The topic is linear actuator for a cowl flap. Suggesting that there are other ways to actuate a cowl flap is not really off topic.

There was an interesting cowl flap shown somewhere here, French bloke had it on top of his cowl to release heat while on the ground. From memory it was hinged forward of the midpoint of the flap and lightly sprung, so at low speeds it would open but any wind pressure would close it.

Wasn't a bad watch if you're prepared to gloss over the obvious errors. Gerard is usually pretty good for a bit of entertaining violence.

More clickbait. Having a "bumper attached to the rear of the plane's fuselage scrape along the runway during takeoff" 4 years ago, would in no way would contribute to the recent disaster.

Video on the ABC link provided above. Click on "show more posts". Nose seemed to be reasonably high all the way down the runway. Wonder if that contributed to it going so far.

Can't be RAA, it's a multi-reindeer craft

Found the bugger!

Unless I'm mistaken, you're not allowed to have passengers during the 25 hours proving thing anyway, are you? Which removes the possibility of paying for your passenger's therapy for the rest of their life. Therefore wouldn't (in most circumstances) the $10m public liability through your membership be sufficient? Of course there's the hull, but that's up to you. In my case I'll probably take the risk without hull insurance, because as a scratch built aircraft it only owes me about $25k over the 14 long years it's taken to build it (so far).

To whoever buys it... let's talk hangarage 😁

Thanks Bob. I'll have to check the vent, not sure if mine has one on the header tank or not.

Actually don't have a fuel gauge. Tempted to try those sensors that stick on the outside of the tank and have an LED when there's no liquid at that level. Until then, it's a matter of calculation and of course the low fuel indicator when the header tank is the only fuel left (15 minute warning).

Help needed! I'm at the point of testing the fuel system. It'd be great to get some advice about how to go about this. These are my thoughts so far: (note - all filling of tank and back to containers through Mr Funnel to remove any contaminants) Test 1: From tanks to splitter Visual inspection of all fuel lines from tanks to carbs. Check of all quick release fittings to ensure engaged and open. Check tanks to ensure no debris/insects/whatever. Prepare aircraft (tyres to correct pressure, sitting level, towels on wing roots just in case of spill). L + R fuel taps off. Put an initial small amount (5 litres?) in each tank and check for any leaks from tanks to fuel taps. Cockpit fuel tap off. Turn L + R taps on and go under plane to check header tank fills correctly. Check for any leaks from header to cockpit tap. Disconnect line that runs from Rotax mechanical pump to the 5-way splitter. Put the end in a new bucket with litre graduation marks. Turn cockpit fuel tap on. Check that fuel drains with no leaks into the bucket and time it to get flow rate. Test 2: To carb ends As above, plus: Increase amount of fuel to say 10L per tank (beware of bucket capacity while draining) Connect line back to the splitter but disconnect the carb ends; drain to 2 buckets Check for any leaks in the system - including in cockpit (line to fuel pressure gauge) Test 3: Electric pump Put 10L in each tank and open all taps. Test the electric fuel pump - measure flow to the buckets. Check that fuel is being delivered evenly to each carb end. Test 4: Fuel pressure gauge Reconnect carbs. Put 10L in each tank and open all taps. Check that the fuel pressure gauge on the panel is registering pressure. Test 5: Full tanks Top tanks to full (without spilling) Check for leaks throughout entire system Check fuel pressure gauge Drain from header drain (lowest point in system) to fully drain. Any thoughts? What am I missing? Is the testing order right? Are there other tests I need to do? Is the full tank test really necessary? (Just thinking - that's 77 litres of petrol, and both our cars are diesel...) All assistance gratefully received. Cheers, Marty

They're finished Taylor Monoplanes up there having fun, just waiting for you to join them! Have a good xmas Don.

Looks very short. Wonder if it was twitchy in pitch.
