Andrew,
Might be better at 1pm, giving you a better chance of staying up!
You'll also find weight shift thermalling limited, compared to a free flight harness.
Glide is also quite poor compared to free flight. My A2 will glide at 8.5:1 in a non cocoon harness, but I bearly get 6.5:1 with a 'slimline' paramotor on my back (engine off)..... Tick over with the prop spinning just about makes up 10 glide points to about 7.5:1
You'll also 'swing out' more on circling, but keep more outside brake and go slower.
Best UK straight line paragliding XC is 93.46km, best paramotor (engine off) XC is a failed out and return of 27km...... Just staying up in thermals: then there's no difference, you'll just go up quicker PG. It all just adds up to the challenges of thermal flying with a motor. I love it!
all the best,
Richard
