Default Testing Electric Propulsion Unit For a Light Airplane

Hello everyone, new here.
I want to share the results of our testing of a prototype electric propulsion unit for light aviation with a power of 80-100 hp.
Our tests showed that the 190 kg thrust that we get from our electric setup is enough for the aircraft takeoff and ascent.
🔥🔥✈️✈️✈️🔥🔥
Since we're new to electric aircraft in general, I'm curious to hear some thoughts about our tests from people with more experience.

P.S. English captions available

I think it may be out of the league of most modelers (unless of course it is just a clever way of advertising?)

This is a Electric Radio Controlled Model website. Most of the motors we use will easily fit in your coffee cup. I hope your research continues and you are successful in developing a full scale electric power unit.

Ooopss.. Sorry guys, I really should've done more research before posting. It's just we're looking for someone with more experience than us in electric propulsion and electric planes. We already have some experience of converting cars to electric power, but converting planes is something new for us, so, interesting challenges ahead! Hopefully, we'll find some people who are kind enough to share their expertise.

There were several 1:1 e-flight e-mail discussion groups on groups.yahoo.com, before Yahoo pulled the plug on e-mail groups in 2020. I was moderator/'owner' of two RC dedicated groups there.
They may have moved to groups.io, they had plenty of time, you could do a search there.

You could also ask around for pointers in these RC (sub)fora:
www.rcgroups.com/giant-electric-planes-477
www.rcgroups.com/power-systems-13
www.flyinggiants.com/electric-power-4

A good mix of 1:1 and RC in this video
That section starts @12m40s, determining optimal coaxial setup distance. Not quite Scrapheap Challenge

I'm probably preaching to the choir here, but motors don't produce thrust, propellors generate thrust.
Prop recipe for lots of thrust but no speed: large diameter, low pitch

Yep, you're right. Not a native speaker, not to mention all the plane stuff specifics, translation is hard, so sorry for possible bloopers.
By the way, I tried to register in RC groups you mentioned, but had no luck. After seemingly successful registration the website decided that I'm a spammer and blocked me out. Not sure what triggered that.
Anyway, I filled in the contact form, maybe admins will let me in.

We also looked at you as a spammer until we figured out what you were looking for. Hopefully they will arrive at the same conclusion.

I assumed you are an electrical engineer. Like me
