    Big wings like mine (28 m) create more drag and hence use more fuel. Likewise, big people require more fuel.

    so is there a wing that is

    easy to launch 

    stable in the air (hand off flight) 

    fast in the air 

    agile when you want it to be 

    slow takeoff and slow flare 

    i guess if such a wing existed there would be no need for any other wing on the market

    I did a quick calc the other night... in still air, I am getting between 40 and 50 mils per gallon which tickled me :)
    somewhere between 2 and 3 liters per hour (best calc has me at 2.2lph if I fly like my granny)
    23m wing and an old Bailey V2... weighs 45kg with reserve and fuel so its not all smiles :( 
    Because of the "air speed / ground speed" anomaly, its not useful to measure efficiency in distance traveled.

    Also, you climb rate will be the same "down wind" and "upwind"... it seems you have hung onto the optical illusion created by the differing ground speed at low level EG: the "climb angle" is steeper into wind and more shallow "down wind" but the rate of climb will be equal given the same rpm etc.

    oh really ? i wasn't aware that upwind or downwind would be the same climb rate at the same throttle position, thinking about it, it makes sense, as the wing will always travel at a given speed as hann mentions above.

    so what your saying is a need a bailey lol 

    Im glad i asked the questions now as im learning alot more thanks guys

    Picking up on a few points that stood out;

    Yep, 6.9L/hr for that motor is far too much.

    Do makes lie? Maybe not lie but their figures are probably on a test bed not during actual flying, not that it should make that much difference because a PPG motor putting out 30kg on the ground will be very similar to it doing it in the air (as long as you keep a constant speed and not constantly climbing/losing altitude)

    How are you doing your plug chops?

    To get an accurate indication you`ll have to run the motor at cruising speeds for a while, then kill the engine and glide down so that the plug shows the actual running conditions during cruising speeds not just the last 2 minutes when you were at idle/low speeds lining up for a landing.

    Is it a Synthesis LT (original Synth)? They were renowned for being a bit of a lardy ol` bus with similar efficiency..

    Once your feet leave the ground there is no `wind` - you are simply flying in a moving air mass - flying into or with the wind only affects your ground speed, your air speed on a PPG is always the same (for any given trim setting).

    Have you got a tacho fitted?

    Knowing where you are in the engine power/speed range might help.

     

    I suspect that your motor is not as well tuned as you think - an engine temp of 120-125 is very low and is an indication of a very rich mixture.....

    hi yes the engine was running rather cold however it was very cold up there that day, but looking back on previous flights it does look like im using around 6 litres an hour, 

    i mean if this is normal then i will accept it and just take more fuel with me but it does seem a little much for a 100cc engine to use 

    i have not plug chopped yet but i do check the plug rather often to make sure colour is not greying or white, and i normally run high rpm then stall the engine and check that but what your saying to check at mid throttle makes more sense so although i'm running "right " top end i may be rich in my mid throttle, i will check this one out on the next flight. 

    thanks Harry

    Thanks mate. :-) I too had an amazing weekend!! :-)

    Keep your eyes peeled for information about the next one. 

    SW :D

     

    hopefully i will be able to rsvp for this one before they all go, 

  5. so i had 6 litres of highly flammable liquid in a sealed plastic container, this, according to the manufacturers specs should have gave me between 1.45 and 2 hours of flight. The plug being a lovely coffee colour shows the motor is running as it should.

     

    So im happy to take of with my 6 litres knowing that i am safe for 1.45, i fly, i do my thing, i return, I overshoot my landing and roll on the throttle, to a splutter bang pop, (and thats just my arsehole). It turns out that i had consumed 5.75 litres of fuel in what turn out to be 50 minutes, i manage to nurse it to a safe controlled landing, smiling at the amazing flight i had just had. however on the way home i started pondering. 

    A. how efficient is my motor

    B.how efficient if the wing

    and 3 lol. how inefficient does the wind make us all 

     

    so now lets go into a little more detail of the three options 

    A I fly a vittorazi fly evo 100cc if creates 56kg of thrust and its enough for me at 75kg. the spec states that it uses 3.-3.5 ltr per hour at around level flight (30kg thrust), so the motor i have if pretty much perfect for my weight, so either

    Do the specs lie ( are vittorazi actually in partnership with those sneaky german car  manufacturers that manage to trick the world to believe there engine is more efficient). 

    Am i using to much throttle, and by this i mean am i being inefficient in my throttle usage? (maybe climbing at full chat and then going to tick over) kind of like the way  the way our mums would drive causing everyone in the car to suffer small scale whiplash ?

    Is my motor not really tuned? I have tuned the motor to where i believe it should be, the plug is a nice coffee colour with a very slight oil build up on the base just near the electrode, showing my oil mix and air to fuel mix is correct. (i also have an in flight tuning mod to the carb, which i have not used since i got the motor running smooth) 

     

    B. I fly a 29 synth ( i know the thing is a boat, and last time i saw fabric that size  i decided to leave the canadian girlfriend and head back to england) however i am in the correct weight range of the wing when taking into account the motor fuel reserve etc. 

    would flying a smaller wing increase my fuel consumption as i will be flying faster ? 

    or will it decrease as the newer wing would be more efficient (even though it would fly faster) 

    Or is the fact that i shit myself on every launch the problem? does the shit hit my prob and disturb the airflow causing less thrust and making me use more throttle to fly

     

    and 3. going into wind. ok i understand this would slow me down, but it would also create more lift, therefore i would not need as much throttle to maintain a steady flight.

    going with the wind would give me more speed but i would need more throttle to maintain height and this is where litres per (distance) would come into play

     

    so i will post my flight details below and look forward to hearing some answers back, (i don't mind having a laugh and reading some hilarious answers but some sensible ones would be great to please 

     

    Flight location oh fuck .... here we go.... (sorry guys) Parafest.........(i know, i know, but in my defence i wasn't made aware of the summer fly in rsvp so i missed out) 

    wind speed 2kph On ground around 12-15 kph in air 

    air temp 12 but i was freezing my tits off up there

    distance traveled 36 km 

    fuel used 5.5 - 5.75 litres

    max engine temp 120 - 125

    max height 2028 feet

     

    so whats the conclusion here.

    am i just a fat fucker, 

    is my motor letting me down 

    or do i need a new wing 

     

    look forward to the opinions of others 

    and and Paul ....... no talk about your bailey please Lol

    Too early!! ummmmmmm 

     

    Oh shit..... I could not find this anywhere.  Gutted. Any chance of two more spaces ? 

    Ok i may as well ask now. The autumn bore chasers this autumn, do we have dates ? I need to learn how to navigate this site 😂

  7. so basically just a bad judgement on deciding to try to launch rather than an actual failed launch ? 

    i wasnt sure if maybe i felt lift and lifted my legs or if i tripped over, i just remember running like hell and then hearing a big bang (prop hit something) either ground or my fuel tank. then lots of vibration (unbalanced prop) so i killed it and started skidding on my feet to come to a quick stop. 

     

    im surprised no one has any footage of it though, im sure it would have given some people a laugh.

  8.  

    Hi, im looking for anyone that may have video footage of my failed take off/ crash on the sunday morning of the summer fly in, 

    set up was a bulldog with a red synth, and ended up with the prop going through the tank strap, 

    Im not quite sure how it actually happened as it all happen pretty quick and would like to review the footage and also stick it on youtube ;-)

    also here are two quick videos of the weekend 

    Enjoy.

     

    this one was my first flight of the weekend, and my first engine out 

     

    this was my second flight of the weekend, the first flight with an engine out is below

  9. is there a there a thread on here that shows where we can fly I'm looking at a lot of maps and they all read different, I have a friend who says I cannot take off at canvey at all this is southends airspace, and I have spoke to people who say you can, and maps to show we are outside of southends class d airspace. 

    that website abopve just give updates on cranes and events happening in the air over the next week doesn't it ? or am I wrong ? its quite possible :)

    Hi Harry,

    First bit of advice, buy this and almost all your questions will be answered https://www.paramotorclub.org/store/product/5-paramotoring-the-essential-guide/

    1. It's Class G airspace for us. I have flown from a Class D airfield but that is unusual.

    2. Yes to flying from one location to another, avoiding restricted airspace. You don't need to file a flight plan for Class G airspace but prior planning is highly recommended. You will need an up to date air chart or GPS so you know where you are and what restricted airspace you need to avoid.

    3. You don't need to be in a club for paramotoring, the training cost with Simon on here is about £1100, this is a typical price but Simon gives training until you are competent to fly alone. There is no license in the UK for paramotoring, unlike France where it is included in the microlight category.

    4. Look at the Classifieds on here for good 2nd hand kit. Beware of used wings on e-bay, particularly as a newbie .

    Alan

    hi thanks for such a quick reply. I will order the book now,

    I'm trying to currently get my head around aviation maps and where the class g is, I have read that class g is also below the class e 

    is there a map online that shows for the most part  where we can fly, would it not be easier to use colour on a map to show the different areas, I know a lot of the airspace overlap so you could have class a as yellow class b blue and where they overlap its green, (all of this to make it easier for me lol) is there a tutorial video anywhere or will this be covered in the book you suggest ? 

  11. Hi I'm from Canvey Island Essex. I have been interested in flying for many years and after having a gliding day I decided I will seriously pursue this hobby, I have done some research on cost etc, and ppg seems to me the cheapest form of powered flight, without the huge tests that usually go with means of flight.

    lets just jump in here,  I fly quadcopters (built from scratch) not brought from a store. so I understand the laws that we have to abide by, and the dangers involved with lack of maintenance, common sense and complete disregard for rule and safety of others. Not to mention the danger to the sport just because someone took advantage of somewhat relaxed rules.

    I have a lot of questions so lets just start with some basic ones, (I have done some looking around on the internet but nothing seems to be a solid answer in this hobby.

    1. what class airspace can you fly in and launch from, here on canvey its class d, is there any free maps online that shows the airspace classes that are clear to read?

    2. Is it possible to fly from one location to another lets say for example Essex to Yarmouth, with a flight plan, (or do you need airspace permission, along with support team) is it possible to go around the no fly zones to get to a destination?

    3 obviously I will get training before attempting to fly, so whats the cost of training to be able to join a club, and are there different levels of licenses for this hobby?

    4. i will keep this as the last question and add to it as I get more answers, I'm on a budget and I know I cannot afford to buy all the equipment new. Therefor I will have to get into this hobby using used stuff, my last question is, is there a big saving by buying off of ebay, or some other used selling site, or shall I buy my used stuff from a reputable shop or trainer, and if I bought say from ebay, do I need to get it inspected by the loft before I'm allowed to fly from a club site?  

     

    I hope this post will help out others wanting answers to these questions to. 

    thanks for any replies in advance 

    Harry
