Homemade cheap ppg

Hey guys, there is a video of my homemade paramotor, CAD-files and Arduino code under https://grabcad.com/library/ppg-2
The Video how it works is https://www.youtube.com/watch?v=lo38WtriIUM&t=6s

What do you think?



Awesome! Nova Wing, beautiful mountains … looks a lot like Austria … where are you located?


Looks good, reasonably light, and of sufficient power. But how many batteries, how much additional weight, and how long will it keep you flying?

How much thrust does it generate?

Hey, it is an old triton :wink:
South Tyrol - Italy

it has about 32Kg thrust, and 48V x 22000mAh… it is not that much, so i will add two adittional smaller props and another battery pack :slight_smile:

In your view what is the advantage of two smaller motors compared to one?

Hi Bob, i would say the absence of torque :wink:

Very true. I have just been concerned about what would happen if a motor failed on a full throttle climb. I would think that you would get all twisted up and left with no option other than a reserve, but I could be totally wrong.

There are a few examples here in the forum of motor failure in flight and most never even noticed the failure. Twisting is not likely an issue.

the path of a successful developer is always to put practice far above theoretical knowledge. that means you hang yourself with your EPPG on a swing with the same carabiner spacing as when flying with the wing. then you give full throttle. you can then see what effects this has on twist. if you want to compare the torque of propellers of different weights (with single prop systems) you attach a measuring scale to each suspension. you can also compare the thrust vector under load very well. so you don’t take any risks with your first test flights. the actual perfect adjustment then takes place in several flights. just like acro pilote then mark their setup on the straps to find the perfect setting again and again. and by the way: a properly built eppg / ppg has absolutely no problem with torque with the single prop. no matter if eppg / ppg for pure moto flight or eppg for thermal flight. you can see it very well when you watch videos on youtube. you can see very clearly who flies a good setup. in terms of geometry, power and performance. especially very clearly at the start.

In https://www.youtube.com/watch?v=JMLRy8dfzRs&ab_channel=SCOUTparamotor he talks about how his test ring isn’t a paramotor, or even safe, because it doesn’t have the fins a scout uses for torque correction. In the comments, he makes it clear that there are other fine ways to correct for it, but that the correction really is important.
