Simon Chaddock Posted November 12, 2009 Share Posted November 12, 2009 PaulAre you sure the model is doing this by itself or are you making an instinctive input as it apparently speeds up or slows down relative to your viewpoint on the ground?

Paul Adams Posted November 13, 2009 Share Posted November 13, 2009 Have decided that the wind forcast for tomorrow morning may be too strong to fly in. The forcast in the south is storm force 10. Quote Link to comment Share on other sites More sharing options...
Aero120 Posted November 13, 2009 Share Posted November 13, 2009 The real problem is the location. Slope soarers can fly in high winds as they are usually on a hillside with clean air flowing over it, so as long as the model has an air speed higher than the wind's ground speed its okay. However for those who fly from a flat field with power, the wind generates all sorts of turbulance from trees, hedges and even the club shed. So when you fly, the rolling turbulance can smash your plane into the ground, irrespective of your ability or your planes power. Plus if the wind is too strong once you land your model it can be blown away as my Fantom was, breaking off the fins as it was blown end over end down the field after a safe landing!

Tim Mackey Posted November 13, 2009 Share Posted November 13, 2009 But thats only true as far as actually "flying" is concerned, slopers still have to contend with some wicked sheer and turbulence when launching and landing. Quote Link to comment Share on other sites More sharing options...

Mmmm wonder why they call one of the slopes at The Bwlch "The Wrecker"...............Edited By Frank Skilbeck on 13/11/2009 22:50:44 Quote Link to comment Share on other sites More sharing options...

Dave Bran Posted November 14, 2009 Share Posted November 14, 2009 Posted by Phil Wood - Moderator on 13/11/2009 23:15:14:Nah....slopes are nice things...they always bring your model back safely.Polyphilla. Excellent, helpful, that............I'll ignore the signs and send my pupils bills to you then.................... Mostly, feel it's all been said now, hence the ribaldry/etc.........but for my 5p's worth, while I'm quite happy flying slope in anything less than around 40mph (with the right model), I would not fly my local club field with power versions of the same plane (FW Buzz, Buzz Lightning, Slipstream, etc) much above a mere half that, as the sudden stabs of turbulence are far too violent for safety. Flying the Tango there the other day, starting at about 10mph, a plane that copes with wind far better than it's appearance might suggest, but the wind eventually rose over the 25mph level and the upwind erratic shaped tree line started causing extreme instability in the airflow, so time to land............ I usually try to use my windsurfing windmeter, BTW....as subjective estimation is VERY imprecise. Quote Link to comment Share on other sites More sharing options...

Phil 9 Posted January 29, 2010 Share Posted January 29, 2010 If I cant stand still without my had blowing off it is too windy Quote Link to comment Share on other sites More sharing options...
flytilbroke Posted January 29, 2010 Share Posted January 29, 2010 Slim, fast planes often handle better in the higher windspeeds. The day I mentioned earlier had the Turbine Jet jocks fairly happy when a lot of the more "mundane" models stayed firmly in shelter. Really as has been mentioned it is the Pilot and model combination which dictates flyability. On open sites the wind tends to be steadier, less turbulant. I flew off the Beach at Ainsdale with the Southport lads, in a good breeze, which some of the lads thought a bit strong. Like flying on rails compared to what I was used to.

enrico Posted January 29, 2010 Share Posted January 29, 2010 This plan built Jart is 4 lb and i don,t launch until the wind is 30ish.The hightest windspeed ive seen on the windmeter while flying is 68-71 mph.Still flew no problem. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 29, 2010 Share Posted January 29, 2010 Ooooo jartiness. This is my LT and she now weighs in at around 2lb 14oz. Flies well in anything from around 15MPH to about 40 MPH Edited By Timbo - Administrator on 29/01/2010 22:02:54 Quote Link to comment Share on other sites More sharing options...
