mgrant Posted May 24, 2010 Share Posted May 24, 2010 My mate has a new 9 litre tank the same as in the Racket 120 home build thread if it any good to you. £ 15.00 posted. Quote Link to comment Share on other sites More sharing options...
fanman Posted May 25, 2010 Share Posted May 25, 2010 Hoping this is a different one to the one I have already paid Graham for Quote Link to comment Share on other sites More sharing options...
mgrant Posted May 25, 2010 Share Posted May 25, 2010 Ha Ha! Don't worry it's another one. I forgot to give the tank to Graham on Sunday but I dropped it round to him yesterday so you should have it soon. Quote Link to comment Share on other sites More sharing options...

gazgrace Posted September 1, 2010 Author Share Posted September 1, 2010 hi all a little update . I took the raket home build out today for it's first flight . well it did fly a little , There did not seem like there was enough power . I don't know yet what to do it should of got me up better than what it did . So could a different prop make that difference and where would I get a 130 prop from for the raket ?. not sure if I have the right reduction drive ratio . some pics of my paramotor on forum if any onecan tell from them.Or to get a tuned exhaust . any opinions what to do . ? Thanks Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 1, 2010 Share Posted September 1, 2010 Is the engine reaching the max RPM ? Over pitched =lower RPM Under pitched = higher RPM Quote Link to comment Share on other sites More sharing options...
gazgrace Posted September 1, 2010 Author Share Posted September 1, 2010 some one I know is going to check the rpm to see if it's right . so you think it may be the prop ? Thanks Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 1, 2010 Share Posted September 1, 2010 Possibly, its the first thing I would look at Quote Link to comment Share on other sites More sharing options...
gazgrace Posted September 1, 2010 Author Share Posted September 1, 2010 once I figure out it's rpm and changing the prop where sell them ? and if it's over or under pitched how would I figure out when I go to buy one to get the right pitch . I don't know much about pitch and how they do that may be the lad I know does as he's been flying for some yrs now . Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 1, 2010 Share Posted September 1, 2010 I dont know how to work out the pitch so when I was playing with mine I got an adjustable one from GSC props in the states, but it is a heavy prop. you can get carbon adjustable ones as well but if you can find some one to work out the pitch you need then a fixed pitch one would be the way to go Quote Link to comment Share on other sites More sharing options...
gazgrace Posted September 3, 2010 Author Share Posted September 3, 2010 well i think i have figured it out . its a 3:1 reduction drive. but can any one tell me where i can get a 130cm prop for the raket for that reduction drive .. thanks .

Guest Posted September 4, 2010 Share Posted September 4, 2010 Hummmmm, I seem to remember that the largest that you will find is a 125cm prop.... I may well be talking poo though. SW Quote Link to comment Share on other sites More sharing options...
