I am will soon be building a paramotor with endurance capabilities in mind. I am open to suggestions, comments, questions. This would also be a great place to hear from everyone on their longer endurance builds and paramotors.
As for the basics this is what I am planning on:
- MAD M40 43kv motor
- e-prop 125cm 4 blade or 2 blade. I will test both
- not sure on esc (square wave or sine wave esc?)
- for the battery I will likely use a 22s15p Samsung 30Q pack
I would expect roughly one hour flight time on an XL wing. The Paracell paramotor claims to get up to 70 minutes with 6 more 30Q cells than what I will likely use. (their battery pack will hold an extra 60wh of power under load). This number is also par with the flight time to battery kw ratios of Exomo, Skyjam, Black hawk AMP, And sp140. Because most of the time wont be flying an XL wing and I wont push the battery to being completely dead on every flight I do expect to get closer to 45 minutes on the average flight.
I would later like to try and use a 22s20p battery to get theoretical flight times over 80 minutes with a large wing.
One thing is I want it to be able to do with this paramotor is hold 130+ lb constant thrust at 5000’ for climbing up mountain sides with medium or small sized wings when flying with gasoline powered buddies. I know it will kill the flight time, but I would like to have that much power when I want it.
