    Prop size for Kyosho Soaris glider?

    in General Electric Flight Chat

    Posted

    Hi Timbo-Just to let you know I checked out Puffin models, and a few others around the globe for availability and price and indeed they do a real good deal. In fact I gave them a call yesterday and ordered two spinners and a few folding props, (I have another powerd glider on the go as well) Postage was extremly reasonable, and  a good reception from the staff. Thanks for the tip.-Jim
     
    PS  HTH ??? ( I'm not too familiar with this chat short hand.)

    Thanks for the advice Timbo. I’ll give an 11x6 a try and see how many amps she draws. I have a tong amp meter I could use. I have heard that it should be connected round the plus lead between the battery and the speed controller, is that right?

    As for using a 3s LiPo as opposed to a 2s to keep the diameter down, I reckoned that with a 3s I would get more revs (KV x volts) and should reduce the diameter so as not to overload the motor and speed controller. However I’m pretty new to this electrickery stuff and might have got it wrong.

    As far as determining how many watts the setup draws, isn’t it just a matter of multiplying the volts the LiPo gives times the amps shown on the tong amp meter, or is that oversimplifying things?

     Another thing I’m not too sure about is that the bumf that came with the motor states it can be timed between 20 and 30 degrees??? What does that mean, and how do I go about changing the timing?

    I’ll have a look at Pufin’s spinners to see what they’ve got, though I will have to see what cut the GPO (do they still deliver post?) takes as I left Manchester many years ago and now live in Stockholm, Sweden.

    On another note, I must offer my sympathy having red about the incident with your Jart………It’s surprising how crowded the airspace can get even when there’re only two models flying.

    Keep up the great work with these threads; it’s a great inspiration, informative and entertaining. I only wished I had taken up flying whilst I lived in England. My parents lived in Devon and when I see what great slope soaring sights you guys have access to I can’t help but feel a little envious. The only consolation I have is our clubs annual sojourn down to Skone in the south of Sweden. That’s where you have to stop to avoid getting wet before hitting Denmark. Those sea breezes are just incredible compared to the slopes we have where I live.

     I am in need of some advice. I bought a second hand kit, a Kyosho Soaris Spors motor glider, at a swop meet two years ago and I'm just getting round to setting it up. I have an EM Cyclon 30 class outrunner I am planing to use and I have a 60A Turnigy speed controler which I hope will be up to coping with the setup. Acording to the spec that came with the motor it will take 25A continuous and 35A peak, with a 20 degree timing.I am thinking of using a 3s LiPo to keep the diameter of the prop down.
     
    What I need to know is what  prop diameter and pitch would be suitable for this set up?
    Next question is what make of folding prop is the best . I've heard that motor load and performance can vary for two identical props of different makes. The diameter where the nose terminates is 42mm, so I suppose a 40mm spinner is what I should be looking for?
     
    I'd be grateful if any of you guys can give me some advice.
     
    Cheers, Jim

    CHRISTMAS GREETINGS THREAD

    in Chit-chat

    Posted

    I’d just like to add my Christmas greetings to every one, not forgetting all the staff at RCM&E who after all made this sight possible.Keep up the good work.

    Have a very merry Christmas and a happy New Year, (or should it be the other way around)  

      From a not so snowy Sweden (in fact it’s raining cats’ n dogs and reminds me more of when I lived in Manchester)

    Pick a Plane: shortlist

    in RCM&E Magazine

    Hi Tom,
    O.k. my choice in order of preference is,
    1: Hawker Hurricane.
    2: Hawker Typhoon.
    3: Miles Magister.

    Motivation.
    When I first started looking around for a WW2 fighter modell to build I was of course attracted to the Spitfire. (like every one else). But then I read an article in RCM&E for a 40 size Hurricane kit. At first I thought the Hurricane was a bit ugly and agricultural. However the more I looked at it the more the ugly duckling syndrom got me and the Hurricane became more and more atractive. The kit revewed in RCM&E was no longer available so I started looking for drawings (I'm not much of an ARF fan) but couldn't find any good drawings for a 40 to 91 size modell.
    After meeting and talking to Dave Knot att the Swedish World Scale Modell Championships, (I'm an exile Brit living over there/here), and studying his modell I just had to build one of my own. So if this turns out to be the modell chosen for the RCM&E build I'll be more than chuft.(If retracts should be an option then this modell will take a lot of beating)

    Prop selection

    Hi Tom,I,ve just read Andy Elisons article on prop selection, a really good and explicit explanation of what does what and why, but the tabels mentioned in the article seem to be missing.It would be great if you could include these.
    Keep up the good work the sight is looking good, and if this is just the beginning then you're on a winner.
