Hi Guys, well I jumped on a mates G4 sim the other day, tried the DS, turned some seriously fast circles, and now I want to try it for real. I need the who, what, where and when, for Queensland if possible. I have a ninja....will it ds, or will I need something a little more slippery? and no, I'm not using the Europhia or Evolution....well not at first anyway  . Thanks for your help. Dale, Bundy |

Dale there's a good thread on RC Groups in the Dynamic Soaring forum about what makes a good DS site. It's a long story, describing the ins and outs of DS. The main thing is to find a narrow shear layer between a mass of smooth rising air and a mass of very still air. Classically, a saddle in a razorback ridge with the wind coming straight up the front is the perfect thing. But we rarely have such conditions. I'm sure you could DS the Ninja somewhere ... but it's a case of the plane suiting the site and wind. Then ... there's the setup of the plane itself, since you need to tweak different control compared to frontside or thermal. Much less aileron action and usually more elevator as it winds up. Extra mass becomes a help with DS, assisting with stability and retaining inertia. CG needs to be a bit forward compared to "perfect" frontside or thermal trim. So there's a few tips from an amateur - keep searching, asking and trying - be prepared to demolish airframes too - and you'll get there!

Hey there, As far as the ninja goes it’ll ds but I don’t think it’ll be the best design for it…..that is if it’s the older design balsa glider I think it is? My first time ds’ing was with my bee and can safely say anything other then an EPP wing would have been a right off after the very first circuit! Maybe a better option would be a well built bee or bat? fast enough to learn on and will survive just about anything. If you go with a bee a can give a few pointers on construction to make it quite a bit quicker. Look forward to hearing of your progress  |

I s there anywhere that you guys DS in SE Queensland?
if so how often do you go?
I'd like to meet up with some of you, so I can get some pointers.

Hi Dale,
There are a number of places in the north Brisbane/Sunshine coast area that we DS, but they are all notoriously finicky when it comes to wind strength/direction, they only work when conditions are just so. The best bet is to wait until the wind conditions are good then head out, and even then it can be iffy. That is the hardest thing about DSing in our part of the world.
The Ninja would probably DS a treat, I have a balsa Mijet that DSes very nicely. But it really would pay to start with a foamy - DSing involves flying on the wrong side of the hill through very strong turbulence so until your mind has a good image of what the air is doing back there it's normal to pound into the back of the hill repeatedly. The simulator should help but it doesn't simulate the wildly changing conditions/ ugly turbulence that you can get.
Sean.

I agree totally with the other guys, as a complete novice to DS, I'd have written off many a composite/balsa/ply plane attempting to learn this very challenging & addictive disipline.
Go the foam!!!!!
