  1. i am not a dzo but i think in order to make a twin viable these days it needs to turn around 40 minimum efficiently. because there are singles that turn 20 efficiently now. and 40 per load means a lot of jumpers on the dz so that means only the largest events. a 30 year old dash 8 100 series combi converted for skydive would carry almost 50 and with 1900hp per side i think would be fast up and down! but they must be 5M at least also. i think the supervan or similar alternate (single) will be around for some time.
  2. cruises at 200kts and 3300ft to take off. it is mainly for cargo from paved runways i suppose. not a tough STOL bush plane like the twin otter.
  3. or just get a regular bag with rubber bands. i am not yet a fan of the semi stowless. but in any case, here is a u tube video i believe by upt... https://www.youtube.com/watch?v=kL-gHvdubac
  4. rear cargo door is not narrow. https://www.airinuit.com/en/fleet/bombardier-dash-8-combi-100-series modern day dc3...except could it carry ~47?
  5. a local very experienced rigger when I asked of all the low pack volume reserves which one has what looks like the most rugged tough construction his answer was the smart lpv. so if i were to venture from my tried and true pdr into a low pack volume reserve I would go for the smart lpv. but I will stick with the bullet proof pdr.
  6. a dash 8 100 series was jumped in ontario a bunch of years ago. no i did not get invited! would the largest dz's every be able to use one? i expect it may not be economical... DHC-8-100 series Original 37–39 passenger version that entered service in 1984. The original engine was the PW120A (CAA validated on December 13, 1985); later units used the PW121 (CAA validated on February 22, 1990). Rated engine power is 1,800 shp (1,340 kW).
  7. sabre1 with a dome slider from skyworks rigging is overall a very good canopy.
  8. you are making no sense....i think i am done following this. there are very good videos on youtube to help riggers. i used to copy this video and send to anyone wanting it,,,free. now there is youtube. https://www.youtube.com/watch?v=smEzRl5grtk
  9. mel with all due respect, and i agree with your other 'no goes' (Optimum reserves and Wings containers) but if you are going to dump a reserve into a spinning main you cannot blame the reserve bag line stow configuration. you are simply rolling the dice. keep in mind john lebanc at PD recommends large rubber bands and double stowing ALL main stows. how many very experienced people have you heard telling new jumpers not to do this out of fear of bag lock. the bag lock thing is a myth. overall, it is more important to control the lines until line stretch.
  10. i would have absolutely no issues using the reserve speed bag. my rig is just old so does not have one.
  11. i use the speedbag for my main for years. no issues at all.
  12. p750 was based on the Cresco....shown here.
  13. plane was sold to a Chinese customer, then resold to a thrid party and then flown into n korea.
  14. major pilot shortage now and in future (in china). And about 30 percent less cost. https://www.suasnews.com/2017/10/finally-delivery-drone-makes-sense-pac-p-750-xstol/
  15. there are 2 stories,,,not one. 1. PAL sold a plane to a Chinese customer,,,they resold it to a third party who flew it into n korea 2. china is converting the p750 into cargo delivery drones
  16. nancy or someone from JS should be replying here. i sent them a note.
  17. like was stated above. whenever you see the elastic keeper torn, it is most likely a packing error. the catseye was not pulled down below the ring. it is more common than most think. people really do not know their gear it seems.
  18. they may not have a catseye but that does not mean the brakes are not set for opening. the tail is pulled down in full flight on icarus tandems. it is a compromise that works out well.
  19. I do not but it can climb also... https://www.siemens.com/press/en/feature/2015/corporate/2015-03-electromotor.php?content[]=Corp translates to 2264 ft per min edit...fascinating stuff! https://www.youtube.com/watch?v=Xe1g1JrRRkY
  20. from wikipedia (260kW is 348hp)....but yes the battery/fuel cell issue... 330LE The Extra 330LE is a one-seat aircraft powered by an electric engine made by Siemens, delivering 260 kW, for 50 kg. On Thursday, March 23, 2017, the Extra 330LE set two new speed records, said Siemens : "At the Dinslaken Schwarze Heide airfield in Germany, the electric aircraft reached a top speed of around 340 kilometers per hour (km/h) over a distance of three kilometers. On Friday, March 24, 2017, the Extra 330LE gave another premiere performance by becoming the world's first electric aircraft to tow a glider into the sky". [5]
  21. for the best balance of risks, PD recommends double wrapping all stows and using 2 inch rubber bands. edit,,,of course this is not a PD but i tend to listen to everything they have to say.
  22. Oh but this so you don't HAVE to have a tight loop that is to inconvenient to pack. AND you don't have to worry AT ALL about moving in the airplane. Of course why even have a main when you won't use it most of the time? WAIT, put it on the reserve so you don't have to check that either! ( For those that don't understand sarcasim this is it.) And to the guy with 2000 jumps who wondered why all the responses were negative figure out which way a main bridle usually pulls, and pull a nirmal straight pull out pin and a normal curved throw out pin in that direction. Then stick a big add bolt through the loop to simulate this killer. Then maybe you'll get it. Thenthree piece hinged pin we thought it was is a better idea. Not much but some. being an engineer,,,,what i am saying is lets see the test results. the pin is curved just a tighter radius and not to the extent of the curved pin we all know. i could be wrong but i assume it has at least a couple thousand jumps on a bunch of rigs prior to being put on the market.
  23. i would be interested in real results. lets see a picture of the wear. and what issue are they solving. i suppose it is supposed to be more secure than the curved pin since the loop sits down inside the grommet more,,,harder to simply push it out in a direction parallel to the backpad.
