I do not own a SP140…but hope to. To me the angle does seem a bit much. Assuming the horizon is flat there is a relative 27 degree angle. Now note that everyone’s angle is “unique”, and while under power the angle may be exaggerated, but a decent resource (https://paramotor.guide/paramotor-hang-test/) shows about an 8 degree angle during a hang test with no power. The PPG Bible states the range should be 5-15 angle. I would recommend performing a hang test (e.g. in your garage), taking pictures and trying to aim for an angle closer to 8…but again will require some trial and error. Just my 2 cents and look forward to hearing from experienced/knowledgeable fliers…because I would also like to know.
that angle could be dangerous under full throttle
I would recommend the following:
A) Tighten up the top straps of the harness as much as possible. Pull the seat back adjustment as far forward as possible (not as comfortable but still good).
B) Move the goose neck rings as far back as possible without going down the bar
C) shorter motor spacers
D) longer shackles (lowers the seat about an inch for moving CG forward a bit)
I also front mounted my reserve for more weight up front.
these are the shackles: I got: Self-locking tack shackle - Dia 6 mm | Wichard Marine
these are expensive! not as wide as the originals but they work. they are super secure and feel like they don’t even need a security wire (still put one on)
hard to see all the changes, but this photo you can see the shackle:
155 pounds here. In order to change my angle from the first pic to the second, I had to move my hang points back a whole lot. It’s a bit awkward to attach in the risers, and braking is more outwards rather than straight down, but it works.
I have small arms and it’s already tight with the new bent arms from openppg. You should try them to see if it will work. it will improve your hang point position but it’s so much tighter at the arms, I’ve already banged my elbows a few times flaring.
spacers and a front mount reserve helped with my GC.
I just picked up my SP140 the week before Christmas and have been going through the assembly and tear down process, as well as setting up my hang point.
So, what is the latest solution to the hang point adjustment? Here is what my hang check looked like with the hang points set up as the unit was delivered.
Then after I adjusted it for proper hang angle, about 5-15 degrees, the ring is about here, 2 inches down from the bend radius of the swingarm. I read some concern about the rings slipping from that location. Is that the only danger trying to fly it this way? If so could I just add an extra collar or two to prevent slipping?
What do you guys recommend? @Pdwhite said he had plans to make some shorter bars with a different bend point for us lighter pilots? Are those ready or should I try some other fixes in the meanwhile?
