Thanks for following along sir!

Thanks brother
Taking a page out of Patey's book and doing a bit of an experiment isn't exactly a bad thing. Happy to see some updates!
Couldn’t agree more, thanks!

It keeps looking better and better. I still can’t believe how smart you sound on video.
If people only knew 😂
Lol.. don’t tell my secrets
Beautiful work. I'm sure you will be rewarded with a great flying aircraft.
Thanks!
Looking good!
Thanks guys!

Thanks! That’s coming up soon!
Good work and nice video!
Thanks!
Can't wait to see the results. Keep up the great work. Love the videos.
Thanks
Great effort. Well done and yes at the very least the cowling will look great.
Thanks!
Such a good video, keep up the good work!
Great to hear from you! Thanks for watching👍

Not mine! But “If it works? Is it really a dumb idea”? Love what you are doing.
Thanks!

I agree, much improvement could be made on that baffle flange
Just hope you keep the hog graphic on there!
We shall see..
Note- the Wright Brothers original (1903) engine was water cooled.
Congrats, should work
Thanks!
What about rain going in from the top, especially parked on the ramp.
Not gonna hurt a thing, it’ll drain right out the bottom..
It's a good thing you don't live in Ireland like me ☺ ☔
Take a look at the hood vents on the Ford GT 40
I’ll do that, thanks!
What spray foam are you using exactly?
Thanks.

Are you using an apex based Yamaha? HP estimate? Great job!
No sir, this one is the sidewinder 998t 3 cylinder
I feel that the front air intake needs two teeth off of the top lip. Aerodynamically not advisable but as far as character and personality of thew aircraft ... its a winner :-B
I'm gonna need a little somethin'-somethin' if you plan to use my likeness on your cowl... Kidding aside, great work ideas!
Always great to hear from you!
Stop blaming Bernuli.
