    Interpret this as you wish. I take this as allowing me to install a larger tank as long as I alter the load W&B label as instructed elsewhere in the manual.

    I'm confident I have it right. The empty plane bit has an ARM back from the leading edge. The weight at that point is the entire weight of the empty plane with 2.9L of unusable fuel. ARM x Weight = Moment. Total moments / total weight gives the CG. Empty weight determination The empty weight of an aircraft includes all operating equipment that has a fixed location and is actually installed in the airplane. It includes the weight of the painted airplane, accumulator, standard and optional equipment, full engine coolant, hydraulic fluid, brake fluid, oil and unusable fuel 2.9 l. The aircraft is weighed without crew, fuel and baggage. Anyway if you guys are calculating W&B before each flight then your opinion is more important to me than the expert (ex is a hasbeen and spurt is a drip under pressure) who learned it from a book.

    That sounds good however I first had to understand the process and method of calculation. I'll have a test coming up and to pass that I'll have to do it manually.

    It might look confusing as the results don't end up as a reference on a chart. They didn't supply a chart in this operators manual but use a % of Mean Aerodynamic Chord (MAC) as the load limits. I've got my head around it now and I'm happy with the results however I'm sure my trainer will set me straight when I get back there.

    Coolant in that bottle doesn't get to circulate or play any part in cooling the engine. It's just there to handle expansion and some may return to the cooling system as the engine cools.
  6. Moneybox
    I think Skippy could be right. The bottle has plenty of room for expansion. If you go with the suggestion of a neat fitting washer and a nut inside seal it with an o-ring so that it doesn't need to be tightened. Most plastic won't take compression very well without fracturing. If I was doing it, but I won't, I'd go with Thruster's suggestion only I'd insert the hose through the side of the bottle not the top. That way it would not come near the cowl and would never have to be disturbed. Use a soft rubber hose rather than a clear plastic.

    Most likely the same in a later model just for the bigger tanks giving it it a longer range. I train in an Evektor Harmony so I feel comfortable there.

    Yes I have a wife too so not the plane I'd have chosen 😀 I didn't actually buy it, I acquired it through a family member who purchased it new (demo model) but never learned to fly. Beggars can't be choosers. I need to cover longer distances and carry more load but as I say it was not a planned purchase.

    Thank you. Mine is an early model, 2004 with a single tank in the fuselage. The later planes have wing tanks that alter the CG amongst other things. I have been confused by the documents sent by Evektor. I've had to request original documents for the plane as most have gone missing. I have documents dated the same with the correct rego number and serial number but some are in metric and some imperial. Unfortunately I paid to have the Aircraft Operating Instructions printed and wire bound in A5 but the data is incorrect. I'll have to go again. Those instructions are dated 2006, with dual wing tanks and incorrect W&B for my model. Reviving an old plane comes with its challenges.

    The Sportstar has a reputation of a beautifully balanced plane to fly. Best not tampered with until the day I choose to pack a few more litres of fuel under the seat. At this point it has no modifications since new.
  11. Moneybox
    Anyway I've achieved my goal. I have some understanding of weight and balance and how to calculate it. Perhaps somebody might get some value out of modifying my excel file to suit their own.
  12. Moneybox
    From a calculation point of view the excel file makes it easy to enter a negative if needed and the Datum remains the same.
  13. Moneybox
    I might have to have a little rail running forward with a weight adjusted to suit the occasion. I've got some of this lying around somewhere.
  14. Moneybox
    HaHa, yes a typo. Grams if you like or 0.74kg. As stated the datum is the leading edge of the wing. I've entered ARM measurements from that point rearward. The positioning of the wheels is only relevant when calculating the CG of the empty plane. I don't think it has anything to do with my loading of Crew, Fuel and Baggage.
  15. Moneybox
    The Datum is the leading edge of the wing. The fuel tank arm is 920mm and the baggage is 1270mm (in line with the wing trailing edge) and is just big enough for that pair of electric scooters that we're going to need to make it from the airport into town 🤣 The fuel tank is wedged in between the seats and the luggage space.
  16. Moneybox
    Yes I understand that but if I remove the fuel it's still well within the % MAC. That file is interactive so you can easily see the effect when altering various weights.
  17. Moneybox
    I'm grounded for now so I've been doing a bit of study but I got stuck on Weight and Balance because I find some of the references quite confusing. Anyway to get it clear in my mind I entered the data into Excel because at least I understand what I'm looking at. Weight and Balance 24-4149.xlsx Can one of you smart cookies, of which there a few, please confirm that my calculations look correct. My plane has an empty weight of 309.8kg at 233.21mm aft of Datum. I have one 65L tank and the crew weight 119kg. It looks like there's room to expand on the fuel or luggage if I get the balance right?

    91 740 is for IMC. Single-engine aeroplane – VFR flights by day – engine not to be shut down (91.735) You may only shut down an engine during a day VFR flight if the flight is for pilot training and you hold a flight instructor rating, an examiner rating, or other authorisation. Only flight crew members may be carried, and the aeroplane must remain within gliding distance of a safe forced landing area. CASA EX67/24 (30) allows observers on flight test and proficiency check flights who are not flight crew members subject to the conditions set out in Appendix D. For training purposes an engine shutdown should be simulated. An engine should not actually be shut down in-flight for other than a type specific training requirement such as an in-flight air start. Nothing prevents you from shutting down an engine in an emergency.

    I intend to upgrade my transponder to ADSB in/out along with a few other things but I want to see this plane registered first.

    The application I did for a Class 2 asked for my medical history. My trainer said I should have just ticked No,No,No, right down the list an it would have gone straight through but imagine what would happen if you made an insurance claim and they found you'd had an undeclared medical episode years before.

    For jobs like this we'd just supply a CAD drawing of the entire dash and the engraver would cut the holes as well.
  22. Moneybox
    I guess the days of engraving have gone. We used to use an engraver in Balcatta WA. The machine just followed whatever image/text we supplied but worked like a milling machine and mechanically cut it out. For jobs like this they used a triplex plastic where they cut through the top layer exposing the text colour layer underneath. No paint or anything else.
  23. Moneybox
    There must have been a connection there somewhere? Perhaps in the process of going for a medical, some will go nuts and others choose to bolt.
  24. Moneybox
    That sounds like their speed of travel.

    Anything you alter could upset your structural warranty and even a potential insurance payout.
