Hi, Can anyone tell me the approx. lift off speed of a supa pup, say with 80kg pilot, 20kg fuel, 4cyl 4 stroke KFM motor, on a 10 degree still winters morning, say altitude 1000ft ASL. Assuming tail lifted & elevators level. I intend doing some ground runs soon & this is good info to have. I believe that stall speed is around 38 knots?? Is it a hard stall in this plane?

SupaPup

Gday Rusty, I’ve got 220 hrs now on my Pup MK4 with Jab 85 hp- cruise 90 knt @ 2650- stall 42 clean- 40 1/2 flap- 38 full flap. Could never get on top of my oil cooling until I modified the air intake over the oil cooler now it’s fine, how do you attach a pic to this chat? when I can get it to work I’ll send one through. Steve.

Sounds just about perfect temps (80 - 90 deg C) to me. You need those temps to remove any water that's condensed into the oil when it cools after running. They are the sort of temps my Jab 160 / 2200 oil runs at, and I wouldn't want them any lower than yours.

If you post in this thread you'll attract those that went there beforeAero Pup Cooling ?

OOPS posted in the wrong spot, please have a look at general discussion if you have any ideas on oil temps on Jab powered Supapups or Aeropups, thanks Steve .

Hi Folks just wondering if anyone that has a Supapup or Aeropup with the 2200 Jab could give me an idea of what oil temps they are running? I have the standard Supapup cowl with the oil cooler on the front of the sump behind the front air intake as per the plans but am having trouble keeping the oil temp below 80deg in cruise & 90 in climb sometimes higher .Have tried playing with the duct but am not having a lot of luck getting it any lower unless the outside air temp is low, admittedly the ambient has been around 25 to 30 lately in SA but my old SK Jab never run much over about 60deg no matter what it was doing outside. Anyhow any feedback would be appreciated , thanks Steve.

Gday Brett well clocked 2hrs yesterday and 1hr today and very happy with the performance , climb out @ 65 gives 1000 fpm, 2600 rpm gives 80 knt, 2700 gives 85 & 2800 gives 90. Not sure about fuel burn yet but all gauges stayed in the first 1/3 of the green, did a heap of stalls all in all very happy.

That's great :) It should go really well.

Give us a call when you reach 2,000ft on your first flight.....just a loud Yeehah!! will do as I shall probably hear you from my house north of Adelaide. Alan.

Morning Brett & Merry Xmas, yes interesting question she comes in at 249 kg empty. Not sure where the weight is but that seems heavy to me, I just sold an SKJab and that was only 259 empty so I guess I'll be losing some weight. It's plackarded 340 MAUW but I believe they were increased to 380???

Thanks Brett was that a Jab powered unit?

Yeah thanks Nev (it was auto correct by the way) Yes they seem to be a solid little aircraft , not sure how many of the MK1V's are around (4 VH registered in NSW I believe ). It appears the only difference between the MK1V and the MK4 ( which are the same value of course, why you wouldn't call it a MK5 Nowbody knows) is I think a folding wing and a little bit less span I have been told, maybe Alan may know? being an ex SupaPup owner.

Steve.

Thanks Alan and yes won't attempt to fly the "SuperPub" never was fond of auto correct. Used to own a Fisher Koala, much slower (55knt) with a lot more lift and totally different wing profile, docile wonderful little plane.( until you flew somewhere and the wind came up) But have 3 aircraft with nose wheels since then that all fly different, will probably give this one a go next wk after doing the W&B at the local airfield , this one has the Jab motor so I'll give it a good looking over prior to flight. Fortunately it's the solid lifter as was my last so very basic.

Gday have just purchased a SupaPub with Jab 80 hp but have not yet flown it (flap model 1V). I have owned a tail dragged before and have flown several others over time but was just wondering if anyone has any time in one of these? Would like any feed back as to their characteristics.

Thanks

Steve.
