RFguy Posted July 14, 2021 Share Posted July 14, 2021 (edited) Really very sophisticated constructed cover. excellent value for money , nice sail cloth stuff with felt liner. fits well, no slop and no fluttering in the wind. Additional velcro seams for attachment to full all over cover. photos. (not sure if I have the ties around the struts right, I think I need to extend the straps (variable) full length and go around the leg.) I put it on for the first time in the near dark.

mkennard Posted July 14, 2021 Share Posted July 14, 2021 That's a different setup than mine. Mine covers the cowling and the bottom half. I can't find a photo with mine on. Link to comment Share on other sites More sharing options...
Roscoe Posted July 14, 2021 Share Posted July 14, 2021 Yes I have a friend who has a 160 and his Punkin Head Cover runs right up to and under the prop and also goes right down under the doors. Cant get out to take a pic due lockdown. Link to comment Share on other sites More sharing options...
mkennard Posted July 14, 2021 Share Posted July 14, 2021 Same, my first job when I'm allowed out is to drain the tanks. Link to comment Share on other sites More sharing options...
RFguy Posted July 14, 2021 Author Share Posted July 14, 2021 These ones are Weathermax fabric, better for shrink than the Sunbrella material (am told). And the velcro doesnt get attached to the lining. It's nice kit. Link to comment Share on other sites More sharing options...
Guy s Posted July 15, 2021 Share Posted July 15, 2021 This is my Punkin cover which I purchase 5yrs ago when I finish build the Sav, I absolutely luv it and it's packs down well and it's very light and carry it in my travels. I even keep it on in the hangar at home as it keeps the dust off the windscreen. Also thought I'd would add a extra photo of the Canberra Bomber on it's second flight after 11yrs rest and restoration just after we landed at Temora recently which was pretty cool... 1 Link to comment Share on other sites More sharing options...
FlyingVizsla Posted July 15, 2021 Share Posted July 15, 2021 Our Punkin Head cover taken Feb 2008. The covers on the wings were made by an upholsterer. 2021 and they are brown with all the dust & muck in the hangar, but the Punkin Head cover is still looking good and clean. Highly recommended. This was the honeymoon - we spent it in the hangar. 1 Link to comment Share on other sites More sharing options...
kiwiaviator Posted July 17, 2021 Share Posted July 17, 2021 I have the same one on my 230 Glen. Great covers and yes, I have the side straps around the main spring. Link to comment Share on other sites More sharing options...
RFguy Posted July 18, 2021 Author Share Posted July 18, 2021 (edited) Got the straps right now... image before prop and cowling covered. Repegged after the winds and rain of last few days. despite the glum wx, got 0.8 in yesterday. fixed a CHT sensor. This material is reasonably heavy/stiff compared to some I've felt. Wont flap in the wind. Will move under cover before too long. Was in hangar until April. Sun/temp is not too strong down here this time of year.

Hey, what's the basic empty weight and empty arm of your J230? I'm writing a loading chart application and want some samples. Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 WB.xlsx the values in cells T1 on the Sheet 1 workbook are my aircraft airframe J766 other aircraft in there may or may not be right depending on what scenarios I was looking at. 1 Link to comment Share on other sites More sharing options...
Tasmag Posted August 23, 2021 Share Posted August 23, 2021 RFguy, shouldn't the front seats be a negative figure on the 230D, and aren't the wing tanks only 65L (But they may take more I suppose)? Mike Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 230D seats are fore of the datum. wing is behind the seat. wing tanks 135 L + 5L header Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 (edited) that's why it is the king of LSA. but you need to wear a hat to stop sunburn because the wing isnt over your head. Edited August 23, 2021 by RFguy Link to comment Share on other sites More sharing options...
Tasmag Posted August 23, 2021 Share Posted August 23, 2021 The front seats should be -12 in your spreadsheet I think, it is the only station in front of the datum. I think what confused me was the addition of a header tank and the same fuel listed in the wing tank calculations. 135l in wings and 5l in header. Normally the aircraft is weighed with header fuel and not included in the weight and balance because it is considered unusable fuel.

RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 (edited) actually that's not my aircraft in that spreadsheet you are right about the - and + on the 12mm. and yeah the header I see is weighed in at weighing. and also some fuel..... my aircraft is : from the book : datum is right hand leading edge. empty arm is 151mm aft (-) of datum +12mm for front seats. Headset holder is -12mm (aft of datum) as for the header tank, you are right- my plane is 367.5 empty +2kg unusable fuel in the wings @ -451 +3kg in the header@ -1520 +1kg headsets @ -12 +ventral fin ballast 1.3kg at -4080 Edited August 23, 2021 by RFguy Link to comment Share on other sites More sharing options...
Tasmag Posted August 23, 2021 Share Posted August 23, 2021 RFguy, Out of interest is the ventral ballast inside the ventral fin is a lead shot/resin mix. I've been trying to work through a removable 5kg ballast system that doesn't rely on the ventral fin attachments. Mike Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 Hi Mike I have updated my spreadsheet without the header tank (as it is in the original weighing I see in my POH) . note for others- this is a bit of an experimental worksheet, there are a few what if scenarios in there .... be sure to put your own numbers in.. Note mIke I have the tendency to use - for fore and + for aft. Of course does not matter which way you do it, as long as you are consistent !

RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 yeah I only have 1.4kg but other some aircraft have alot more. J170Cs got an extra few kg up from with the upgrade they got that was that large ventral fin you know they got in the 2011 upgrade do you have 5kg back there ? what plane precisely ?

Tasmag Posted August 23, 2021 Share Posted August 23, 2021 RFguy, Don't currently have any ballast, but 5kg would be handy with some loadings. (Jabiru 430). Mike Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 (edited) Hi Mike oh the configuration of two up and low fuel and nothing in the back means you trim full back once the flaps go out and then need pretty much full travel on the pitch to get the flare high enough as the horn sounds ? glen Edited August 23, 2021 by RFguy Link to comment Share on other sites More sharing options...
Jabiru7252 Posted August 23, 2021 Share Posted August 23, 2021 He's a quicky spreadsheet I knocked up while dinner was cooking. Probably needs work and the empty arm is a guess. When I'm at the club next I'll get the correct numbers for the J230C we have. Incorrect loading and you get a warning.

Tasmag Posted August 23, 2021 Share Posted August 23, 2021 RFguy, Always make sure I am inside the envelope by adding water containers in the baggage area as needed. Never had an issue with trim when inside the envelope. Mike Link to comment Share on other sites More sharing options...
RFguy Posted August 23, 2021 Author Share Posted August 23, 2021 Yeah I am well inside the book CG envelope with the 2 up and low fuel but it takes alot of pitch input to get that nose up at flare-stall with idle power... agree the water would make life easier. When I am flying myself, 1 up, I never notice any issue. With two up, nil baggage and 50% fuel, %MAC is 13.6%. (fore limit is 10%) and I reckon you'd want to be a bit careful in hot weather, carry a little more speed into the flare to get the nose up enough. At 1 up, %MAC is 15.8% and getting the nose up is easy. That 2% makes quite a difference. Moving the 6kg battery to behind the front seats would make a couple of % of difference, also.
