Thank you for explaining the aerodynamics of the slats. That's some seriously good engineering
It a pleasure to do this👍
People always told me that German modelers were the best of the best. They were right! I LOVE this airplane, and the level of excellence and craftsmanship you put into this is second to none. I'm sure you'll figure out the gain and PID settings soon enough... just watch out for nasty shear! Send up a little foamy first as the scout. The quad will compensate so fast it will mask the problem. Maybe geofence it for ~9m altitude?
Sounds great, I will do so 👍👍
It's stupid simple. Germans have the coolest toys in R/C bare none.
16:22 incredible, both on the piloting and the design!
Yes that was a wonderful day 💯
Hello! I really enjoy your explanation of aerodynamics. It has been very helpful to me
You're welcome mate 🙌

Thx mate 👌
Beautiful Jet
Thx mate 🤙
Wow... nice work i want one 🤣🤣👍
Great video!
Thx mate 🙌
I am doing my thesis about light weight wing slat for Boeing 737 using composite materials! This video help me lot! Can you explain the calculations please?
well bugger here I thought I was the only one who came up with this idea ... I guess the idea's time came and many got it and are figuring out different ways to apply it
I wonder if each of the flow indicators (threads) could transmit data to the flight computer in a plane to warn about stalling conditions in real time.
Super idea😊👍👍
I think instead of threads you could use some sort of small tube like a Pitot tube that would transmit different pressure readings back to a micro controller that could compare readings and extrapolate when a stall condition was approaching not sure if the system could be made small and sensitive enough for use in an RC that size but it would be a neat concept
@@rickscott0204 Thanks Rick and great idea! I´ll keep it in mind :)
14:00 But that motors already throw turbulent flow on the wings. Like you see not so laminar at the surface.
but the slat work. the firs row of shreds are all time still. good work
Surely this would work better with non swept wings as more of the airflow stays as chord wise flow and less is converted into spanwise - hence if there were no sweep angle it would be easier to fly slower? Also are there any negative effects to the performance with these on during higher aoa manuevers as they would likely produce more drag?
High alpha (AOA) maneuvers are typically used in close combat situations, and can benefit from increased drag in a couple of ways:
1: The aircraft slows down more before completely changing direction, spreading the delta-v over a larger portion of the maneuver, decreasing the peak g load on the pilot.
2. This also allows the aircraft to be capable of an even tighter turning radius, which in addition to thrust vectoring nozzles, increases this ability even further.
Often in combat, the more maneuverable plane is the winner. Advanced electronics can only compensate so much.
The main reason you don't see forward swept wings much, if at all anymore, is that a trapezoidal wing (if properly designed) can have as good of alpha drag as a forward swept planform, without the potentially fatal flaws and quirks they can (though not if designed correctly) exhibit.
You have to admit, the SU-47 looks sick, though!
Layman question, doesn't this increase drag?
How to take dimensions of slat with respect to wing?
a little english hep carbon rod ... you are saying carboon ... it is a short O like in turn ON the light ... car bon ... bon appetite
Да всё не так, ты просто увеличиваешь эффективную площадь крыла, вот и всё, никак не влияет эта щель на что либо, можешь полностью выдвинуть предкрылок и залепить эту щель изолентой скорость сваливания будет абсолютно такая же как со щелью, учитывая что самолёт летит на разности давлений под крылом и над крылом и не на чём больше, эта щель скорее паразитно травит давление уменьшая подъемную силу. Расчёт подъёмной силы, современный сводиться к тому, что самолёт как бы натягивает поле давления как за собой так и перед собой, посмотри каких нибудь американцев, у них там мощные компьютеры и они посчитали всё это векторное поле уже всё без ниток.
In reality it works quite well.
