Bob Cotsford Posted October 19, 2013 Share Posted October 19, 2013 Thanks Tim, £4 or so saved I'm hoping to stock up at Cosford next week, so I'll just grab a few 1/4, 3/16 and 1/8 sheets to put aside for a PC (never thought I'd be building anything remotely PC but there you go).

Colin Leighfield Posted October 19, 2013 Share Posted October 19, 2013 Bob, at risk of admitting how dim I am, what's on at Cosford? Quote Link to comment Share on other sites More sharing options...
IanR Posted October 19, 2013 Share Posted October 19, 2013 Having read that the Pushy Cat handles high winds very well I'm very tempted. However, I really don't like the high pitched screaming sound of some of the pusher prop jet types I've heard. Is the Pushy Cat very noisy?

John Privett Posted October 20, 2013 Share Posted October 20, 2013 Well, it's been a while since I last flew mine, but I certainly don't remember it being particularly noisy. Most of the noisy ones you're probably thinking of - like the Zagi - have the prop immediately behind the trailing edge of the wing and that seems to be the cause of much of the noise. You'll see the PC has the prop well back from the wing. Quote Link to comment Share on other sites More sharing options...
GrahamC Posted October 20, 2013 Author Share Posted October 20, 2013 Mine wasn't too noisy... Nothing compared with resonating depron! And yes it is astonishing on a gusty day when nothing else will fly. Quote Link to comment Share on other sites More sharing options...
IanR Posted October 20, 2013 Share Posted October 20, 2013 Good that's settled then. Pushy Cat it is. Thanks for the reply lads. Quote Link to comment Share on other sites More sharing options...
IanR Posted October 20, 2013 Share Posted October 20, 2013 Tim, if you're going to buy a new RX and you're thinking of fitting a gyro, take a look at this special offer from Hobbyking - £9.89 for a combined RX/Gyro. I'm thinking it might save some space in a relatively small fuselage. **LINK** Ian PS I hope you've still got your Red Bull markings available. Your Pushy Cat looks the business.

Tim C Posted October 20, 2013 Share Posted October 20, 2013 Ian, Must say the Orange RX/GRYO unit is good value, but I already have a 401B Gyro, designed for a Heli but can be adapted for Aero on any axis, so I will be experimenting with this. Red Bull schemes always available Quote Link to comment Share on other sites More sharing options...

IanR Posted October 20, 2013 Share Posted October 20, 2013 Thanks Tim and Ken. Have downloaded/printed the original build article and plan now ordered. Lovely jubbly! Off to read that 60+ page thread in the "other place". Ian Edited By IanR on 20/10/2013 12:24:06 Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted October 20, 2013 Share Posted October 20, 2013 Pushy Cat builders, I have made a quick drawing of the formers for the fuselage, the PDF file is located HERE , it is at the top of my blog page just under the photograph of the three models. If anyone would mind printing out and checking that the dimensions are correct that would be great as at the moment I have no printer ink!

IanR Posted October 20, 2013 Share Posted October 20, 2013 Richard, on my printer the left hand side of your drawing doesn't get printed - its too close to the edge of the paper - so the left hand side of your 100mm scale is missing. I rotated the drawing by 180 degs and now the right hand edge of the lower fuselage doubler is missing from the drawing. But now the 100mm scale is in full view - though according to my ruler and printer its (at a guess, about) 0.2 mm too short. Quote Link to comment Share on other sites More sharing options...

IanR Posted October 20, 2013 Share Posted October 20, 2013 Bob, when printing a pdf my print dialogue gives the choice of 1) Fit 2) Actual size or 3) Shrink oversized pages. I chose Actual size which printed near as dammit but then, of course, the drawing didn't quite fit on the paper. Quote Link to comment Share on other sites More sharing options...
John Privett Posted October 20, 2013 Share Posted October 20, 2013 Bob, as Ian said, you get a choice of 'scaling to fit' or 'actual size' when printing - I nearly missed it! Printed "actual size" on my HP Officejet 6500A Plus it prints the entire page OK, and the 100mm scale is only fractionally out - unlike Ian, on my printer it's a fraction of a mm too long. But that's still a lot more accurate than my cutting/building! (And anyway, my PushyCat is already built, it just needs re-building. Again...)

Richard Harris Posted October 20, 2013 Share Posted October 20, 2013 Try this, To have it print correct select print from the PDF reader and look in the Page Handling section. Make sure the Page scaling part says either 100% or None and auto rotate/centre is not ticked. After making sure this is correct use printer settings to make sure print orientation is correct and it will print out at correct size.

John Privett Posted October 20, 2013 Share Posted October 20, 2013 One other "gotcha" I recently discovered with printers (well, mine anyway!) is that if I select the "automatic double sided" print option then the printer very kindly - and without mentioning it - shrinks the print size slightly... Apparently it's so that the paper-handling mechanism to switch the paper round doesn't smudge what's just been printed. That had me tearing my hair out trying to work out why labels that previously printed out ok were misaligned as you went down and across the page, and all because I'd recently made double-sided printing the default. D'Oh! Quote Link to comment Share on other sites More sharing options...
Erfolg Posted October 20, 2013 Share Posted October 20, 2013 I have read through all the posts. I now have my Pushy Cat drawing, read your comments with respect to high flying speed. After some consideration, it is my intention to go the NACA 0010 route, as per the link. I am torn between a Depron glass clothed wing or a built up wing. I am looking for a lower minimum speed, whilst willing to sacrifice ultimate speed. Rather than use a single servo with torque rods, in the wing, I intended at the present to use two 5g servos. With top linkages as advised for a foam AT 6 by some unrecorded hero on this site, as it really does save servos. I am not sure why I need RH plots, although for me they have not come out with the 100mm being 100mm, I will try again. as I cannot find the file for the PDF window. I will probably go for the HK 2825, although I have an innrunner that may be suitable. There are a number of questions. Do the fins benefit from tow in, as it complicates the build to incorporate. Is there any benefit at all from the built up fins as per the link? Mainly because the material saved is little, and this could be replaced by the weight of the glue that would be needed? The RH canard really looks the dogs dangly bits. When will this be published. Many years ago I built a slope soarer, a canard called the Enigma that looked a little similar. It used a rolled ply fuz, if any one remembers it. The RH canard looks better, I am guessing a lot smaller than the approx 60" span Edited By Erfolg on 20/10/2013 21:40:30 Quote Link to comment Share on other sites More sharing options...
GrahamC Posted October 20, 2013 Author Share Posted October 20, 2013 Erfolg. Mine tracked really well and didn't have any conscious toe in. You could certainly bias the sanding of the fins if you wanted to create a slight effect. Quote Link to comment Share on other sites More sharing options...
