    On the subject of that video, I'm a bad one for not wearing gloves. Never used to, even washed parts in petrol as an apprentice. It's a bad habit now that I know better. I figure it's safer than smoking though 😊

    What are you talking about? People have never lived longer than they do today. Even in 3rd world countries. And people died of all the things we imagine are modern, just that no one had described it yet. Go back 150 years, and if you died of something unknown, there just called it epilepsy and moved on. But it was probably lung cancer, or lead poisoning, or leukaemia or even just a small infected wound that no one noticed. Go back 1000 years and Europeans didn't even name their children until they were about five because they were probably going to die anyway. I feel the most massive thread drift coming on 😄

    I never heard of such a thing until I started building my plane. The video is from a race car mechanic so I guess popular in those circles, as well as aircraft.

    I didn't notice what one he had to be honest. The one I ordered has a circular blade

    My second question is answered on the FAQ 😄 Q: Will the ACS oil can cutter cut Rotax filters? Yes, it will cut Rotax oil filters.

    Is this one ok? I anticipate using it once a year. And I assume it will work on a Rotax 912 filter? I don't have a filter onhand but from memory the Rotax is less than 5" https://www.aircraftspruce.com.au/catalog/topages/acsoilcancutter.php#

    I have no idea what this means. However, the saying "A night with Venus, a lifetime with Mercury" comes to mind 🙂

    Better than brass 🙂

    True. I personally wouldn't be comfortable with aluminium cabling. Mainly where lugs are connected to the cable. As per the other thread, I think we both agree there's a lot of chance of electrolysis if moist. Then again, I vaguely recall the Piper warrior having aluminium cable, and I haven't heard of problems with it. On aluminium cabling, my American friends tell me it was popular in housing years ago, and still a big cause of house fires.

    So when I built my plane I used a dipole because it was neat and I didn't have to put a hole in my fuselage. But the radio hasn't been great. In desperation I ended up putting a hole in the fuselage anyway to make the dipole more upright. So two questions I guess. Would a regular aerial normally work better than a dipole? And what area do I make the ground plane?

    When I was a first year apprentice I went out with a 3rd year apprentice to fit some cabling to an aluminium hulled boat. He used brass bolts! I probably wouldn't have known better. The owner did and made us come out and replace them all with stainless steel. I got curious and at home I made a battery from some scrap Ali and copper coins with salt water for the electrolyte. From memory each cell produced 0.5 volts, which is pretty significant. Those junctions would have corroded in no time 😲

    Totally agree and I see this on Zenith 701s. The only drawback is you have to add more weight in the form of thicker and longer battery cable. But better that than just adding lead or something useless.

    Can't we all just be friends? 😇

    You need to be on the paperwork as a builder..not sure if someone is going to put you on there just because you handed them a spanner. As well, since in reality your friend built it, if he royally screwed up and it crashes, although really you didn't have anything to do with it, now you are legally liable.

    Love it! A story to tell 😊 In my case I thought I knew everything about aircraft. I didn't. I didn't understand that in most regular aircraft, the elevator needs to produce a little bit of negative lift in level flight. I actually added a positive angle on it. Just that one thing probably cost me several metres at least, and probably first prize. I came third. The flight itself was a total blackout for me, didn't remember it at all! Basically one moment on standing on the edge. The next I'm swimming to shore. Probably doesn't help that I'm not good with heights 😄

    I can smell the ether just looking at it 😊

    Man, just chuck a four barrel on it and wear the slight reduction in power 😊 On a serious note, I'm not quite getting what happened with the computer. Do those tuning sensors run though the computer? Or is it a typo and they meant to say those sensors were on the same circuit as the computer? Whatever the computer normally draws, it would still be drawing so I'm not quite following. And yes, WTactualF regarding taking off anyway. They were testing for power. But why bother if you're just going to ignore the result!

    I rather like this little engine, designed from the ground up for aircraft. For their own aircraft as it happens. Listen to that cute chug in the last video clip ☺️ Built to rev at 'airplane' revs, it tops out at 3000. Only thing is it seems to not be dual ignition, but I could be wrong. https://spiriteng.com/spirit-v2-engine/ This is the plane it's designed for. What a lil beauty 😍 https://aopa.org/news-and-media/all-news/2025/july/31/a-neat-little-package

    Yes, Cox have the glow plug built into the head. There is a diesel conversion for 049 but it's not very good. In the case of the 010 (0.15cc!) a regular glow plug would be nearly as big as the piston 😄

    Do the guys designing redrives not know all that you know? I'm being serious. In these discussions, some guys here have concerns about the engine design (for instance, the crank bearings not being built for the types of loads an airplane puts on them), others say it's mostly peripheral things that let them down, like redrives. I seriously feel if that's the case (and I don't know if it is, I haven't looked at failure rates) then that should be something SOMEONE must be capable of engineering properly. Ostensibly, the engine it's connected to is way more complicated. There seem to be some big players saying they've got it sorted. If they have, they should make that a HUGE selling point and offer their design to suit all the most popular conversations. Their GOOD product should crowd out inferior products in the market. What is for sure in my mind, is that along with most of these engines being single ignition only, you have three distinct areas (engine design, redrive design, single ignition ) that aren't 100% 'aero' that allow for a higher chance of failure than an actual aero engine.

    Bushcat too, and possibly the widest cabin in the ultralight category..

    Thank you so much for this ☺️
