I spent a bit of time with these guys this morning. Shark Testing.mp4 Andrew was testing the operation of the landing gear. It was interesting to see the setup. The nosewheel is steerable but even if you have the rudder turned at the time the nosewheel straightens itself out before it enters its little hole.

Perhaps one to pass around forum members 😁 I told Mrs M it's always nice an quiet here at the airport after the sun goes down but the Singapore guys are training at night. Hopefully they'll give up soon because it's nearly 9:45pm and I need my beauty sleep.

Keep an eye out for this aircraft. I'm checking it out at 9:00am tomorrow at Jandakot. I was here this afternoon when it went for a test flight after assembly but I didn't know it was here until after lockup. I don't know if I'll get my bum inside but I can only hope 🤞 Apparently it'll be touring the country for promotion so if you have a spare $400k tucked under the mattress it might be a good time to pull it out. 150kts cruise with a 912ULS and retractable landing gear.

There are only a few airstrips en route and I don’t know that any have fuel. Two of them are in military training space so can only operate on weekends. There would plenty of private unmanned or abandoned airstrips, enough to stop off and refuel with onboard fuel. If I add extra fuel later on I will most likely have a transfer pump so that it can be added inflight. I’ve just been looking at another Sportstar that I attempted to buy last year. It has twice the fuel in wing tanks but the owner has gone to ground, uncommunicative. It’s also been out of registration for several years but is an LSA so different rules apply when reviving it.

I wish I could confirm everything you say skippy but it's a bit difficult to calculate while the plane is sitting in my backyard and I'm sitting in a no-stopping zone in Perth. I took the opportunity to change a LF wheel while I was here because I had to be broken down or have Mrs M walk a very long way to the hospital. I have to slip off my Clark Kent jacket every time I change one of these wheels because they weigh as much as I do.
-
I have an inflight adjustable propeller that might give it an edge?
-
Yes I realise the limits that’s why I’m talking extra fuel. I’ll know more after I get registered and in the air.
-
Skippydiesel has posted a lot of details on radiator hoses. I just Googled the automotive sites for mine and got every hose to fit without changing the bend.
-
Not going to be approved but if I mount a few low enough it could expand my options on where to land 🤪

Similar colours, might have been a husband and wife spat 😃

I'm not even flying yet but I expect to have a lot of trips Cue to Perth and back. My plan is to see if I can become a member of the Northam Aero Club and use that as my southern base. It's 261.9 nautical miles each way and an hours drive to Perth. Yesterday we left Cue at 4:20pm and arrived here in Bindoon at 11:38pm stopping for about half an hour at Paynes Find for a bite to eat. We are still an hour from Perth. If my plan works out I'll have a little Mercedes van with a bed and basic extras parked at Northam for the travel to Perth. I bought the van to travel around the country a few years back. If that works out my van will be available to known visitors dropping in.

There are not a lot of service stations where you can park your plane in the driveway. Do you have a strategy for moving those 60L to the airstrip during your cross country travels?
-
How I love acronyms This is the first time I’ve heard of Zero Fuel Weight. Yes of course these weights a balances apply but it appears to me that the written data supplied with the plane gives some latitude for alterations to be made while still staying within legal limits. As I stated earlier this plane is going to registration unmodified however if I need more fuel to cover the cover the long distances between airports out here it looks like the option might be there to add it. The same plane, same fuselage, engine and control surfaces is carrying twice the fuel in later models however the MTOW is up from 550kg to 600kg.
-
Yes that’s true however in the service manual for this particular aircraft it gives me instructions to reweigh the plane after any additional weight or accessories are fitted. Then it says I should reprint and fix a new W&B placard. From my point of view it’s saying, go ahead and do it but do it right.
-
Maybe but why mention adding fuel to a larger tank if that option doesn't exist?
-
That was just added to get a reaction after the suggestion of moving the Datum to an invisible position forward of the spinner 🤣
-
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.
-
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.
