Hi,
Have got myself a miniwind turbine and I have two sets of blades (3 blades) with blanking caps in a six hole hub. It also has pitch pins which locate in the blade root and set the blade pitch. Anyone have any idea of which pins to use, ie what is the rationale behind which pin set to use. I understand the idea of changing the angle to adjust the blade. What i am wondring about is there a rule of thumb for which pitch to use with which wind site. I am north of Scotland , elevated positon, 1000' facing W with no obstructions, so pretty windy spot. There was nothing in the literature that i was given which mentions the pins, other than to put them in!

Hi Alan,

it's a long while ago and my memory is pish but I fitted a Futurenergy 1kw once for a mate, it came with two sets of 'pitch pins' 21degrees and 25 degrees, pretty sure that the 21 degree pins (finer pitch) were the 'North Scotland' ones  Grin However I'd phone them up, unlike Miniwind they answer the phone and emails. Be interesting to see how you get on with it Eleanor had one but it was seriously noisy apparently.

Cheers, Paul

Thanks Paul,
gave futurenergy a ring, and basically the windier the site, the shallower the pitch and vice versa, so will go with the lowest ones first and see what happens.
Yes i know eleanor had problems with hers, I have no neighbours...

I liked the miniwind design, bit optimistic with power output but otherwise a good design, decent price as well.
Also like the LE engineering down wind designs, again at realistic prices, a bit like a proven on the cheap...............

Yes, I like the Miniwind too chaps, yet another turbine without slip rings that seems to get on just fine. I was looking at them again recently but they're just not big enough for what I need and I was put off by the companies lack of response to phone calls and emails. Not just mine I might add, others had found the same  Roll Eyes Futurenergy on the other hand seem to bend over backwards to help their customers.

Honestly,
         In this day and age,to have a turbine with out sliprings is inexcusable.it is seriously flawed economy.

Hi Paul, yes i have had difficulty getting in touch with miniwind too recently. I did contact them several times a couple of years ago and found them helpful, but i seem to recall Gordon may have had some difficulties and since then it has been difficult to get any response. A bit unfortunate really as i like the design. As Dave said, a bit like the proven but at a reasonable price.
