One of the coolest car engine blocks would have to be the Lamborghini Miura. It was built like a motorbike engine- engine block, gearbox and diff cast in one piece.

Still, testing to destruction would glean a while bunch of info above individual calculations. For instance, say calculations tell you part A might break. Actually running a prototype until part A breaks might show that breaking that impacts parts B and C.

This is what went through my head when he said it. But those are rockers pushing on the valve stems. I haven't looked at the Merlin, whether it has overhead cams driving rockers or cams on valves. Unlimited hydroplanes used Merlin's and Packard's until the 1970s as well. Would be interesting to see what they did to boost performance. Miss Bardahl for instance ran at 3000 hp 😲

Wouldn't be surprised if some of those racing guys have made roller followers or equivalent for their engines

There are some newly manufactured parts. If you look at the link I posted, you'll see that pistons, rings and even three differently profiled camshafts are being manufactured. But clearly not fuel pumps as per my original post 😄

Totally agree..like I say, you can't get much breezier than an X mount on a gymbal 😇

I guess what I'm saying is that with the gimbal mount, if you are on a track where the sun is beating down on the screen, you can tilt it a few degrees down until the sun or your track has moved. It's all academic for me of course, test flying means there's no point even using a tablet. And when I'm done, I still haven't done my navs anyway 😄

There's heaps of options. I'm mostly referring to the gymbal part. What I have attached to that is the X type cradle that just grips the tablet on the sides. Virtually every part is getting free air flow.

I like the Ram ball joint mount because you can angle it how you want and if outside light changes (sun glare etc) you can just retilt it to suit the moment. Also if a passenger is helping they can tilt it towards them if they need

Dunno. You can't edit anything here after 15 minutes, so that could be tricky

Got it.

This is the list so far, rather scatologically ordered, for my Bushcat. But there are many Rotax options listed: Suppliers: Loravia.com - Rotax engine parts, France Individual parts: Radiator cap is BMW P/N 17112345074 at about 1/2 of the Rotax price (fitted to BMW motorcycle F650 with Rotax engine)."

When I first started the thread, it was just to say to folk it's a good idea to compile a spare parts list for their aircraft. But of course many of us are running Rotax so those parts will be common to many aircraft. I think the only way would be to trawl through not just this thread but many sources and compile a list. The problem being of course there will always be new sources. Talking of Rotax parts, was it you that was using the Vauxhall/Opel fuel pump? If so, how's it going so far?

Yeah, it was fixed pretty quickly and flying again 🙂

Pretty sure that goes for any aircraft

So funny I wrote this next, indeed, the kit manufacturer did end up going broke 😄

Great idea, although straying quite far from the original intent of my thread. I might buy some of those, I'm.curious about the difference in temps between the two modules, since I imagine the top one gets more cooling airflow

Possibly because he extended his gliding range 😉

Already flying again. His reasoning for not lowering the landing gear was sound. A reminder that people die trying to save the aircraft.

True. But it does give you a feel for what's happening inside these sorts of devices. The same principle applies - you get what you pay for. I believe though the main problem you could have with 12v to 5v switch mode is a dirty voltage. Which was probably covered in this thread. So a risk of interference, but a much lower risk of killing your device if the charger is cheap and nasty. I was so anxious about interference I bought a linear supply kit to put in my plane. I didn't end up using it. I mean, the se2 runs a lot longer than you can fly. I'm just using the battery. No daggy cables hanging around either 🙂 Edit, I see you are looking at other devices. Always aim for a higher charge current than you require. If the charger is ok, but not brilliant and you are cutting it close to the bone then you are more likely to have voltage sag etc, which you can see the effects in that article I posted. USB is a funny world, there seems to be limits I guess due to wire size in the cable. If I could, if I have a 2 amp device I'd want a charger that can do double that to be sure. In any case, the higher the better. One of the advantages of switch mode is that if it's not putting out much, it's not creating much excess heat in proportion. For instance, If you've gone nuts and somehow found a good quality 10 amp USB charger (I don't know that there's such a thing) then it won't be using much more energy than a 2.4amp charger if charging the same device. I imagine in fact this 10 amp charger will likely have a longer life because proportionally it's not working as hard. If it's a linear charger then yes it's just turning excess voltage into heat. Smooth and stable output, but hot and wasteful. I love them ☺️

Haven't read all of this thread, and maybe I've actually posted this before on THIS thread but when there were some doubts about charging of the SE2, I just emailed them and got the info from the horses mouth. In essence they said just use any quality charger, they made it seem a little more critical than it is to discourage people using $2 temu crap and blowing up the device. I usually use the charger from my lenovo tablet, This article should serve as a great eye opener to why you shouldn't fool yourself into thinking that somehow your $2 piece of shit is from the same factory as a properly made charger just because it LOOKS the same: https://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html Incidentally, on the strength of this article I bought a HP touch pad charger to use for my C64.

I guess we'll see more of this in the future https://www.bbc.com/news/articles/cn5qk4de997o#amp_tf=From %1%24s&aoh=17582735976570&csi=0&referrer=https%3A%2F%2Fwww.google.com&ampshare=https%3A%2F%2Fwww.bbc.com%2Fnews%2Farticles%2Fcn5qk4de997o
