  1. I agree with that ...... Weight becomes an issue very fast.
  2. This is the idea that I had . Hopefully the sketch explain it better
  3. The idea to use an electric motor in tandem is not to be able to fly with it ,more to help with take-off. If you use an motor as I suggested you could use an 2kw motor and when you use it , you could over load it up to 4-6 kW for 30 seconds with no problem ,then you are up and it can cool down In this time you would empty all power from the "batteries". I would use a Brushless 3 phase motor because the are compact ,light and efficient (in the monster efi system they use that same idea with a 3phase Brushless motor for power ) My ppg engine I would use would be a top80/atom 80 size to keep it very small, charging would be at properly at max 500 watt ( let it charge over an hour to no affect performance)
  4. Hi My thoughts. I would not use the "paramotor " engine for power ,they are not design for that, service intervals would be almost every week depending on use......... If you look at the Honda gx200 engine that gets used in the "egg motor projects "and for racing. It is designed to run at around 20 percent of full potential ,at that it will happily run for years, gets used in everything . If you take the same motor , change piston , conrod, etc you can get it up to 22hp. At this power output you would have to service /rebuild it almost after "every race " as it gets used at it limits. This is the same for all aviation. A car engine runs at about 20 percent power while aviation engines normally run at 75 to 80 percent power , this is why service is done regularly.
  5. To get any to of my messages ,sign in, etc I change from mobile to desktop version on my phone.
  6. Casey, We became dealers for the Paracell a year ago We are just about to order a couple for a TV show I am working on in the future. SW Simon, send me details Casey
  7. I had a bigger prop once, slipped on takeoff and broke it, this one I have not yet manage to brake, even with a few crash landings
  8. Hi Alan This is my jpx330 on a zenith frame, been at PMC fly ins a few times, heavy but reliable and cool.
  9. Steelmesh I would use the propellor hub/pully assembly , use a brushless motor, redesign it and cut grooves on the outside of the motor to run the drive belt over it - use the motor body as my redrive pully. These motors work very well as generators, that is how motorbike alternators are design (3 phases with a 3phase rectifier to get it to DC) That makes it very compact. I was looking into building an electric paramotor and gave up after calculated that I need at least 287 lithium 18650 cells to get to at least 30min of flight time, and make it reliable.
  10. The best way to approach this would be to get a small paramotor engine (belt driven with clutch) and convert the propeller drive pully to a brushless electric motor then you could then run this as a hybrid , you could use that motor as a 3phase generator, for charging when you run the engine ( charging would have to be closely controlled or you would overload the engine). When the engine is stationery, the centrifugal clutch would disconnect and you could use the motor or you would be able to to use them together as well. There would be quite a bit of electronic's and separate controllers involved to control and switch everything Alternator is around 75% efficient Motors is around 80 - 90%max efficiency if you are lucky Current draw at 72V , 13 kW =185amps Heat, loss, bearings, electronics, batteries, charging, etc will add even more losses Hope this make sense, this is how they are integrating drone engines/motors. They use the motors to help with take-off.
  11. I have been wearing hanwags, I am a size 8 but have to buy them in size 9. When they are new they are so stiff that I have to undo them to drive. I walk through my soles after 3 years of everyday use. The best investment I have made, saved my ankles on many hard landings. I love them
  12. Hi, checked the values My cht and egt uses the same thermal unit, you could swap them around and they still work perfect 27 degree's Egt : 4.42 ohm Cht : 4.42 ohm 100 degree's Egt :4.58
  13. I have no idea what the resistance is, will see if I can get hold of a meter to check it.
  14. I have not seen the O2 work on the 200 but suspect they put it there to get out of the flame path. When I got it I was told that they had only 1 hotspot after tuning it. It was running grey on the spark plug. I fitted a FLY HENRY unit, egt sensor in the bung and it gave me the exact same spot, it is very sensitive, you can actually see the exact start of the leaning out and as you add throttle you can see where it stops.
  15. This is where I got it fitted on my eos. I have a Polini thor 200 with an o2 sensor bung and it was fitted at he bend around 200-250mm from the engine, I fitted an temp sensor and it work very well there.
  16. Thank Scott Spoke to Robert
  17. I have one of the first generation eos150's. My temp running is between 228-234 degrees under the spark plug, 545 degrees exhaust temperature. I have to be carefully on the throttle or my cylinder head climb to over 250 degrees very easy while my egt stays fairly stable. Spark plug is light black I use around 6 liter an hour trims out. (roadsters 26)
  18. Need some advice : I have one of the first generation eos motors Who keeps eos150 parts in stock , need a new pullstart, mine stop working (catching) over the weekend.
  19. I took it out last year around September. I contacted the PMC insurers and they told me that it did not cover Spain. I am now covered for South Africa as well. Have a full SAHPA licence witch covers me third party as well When I got my new wing, I told them and they added it. It also covers me free flying that wing : (£5) document change cost
  20. Got axa as well ,needed it for Spain..

    BORECHASERS 2019

    If my calculations are correct my flight times for the weekend. 400.04 km total distance 14.29 hours flying 77 liter of fuel used Casey Thanks to PMC for the best weekend ever!!!!!!!!!!!
  22. Have anyone perhaps done some free flying with the ozone roadster 3 ,I would like to find out how it compare to a PG wing Casey
  23. It is such a lovely place to fly . Done that last year
