Harry Curzon 1 Posted January 4, 2021 Share Posted January 4, 2021 It seems to be quite normal in other countries to lay a special material over the grass to have a smooth runway surface. However I have never heard of this in Britain, and cannot find a UK supplier using the American trade name. Has anyone done this at their club, and know the brand name in use here? For example, https://www.usfabricsinc.com/products/rcaircraftgeotextile/ https://www.youtube.com/watch?v=X2GzsV6jVL8 Quote Link to comment Share on other sites More sharing options...
Capt Kremen Posted January 4, 2021 Share Posted January 4, 2021 Very interesting, what sort of costs for a reasonable 'model' runway? I have often wondered whether military surplus 'Marston Mat' might make a cheap(er) runway for model flying but perhaps the drainage hole size would not suit all but the large(r) model wheel. Good for the parking and pits areas perhaps(?) Anyone using 'Marston Mat' and can advise costs? Quote Link to comment Share on other sites More sharing options...
2W Posted January 4, 2021 Share Posted January 4, 2021 Golf courses sometimes use synthetic turf, especially for winter tees. Nam Grass is one such product: https://www.namgrass.co.uk/find-a-stockist/ William Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted January 4, 2021 Share Posted January 4, 2021 Trouble is that the subsurface will still need all the preparation and drainage etc. Other factors are possible wear and damage. If a big powerful model noses over or crashes into it , the surface could be damaged or possibly loose threads may develop. Also turbines may well damage it. We considered it at our club but it looked far too costly for our 80m runway Quote Link to comment Share on other sites More sharing options...
David Davis Posted January 4, 2021 Share Posted January 4, 2021 Is this the sort of thing? The club which ran this competition flies off the local rugby pitch during the summer. **LINK** Quote Link to comment Share on other sites More sharing options...
john davidson 1 Posted January 4, 2021 Share Posted January 4, 2021 We keep a roll of carpet in the hut for models that tend to nose over , also edfs which are slow to pick up speed on grass Quote Link to comment Share on other sites More sharing options...
Doctor Chinnery Posted January 4, 2021 Share Posted January 4, 2021 Have seen lengths of conveyor belt laid over grass used for take-offs - not overly impressive, the underlying grass & ground needed a lot more preparation than it received so the surface though smooth undulated alarmingly. Also, although a decent sized conveyor belt looks pretty wide in a factory setting, on the patch it's quite narrow - and don't even think about trying to land back on it!

Dave S. Posted January 4, 2021 Share Posted January 4, 2021 The club I flew with in Finland for some years had a take-off mat which was a used nylon belt from a paper machine. Quite a decent size and free if you knew who to ask. It was useful when the field was wet, I used it for regular .40 size models such as Wot 4 and Sig 4 Star 40. Made taking off a lot easier but it was a small target when landing. Quote Link to comment Share on other sites More sharing options...
Robin Colbourne Posted January 4, 2021 Share Posted January 4, 2021 When the UK had a coal industry, the rubber coal conveyor belts would have been used for this sort of thing. Ther must be other sources such as waste handling facilities which use them. A contact with the maintenance people which install the new belts would be the answer. Here is used conveyor belting for sale: Used Conveyor Belting Terram do a variety of geotextiles in the UK, maybe give them a call?

cymaz Posted January 5, 2021 Share Posted January 5, 2021 We’ve laid AstroTurf. No more rabbit holes Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted January 5, 2021 Share Posted January 5, 2021 Would be very interested to hear more about your experiences with it Cymaz. Especially your views on durability or repair. Our strip gets muddy and wet in the winter being on clay . I think if we did use Astro turf we would need to make a firm properly drained surface beneath which would obviously cost a fair bit.

Mowerman Posted January 5, 2021 Share Posted January 5, 2021 The Reading club have a super flat smooth runway in most winters and some summers, for floatplanes. I remember most regular flyers had floats which could be fitted to their models when required. Quote Link to comment Share on other sites More sharing options...
Steve Houghton 1 Posted January 5, 2021 Share Posted January 5, 2021 What about laying a length of pond liner? Quote Link to comment Share on other sites More sharing options...
Bucksboy Posted January 5, 2021 Share Posted January 5, 2021 We laid at Astroturf runway because of the rabbit hole problem. We were given a used hockey pitch that was being replaced. Used Astroturf is expensive to recycle so they were pleased to give it away. It was expensive to lay, brand new or second hand it’s expensive to lay. However, the Astroturf is indestructible, nothing damages it. Model cars are raced on it, planes nose over and crash into it, it’s as good as it ever was.

Make no mistake.....it’s very very hard work to lay we had the advantage of a telehandler, scaffold pole and lots of help. It takes a little getting used to when landing for the first time. There is not much rolling resistance as you would find with grass. Much of the weight with our turf was sand. there is no rabbit issue anymore. Grass will grow through but it takes several years. We didn’t roll or made the ground level. The turf followed the ground contour, we were going to roll it last year but this never happened. Our biggest costs were buying it and importantly delivery, this stuff is damn heavy Edited By cymaz on 05/01/2021 20:15:11 Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted January 5, 2021 Share Posted January 5, 2021 Thank You Cymaz. I thought it might be a bit too much for us . I think we would struggle to do a decent job. We are trying to just improve our grass at the moment. Quote Link to comment Share on other sites More sharing options...

We gave up and went for it. If you have as severe problem as we did.....no amount of spraying, etc will help. Bury them alive is your only course of action Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted January 6, 2021 Share Posted January 6, 2021 Lol. We don’t have a rabbit problem as we share our land with some keen shooters who seem to keep our furry friends at bay. Sometimes the odd fox does dig in the autumn to for the crane fly grubs which can make a bit of a mess, but even so it’s much less of a problem than water. Some of our float plane flyers are happy though! Our big problem is water soaking and pooling in the winter as our soil is rather heavy clay. We put drainage in the pits area (big gravel filled soak away trench) which was expensive but very effective, but unfortunately cost wise I don’t think we can afford to do our runway. We are considering having a contractor gradually adding “top dressing” (sharp sand mix)to our runway each year to gradually improve the soil. We estimate we will need about 10tons each year for a few years so that is also quite expensive!!

wingcoax Posted January 6, 2021 Share Posted January 6, 2021 We used to have some neoprene matting strips where i worked, designed as non slip and preventing your feet being "drawn" on concrete. About 1.5 mtr wide and as long as you wanted with a yellow stripe down the edges. Quote Link to comment Share on other sites More sharing options...
