Sustainers - Yes or NO!

Post by Scale Police » 19 Jul 2018, 10:05

You will undoubtedly know my opinion on this matter. Moustaches, belong on the men or women that are flying the "scale" model. But, it would be interesting, with this being a "scale soaring" site knowing your views on the subject.

I am so pleased you asked this question in view of the Mynd discussion. I was about to start a thread on this subject myself and surprisingly, at the same time, Chris Williams produced a detailed article in the current version of RCSD.

My thoughts are that sustainers are fine for other forms of model gliding, but when a full size glider never had a sustainer, then there is no reason to add one to your model and then call it a scale model.Gliding is all about testing your skills by use of wind and thermal energy and if a full size pilot reckons the conditions don't exist, then he doesn't fly and that applies to us. No cheating. If you want to fly in poor conditions, build something different

Just because you can doesn't mean you should

I don’t want to fly a scale model glider with a non-scale motor. But many of us do not have access to a slope that is suitable for scale flying, and the nearest tug and suitable flying field is over two hours away. So I can understand why some folks, who want to enjoy flying a large scale glider, would use a small electric motor in the nose which cannot be seen in flight. It is just an alternative method of launching, and for some just that ability to enable flying more than outweighs the loss of scale fidelity. How many scale models are REALLY scale anyway? Many ‘purists’ on this forum use modern wing sections or have enlargened tailplanes to make their vintage gliders fly better - now that might be a matter for the scale police :)

Whilst I would rather only have a sustainer on a scale glider that had one on the full size I'm not so hung up on it if people want to put a prop on one that only (say) had an up and go (or didn't have one at all come to that). I agree that part of the fun of slope soaring is to test your skills when the slope lift or thermals vanish but I definitely test and hone my own skills if I have a prop on something as I can/will hang on to the last possible moment looking for lift before (sometimes) turning the motor on. If I didn't have a prop I would probably never even have launched and so there would be no skill development.

Anyway with the new CAA rules about max flying height of 400ft FROM GROUND LEVEL (not from launch point as previously understood) props on gliders are the least of our problems for slope soaring!!
Our modest local slope is apparently 163m high so if we fly away from the slope we'd have to land or try and estimate what height above the slope (but below launch point) we were flying at INSANE. Lord knows how high the Long Mynd is.....

The answer to this question is yes and no for me. I like a glider to be a glider but I think substaners and fes is right for some. Especially when no tow plane or some sites that need it. I myself am converting my vega to fes but making a dummy nose to make it back to a glider. So with out spoiling the lines of the vega. I have to travel along way to get to a slope so this can be flying at my local flat club.

Should they be used at a Scale Event?

I still want it to be scale that is why I did the dummy nose. It will be flown in that way most of the time. .when the red tape is around the join you will not know.
