Hello all,need to pull the line out when we are about to hook up to a glider.
Our club has been operating a Pawnee with a Tost reel system for some years now. For the most part it works well, but it does have issues. It is not uncommon for it to jam on line retraction. Our biggest concern is the amount drag and amount of force
I'd like to talk to members of other clubs/operations that use the reel. I know the St. Louis club uses a reel system and that Williams Soaring does also. What other clubs use a reel? What issues do you have? Have you done any modifications? Do youhave the same issues we have?
You can contact me off list if you wish at mfpalme AT gmail DOT com .

That's unfortunate. Our club, (in Minnesota) operated a PA18 with a custom reel made by a master engineer club memberneed to pull the line out when we are about to hook up to a glider.
years ago.
The STC paperwork and winch goes with the supercub, which is for currently for sale.
But I don't think 160hp would work out well in Colorado.
We should have developed it into a product - apparently it's still better that Tost as we had none of those issues.

It's good to hear every one else's experiences. It seems that the line fouling one way or another is not uncommon. For us, lately it has become very common, and thus my concern.obviously. We're experimenting with some sort of bungee setup that the line crew would hook to the line while it plays out. We do not hook the line to the glider and let the towplane taxi away. This is because the line hangs and jerks and (more often
Hartley notes that they hook up the line to the glider and then let the towplane taxi away while the glider holds the brake. We do not do this, instead, the line crew holds the bullet while the line plays out. This puts a lot of stress on the line crew,
So how smoothly does the line extend? A couple of years ago I was at the Women's Soaring conference in St. Louis. They have a reel on their Pawnee and the line always seemed to extend smoothly and easily. Ours has never acted like that. We're currentlyusing the 6mm CRG rope from W&W. We've also tried a 4.5 mm poly rope. No difference.
Bumper, you might not be in the building business any more, but if you had any pictures or diagrams, I'd love to see them.

Hartley,
I believe it's the standard 60 meter reel but I will check. I know our IA and Chief Tow Pilot have disassembled and check the entire system in the last year or so.
If the line paid out smoothly I think we'd have less objections from pilots.
Thanks,

MarkMark,
Sorry, I have neither. I didn't put the project to paper as far as diagrams or blueprints, just sort of built it to fit with quite a few visits to the Pawnee with a tape measure. I did do what amounts to a tech write up for the FAA, that included
Our procedure was to stop the tug a reasonable distance from the glider to prevent sand blasting and let the line crew pull the line and hook up, test the release etc. Then taxi away to pay out the line, no problem. Payout was actually too easy IF themotor leads are not shorted when off (my first tow reel had the motor leads simply shorted by the motor power switching relay when off. This proved to be too difficult for the line crew due to too much braking action. A suitable resistor was then used in
