210solo

Thanks there had to be some thing that was missing because i could get that calculator to say that lots of thrust could be produced and well under 14 horsepower of power needed but most paramotor engines today have betwen 20 and 30 horsepower to get thrust up in the high 60 plus area as i am 95 kg and need plenty of power .

The main question is what does horsepower have to do with thrust what is the relationship between them.

so then we can work out what horsepower motor is needed for weight of pilot that will have enough power to get off the ground with ease.

This is the link to the calculator

I think most other info came from the Para motoring bible

Hi i have a problem i carnt solve

using a thrust calculator i found on this web site

some figers i put in for the raket 120 engine

Static Thrust Calculator

thrust 76 kg

203 m/s

7.4 horsepower needed

17 miles per hour

standard prop

51 in prop 2 blade

pitch of 6 in

3000 rpm

this shows that the radne has lots of thrust what am i not understanding

i found a prop site that said the radne prop had a pitch 0f 5-6 also top 80.

other info found said said paramotor take off speed should be around 10-

12 miles per hour

thrust needed to maintain flight mutch less than takeoff as the air reaches the prop at a different speed when it is flying.

tip speed of prop must be around .6 mark moor and it looses power

if you increse pitch to 12in flying speed increses to 34 mph power needed increses to 14.8 horsepower thrust stayes the same

so there must be some thing i dot understand as most to 80 15 hp have thrust of around 55 hp

and radne the same 50-55 hp

but i have found some claming to have radne thrust up to 65 kg with right choise of prop and reduction ratio

The big question what factor or relationship does horsepower have on thrust

as the thrust claculator said pitch effects flying speed and power needed and paramotors fly slow anyway

help needed

I wont to use the raket 120 engine for a Paramotor but where do you find out the added power in crease by using the tuned exhaust and tuned barrel and piston etc.

is there some were that supplies this info

would like to know what thrust would you get out of standard unit 14.5 horse power 130 cm prop 3 blade and best ratio to use

please can someone point me in the right direction

I am 95 kg and the raket engine is cheep and lite

I can make Paramotor under 20 kg

hi i have found info and a new tuned exhaust from this forum thanks.

i am after info on fitting the tuned exhaust to a adventure solo 210

i am going to buy it from simonini flying has any one got some photos

any info on fitting it would be helfull

do you ned some type of flang mount from engin etc

thanks

Hi,

I bought mine at http://www.simonini-flying.com/componenti1.htm

Hi i was looking for this exhaust and thanks to you thay still have them but i was wondering do you have any photos of it fitted ect do i need an exhaust flang on the motoe etc how does it fit on i have the adventure solo 210 thanks
