I have been looking into building my own electric paramotor so I have researched every electric paramotor that I can find. That one is the Minne paramotor. These are my problems with it. the paramotor is running a small enough propeller that it takes away almost every efficiency benefit that you get from a single propeller(40 inch prop), it uses lawn mower batteries which are heavy and don’t hold much power, the unit weighs far more that your Open PPG units, the Open PPG has more thrust, his paramotor uses some of the cheapest components you can find, And he is charging you way to much for the unit.
I could show you how to build that exact thing he is selling for about $2500 and save you a lot of money.
In my opinion the Open PPG is a far better option as it weighs less, has more power, better flight time for the same weight, uses better components, it costs less, and offers no torque twist.
*Update: I looked back into it again as I haven’t in a few months. Here is a comparison to the Open PPG 4x
WEIGHT (w/ out batteries):
Open PPG-21lb
Minne-32lb
MOTORS:
The Open PPG uses some fairly high end Mad M10 IPE motors which would cost any of us $267 a piece or $1068 for all four of them. The single large Minne motor can be bought out of china for $285. To me this is a clear statement about the quality difference between the two.
THRUST:
Minne roughly 75lb thrust
Open PPG 150-160lb thrust w/ 7s lipo
BATTERIES:
---------------------------Minne---------------Open PPG
Number/type ------3x lawn mower ------4x Bonka 7s
total cost------------- $700usd--------------$1000
total weight ---------16.5lb -----------------22lb
voltage ---------------80v --------------------51.8v
AH --------------------12ah -------------------44ah
Total PWR ----------960wh -----------------2,279wh
w/kg ------------------130w/kg ---------------231w/kg
*these are all rough numbers
As the batteries go, the Minne are heavy, low power, and cost a lot for the power they provide.
FLIGHT TIME/ TAKEOFF WEIGHT:
Minne- less than 15minutes - 49lb takeoff weight
Open PPG- roughly 25minutes - 43lb takeoff weight
these are all just rough numbers. I probably got a little to carried away. Based on all this I think I would stick with an Open PPG as it costs less and it is better in almost every way.
