Hey great video! Literally everything you said is correct however, the simplist solution for the 90% of trikes made with a completely horizontal thrust line is to just swap out the front tire to something smaller and/or use larger diameter ones on the rear. After that, do what you should already be doing regardless and conduct a hang test for in flight pitch. Keep up the good work! Maybe one day we won't have to watch as many people at the field ball up their wing when they roll on power, lol.
Yes we could. I did not include it here as I try to keep these videos educational and as little commercial as possible. Yes, of course its hard not to be biased.
The thrust angle in the air is TOTALLY independent of the thrust line on the ground and NOT affected in the way described here. You set your hang points to give the in the flight thrust angle required. You set the geometry of the trike to set the thrust angle while on the on the ground. The 2 are not connected.
You had a photo of a Power2fly Colibri trike with 90 degree thrust line. Since the colibri have adjustable thrust line I would say it is by no fault of the manufacturer but of the pilot. Greate info and good work with these geometry series videos!
On my converted from delta paratrike I came to this conclusion after, well, quite a lot of try and err and a lot of thinking (though I didn't fly it near that often compared to my foot launch). Thanks! Waiting for more!

Great video and I've watched and took everything onboard ...the thing is Ive been flying trikes for some ten years paramotors for twenty , and all of the trikes I've flown are straight upright or even reclined back around 5 degrees. Yet I have never had any issue with bad inflation of any of my wings or any issue with my takeoffs ( many videos available ) so I am wondering is everything I've done totally wrong and i am a one take off from death ? could you explain why I am not having any issue ...also what I don't also understand clearly is lets say i was flying along and my prop is perfectly up/down then i hit full power i will accelerate and the wing will drag back causing me for a moment to in effect lean back putting me into a dangerous angle I don't disbelieve anything you say ....but perhaps I hold reservations
Replying to myself and just to let others know ! I’m still flying my trike and its still leaning back a little bit ( on the ground and in the air ) still having no issue with my take offs and have therefore come to the conclusion it makes no difference AT ALL if when on the ground the motor is leaning forward , straight up, or leaning back …..so in this aspect your wrong ! I’m afraid I have carried out extensive real world tests …and not in the classroom or on the blackboard
Still no Scout trike to be seen anywhere on the Scout Aviation Channel ...... WHY ????!!!!! Most potential Scout customers cannot run with a two stroker in their backs. Wheels are needed. Light and minimal. Love Scout.
I really enjoy your class-room keep up the good work, i can't wait to see the next video. About the reclined angle, if mounted abit longer main bar, you'll be able to fit an extra fuel tank and be as reclined as you want ( look at the flyproduct Vertigo example) . make that trike with medium goosebar hangpoints, the correct angle of the propeller, and trourke compensation, and take my money ;) . Let's get into the next classroom soon plz :) Would be pleased to hear your thing about active/ dynamic flying on trikes, we´re a few people out here who cant foot launch, especially with the Scout setup
Mine is a home built and it used to be an about 75 degrees. I had a lot of trouble with propwash on takeoff I changed it to 90 degrees and it is much better now I can't speak to the efficiency of my flight but it seems fine to me
Great videos keep up the good work. One question I have is It doesn't have anything to do with a thrust line it has to do with a propeller. Do you think putting a propeller and a duct would help with thrust and noise Possibly getting more thrust and less noise for the same amount of power putting into it or possibly less energy going into it. Looking forward to hearing from you thanks Mike from the USA
As long as it is safe, choose what is more comfortable. To me, a harness is always more confortable than a seat. Even passengers feel more secure as the harness hugs the body more tightly.
Correct me if im wrong but if you are leaning forward by 20 degrees on the ground you will still be in the same uncomfortable position as what you are in the air because the tike and engine dosent move as its all fixed you pivot on the arms or hang point so you still will be uncomfortable in the air now if you had and adjustable engine to change the angle between fly and take i could understand but it dont 🤔🤔🤔
Just take a picture of a trike landing just before touch down. Then you will see, that the front wheel is a bucket size higher than the rear wheels. You can simulate that with a simple hang check :)
wrong in the air? you move your hang points to adjust the angle of your dangle. and the upward air thrust would still hit the wing as it comes up. it just hits it later.
Well, speaking of things trikes do wrong... what's the aversion to caster front wheels? This way the trike would tend to follow the direction of the wing 'automatically' wouldn't it? Some do this, and it makes sense to my feeble brain. Yeah sure there's a pilot on board that should be doing that anyway but still... ?!?
This may be hyperbole, but all these trike manufacturers reply to this video by saying "We've built these for years and never had a problem", then the cycle of crap continues.
@@miroslavsvec you're good bro! Don't worry about the haters. LOL. I will be starting up my own paramotor company very soon. I don't work with carbon fiber though. I am an aluminum man by trade!

I admire your knowledge and your talent when it comes to engineering paramotors and your passion for aviation! I would very much like to sit down and BS with you about paramotor designs and all the technical stuff as well, if you would ever be interested in doing that of course. I think we are already friends on Facebook, which is where I use my real name and not this anonymous title of "Some Guy." LOL.

@@someguy7258 no I don't think the was any hatred in the comment. I am grateful for notifying me. Good luck with your new paramotor design. Your already have the prototype?

I thought I had that great Idea to change the Thrust line with bigger rear wheels, but you had it before me. Good on you mate :)
The only other trike I've seen do this is the Fly Products Vertigo. Definitely makes a tangible difference. Glad this is being addressed
I just bought a Trike Buggy. Thank you for this excellent demonstration. I will make changes.
TOTALY AGREE WITH YOU ON THE DEGREE OF ANGLE THRUST WITH A TRIKE HAVING BUILT MY OWN PPC USING THE PRINCIBLE IN THRUST LINE. MINE WORKS FINE...
@@helicopter2992 who said his isn't safe??
Very interesting! Will you have footage of the Scout trike doing an inflation at some point?
Yes we could. I did not include it here as I try to keep these videos educational and as little commercial as possible. Yes, of course its hard not to be biased.
@@miroslavsvec it's your channel so why wouldn't it be a scout lol. I just wanted to see your trust angle in action so I can thrust what your saying

Great info! I always wondered why the Thrust line of a trike is different than a foot-launch.
why not show a video of it with correct trust angle?
Love the airflow tattoo.... and the videos
What I've learned here, is that you should really trust Miro...and all of his angles.

Great advise. Makes total sense. Will adjust angle.
How?!!! there is not an "angle adjuster" on most trikes....

Been waiting 3 years for Part 37
The airparamo grazzhopper uses the forward thrustline as well
My adventure funflyer v1has also the right setup . Takes off and flys very wel , old but still good
Mine is a home built and it used to be an about 75 degrees. I had a lot of trouble with propwash on takeoff I changed it to 90 degrees and it is much better now I can't speak to the efficiency of my flight but it seems fine to me
Hmmm, good to know. Thanks.

Seems to only find this one call about trikes, did the class end before all lessons were publised?
any videos to see the difference? thank you.
WHERE is part 2?
So should I do my hang test and then set my prop angle at 90 degrees. I made my trike so you can adjust it from 6deg to 13 deg
Gracias
I didn't see the question asked, so I will. Is possible or practical to modify engine mounts somehow to gain the 10 degree or more incline?
Could you talk about the seat of the trike? Better a normal ppg harnes picked on the trike? Or better to mount a independent seat with seat belt?
As long as it is safe, choose what is more comfortable. To me, a harness is always more confortable than a seat. Even passengers feel more secure as the harness hugs the body more tightly.
Waiting
How about adding some more trike videos trike becoming more popular Compensating talk on a track Thanks
Thanks bro...
Correct me if im wrong but if you are leaning forward by 20 degrees on the ground you will still be in the same uncomfortable position as what you are in the air because the tike and engine dosent move as its all fixed you pivot on the arms or hang point so you still will be uncomfortable in the air now if you had and adjustable engine to change the angle between fly and take i could understand but it dont 🤔🤔🤔
The whole trike will lift the front wheel after take off and lean backwards
It depends on your wing hang points once suspended by the wing. More weight behind hang points your nose will raise and vice versa.
Just take a picture of a trike landing just before touch down. Then you will see, that the front wheel is a bucket size higher than the rear wheels. You can simulate that with a simple hang check :)
wrong in the air? you move your hang points to adjust the angle of your dangle. and the upward air thrust would still hit the wing as it comes up. it just hits it later.
Meu sonho é ter uma dessa mais moro no Brazil e é caro se tiver uma ai de test manda pra cá uma estrutura #TAMOJUNTO
Great videos, but 90%+ are not parallel to the ground. They are angled forward.
Bad inclination of the trike in flight comes from wrong balancing. It can be balanced to be level in flight, so the prop will not face up
All this change for an un-noticeable difference.
Well, speaking of things trikes do wrong... what's the aversion to caster front wheels? This way the trike would tend to follow the direction of the wing 'automatically' wouldn't it? Some do this, and it makes sense to my feeble brain. Yeah sure there's a pilot on board that should be doing that anyway but still... ?!?
So what happens if you lose your motor?wont you hit nose first with out having trust from your motor
Think first, then ask :)
This may be hyperbole, but all these trike manufacturers reply to this video by saying "We've built these for years and never had a problem", then the cycle of crap continues.
90 degrees, everything is fine: th-cam.com/video/SfcBNHMUoaY/w-d-xo.html
This is nothing new, it's a basic rule of thumb in paramotor trike construction. I haven't seen a trike in a long time that doesn't have it!
