The exact year (or at least the decade close to it) is a VERY important "detail" to make history...
Back in 1999 (as far as I know) there where only 3 pages in the internet, referring to RC Model Hovercraft, one was mine.
Some years after, the first international (no internal/national ones at the time!) appeared and still exists:
If I remember, we where in 2004 or close...
NO ONE AT ANY TIME (since now) referred/posted or remebered such a thing as you are telling us now...
My guess is that you are confusing the Byron ducted fan that I am using since 2011 (tested and posted here, in this forum back in 2010) with some other...thing!!
I trully hope that you can find (or someone else) some reliable proof
of that milestone!
I am a bit unconfortable, being the first in such manny achievements in R/C model hovercraft
as; introducing 1/4 scaled Racing
Hovercraft, using a BYRON ducted fan
in rc model hovercraft, making the first scaled rc RACING hovercraft, the first (since some decades ago, not copyed till now) to implement a full realistic moving figure
(pilot),probably the most performing RC hovercraft, and so on...
Yes, I know, I am NOT (anymore) a modest person, I gave up being it some years ago!
After working hard more than 20 years on developing a big amount of Hovercraft models and improvements, most of them prooved and milestones shared in the internet
(some of them that can be used and implemented in real scale Hovercraft)…
