What a huge difference in how the foil feels........................

Just swinging it in the living room and it feels like it is straight, and will kite upright.

The resistance to kiting upright as described in the ealier post is completely gone.

To be clear, the string diagram I used was not the one posted ealier, but one provided by Popad that he modeled in surfplan.

This modeling was for a slightly different airfoil, more like a Clark "D", but it seems to work a ton better than any of the HK set-ups so far for me atleast.

The diagrams are attached...........

I flew this re-strung HK foil yesterday and it performed fabulous. Ended up corkscrewing in due to a unrelated radio lockout, but prior to that it was awesome. What was really cool is; it's been along time since I could run as fast as one of my models in lock-out.

Thank-you Popad, for sharing your schematic................


Sorry, nobody to shoot video................

I'll do some re-building this week, but the status of my electronics.............will dictate when it flies again.

I'll try for some video next time for sure Nadine..............

The Popado measurements are definately the charm for the Hobbyking parafoil. I think the foil is still a great value based on where I'm at now with it. I don't mind the bench time to get something that flies as nice as this.

I'm suprised Hobbyking doesn't just throw a roll of braided line in the bag with foil, and a similar calc. sheet, and say fill your boots.................that is what the pricepoint would dictate.

See pics attached for clarity.......................................
Hei canada_jim,nice work!....what size of wire and from where did you buy it!?
Cheers

Sorry for the delay in reply Nadine...........................I used fly fishing backer line for the re-stringing. It is very tangle resistant and strong for it's size. I have attached a picture below.

I also had good luck with the curved upolstery needles in the picture, they made the re-stringing much easier.

I am stepping away from the flight testing of this parawing, and will resume after obtaining a new radio set. Probaly about 5 weeks from now, others will have to jump on this one for a spring project also. I am standing by with assistance if needed.

Good news, bad news, good news..........

Alright, good news..............................I've recieved my new radio system, and this project was ready to go again today.

The 30km per hour winds did not deter me in the least and off to the field I went. I did fly the parafoil again, in spite of the crappy gusty wind, but the top spar of my gondola flexed and stopped the prop, and a crash resulted. Not before some serious piloting skill was displayed though...he....he.

The dammage is minor, and I will gusset the spar to handle the extra forces from the weight shift configuration.................and there is some good news...

THERE'S SOME VIDEO............................Enjoy.....

Congratulation @canada_jim !

I don't fly if wind is over 20 Km/h.

Good job ! Now, wait some wind under 18-20 Km/h, and you will see the difference.

Try to learn launch from hand, will be very useful.

Happy landings !

In wind like that you were immediately going to have a problem! How you managed to stay in the air was really skilful. Here's to some calmer weather!

Inventing_Man, you bet, it's gonna be loads of fun and it's really a good flying parafoil now. You can see by the even inflation that it's a changed wing.

PopaD, you are wise, but as a seasoned heli-flyer I am alway interested in pushing the edge(safely, without endangering others).........keeps the blood flowing, you know? I am also left-handed, and this make hand launching feel dorky due to mode2 TX configuration. I am still going to attempt to add the "A" assist system to the model to allow launch from layflat.

tedrobphoto, ya your right, but it was invigorating to try. I see you limey's have been hit hard this winter..................cheers to better flying weather.

I have spent alot of time re-building my large gas helicopter, and the test flight is today. Thankfully the forcast is for calm/clear conditions, I'll let you know how it goes...............

I will also update this thread when the Parawing flies again. Probably on the weekend....................

I've been reading this thread with interest, as I recently purchased the belatrike and HK 2.15m foil. A couple days ago, I checked the line length on my canopy and discovered that it's utterly inconsistent, both with the line dimensions suggested on HK's website and even side to side. It's as if somebody just tied them randomly. Some distances are off by more than 10cm from the lengths they should be.

From reading this thread, I'm guessing that there's no point in even trying to fly this, that the only thing to do right now is start restringing the foil, right?
