Yes, this is because there are no significant 'white noise' drag spots contributing to the overall sound. Just the wingtips where the airflow has been carefully led to those small vortex concentrating tips where it is compressed and whirls away making that (I think) nice whistle sound.
This is a noise you want to be hearing on a fast model.
High pressure vortex shedding = Much less drag. Much less chance of tip stalling.
If you dont hear the high-pitched whistle on a fast fying model its because the air at the tips is not 'organized' and is shedding in a ragged manner. If you hear "white noise" its because the model is generally a bit draggy but trying to fly fast.
This lift distribution and flow management is something I have been working on for some years - hence my (originally thought to be) weird wing shapes. Now more and more F3f designers are following my ideas, but I wonder if they could tell you what is actually happening and why?
So far the utimate expressions of this design philosophy from me are the Spada GoFast F3f and the Toccata; with the Toccata having a very advanced and unique wing design indeed. I think anyone who has seen a Toccata fly, or better yet tried one will know what I'm talking about.
I do go on, dont I? LOL
Cheers,

Phil Davy is at it again - this time its a showdown: Baudis Jedi F3b Vs Aeroic Spada S
Disclosure from Phil :
I do not receive any money or compensation from Aeroic or any other company!
So, it was very hot & humid out there. I had just cleared the entire LZ by myself and I ran over to throw a model up because it was on! So, I was a little louder breathing because of it. I also situated my phone mic too close to myself. Apologies for that.
The JEDI had the advantage due to a fully finished model program in the TX. It came from my Pitbull years they act nearly identical. The SPADA will receive changes in settings before the next session. The SPADA was much lighter at 105 oz and with its smaller wing area it would have loved the extra weight.
The SPADA has an incredible mix of upgraded sub systems in side and sexy slim lines.
Overall design and out of the box thinking the SPADA is a better model. It’s more nimble and changes direction really well in sucky conditions.
The finish on the SPADA is beautiful with a A for finish of the layup. My model was a pre production copy with a few nagging fitment details that Aeroic says will be ironed out for production models.
I think these if priced smartly will be a “natural selection” towards these concepts aboard the SPADA.
BTW
Both models are built the same with the parts below.
Wings
KST X10 Thomas Liu LDS
Fuse
KST X12
Battery
Spencer pack 3500mah 2s Li-ion
Full plug n play wings
I was so impressed that the SPADA kept up this pace at 105oz. I can’t wait to ballast it up with tungsten!
Looks like Phil is enjoying himself - which is what its all about!

Spada 118" MKII, Gents.
Some internal and small external changes.
Old wings can fit new fuselages, but new wings won't fit the old fuselages.
It's strong and it's quick.

All-new E-Spada 118"
Want to get high, fast? Feel the need for speed?
OK - Stuff in a hot motor and a capable battery, and you are in business.
