[@BricoleurTV]

Nice one Jonas, love seeing you fly a proper plane again, and love seeing Tom! It´s a well known fact that most of the noice comes from the prop, regardless of mufflers or even power-plants (electric), the noice is more or less impossible to get rid of.

[@michaelgillogly3551]

I’m just stoked you have a Kitfox again!!!!!!

[@MikhailSharpowicz]

At Sisteron airfield where E-props are manufactured, they are running a 5-bladed (i think) silenced 'home-built' DR400 tow plane. It is inaudible at 30m on idle and taxi settings. It sounds more like a normal plane at full power however. All this reminds me of a video I saw of the Vietnam era YO-3A. The designers went almost all out to design a quiet engine, prop and airframe combo. Massive loss of power from the silencing though!

[@RedNeckWelding]

Your ads are the only ones I will actually watch, love the comic relief! When are we going to see some Glasair content? I’ve got a TD1 I’m working on an engine and panel swap.

[@John-N797]

Jonas: So why are we not landing on it? ...I kinda wanna try it!!!! That is just so Jonas like....Always trying things that others avoid... you've got to love this guy 😂

[@portnuefflyer]

Well it's back to the drawing board! I thought I could get away with rigidly mounting the muffler itself, with the flex pipe leading to it being flex hung, turns out I can't. The joint at the flex/muffler junction keeps coming undone/worn. This explains why car mufflers, even way back on the tail end of the exhaust, are still flex hung in some fashion, so no surprise and I suspected as much. In my 1500 hours or so of an earlier install, the muffler was NOT way back behind the cabane but under the boot cowl AND it was flex mounted, and it worked just fine. I tried the new location as it just looked better, also for CG purposes, but by the time I devise a way to flex hang it will involve other compromises of weight and drag, so my earlier further up flex hung location was better after all, it just looks funkier. A day later: muffler now re-hung, on rubber type automotive type hangars.

I have never heard anyone say they didn't want to be obnoxious and an airplane I appreciate it

[@boydw1]

Jonas - re the decibels, +10dB is 10x the energy (if it were a speaker, you'd need 10x the watts driving it to get 10dB louder), but +10dB is only perceived as approx twice as loud.

[@rsbrehm]

This is what A.I. says, "Decibels are a logarithmic unit that measures the ratio of power or intensity. This means that the intensity of a sound doubles every 3 dB. For example, a sound that is 10 dB is 10 times louder than silence, and a sound that is 20 dB is 100 times louder than silence." So it is exponentially louder.

[@cybertuffguy71]

You should hear my Remos G3 with a 912ULS ..... its like a stealth plane lol

[@portnuefflyer]

Those slick type go fast Euro planes ARE quiet, and who knows, maybe the clean airframe helps a bit also. I'm always aurprised how noisy the 7 is when flying dead stick, lots of wind whistle.

[@woodsmn8047]

clear back in the 70's I saw my first powered ultra light it was a hang glider wing with a small chainsaw engine about 6 or 7 HP and I chased him from Arimo to Downy on my dirtbike his speed was about 35 MPH and I watched him land in about 50 feet on tiny wheels mounted at the ends of the guide bar on that Downey airport strip .. oh and he came from Pocatello on less than a pint of gas

[@billroberts9182]

If you do an off-airport landing, 1st time, stop and walk it before taxiing and take-off. A rock or stump or hole could bite you!

Yeah totally agree. Hard to see everything from the cockpit.

[@Pipedktr]

Deci: 1/10 Bel: Base 10 log unit Many sensory nerves function on a Base 10 log scale. Trust the electromechanical sensors and not your ear’s perception. 0:15 Look up a sound pressure scale. Compare your readings to that scale. Ear damage occurs at a lower heard sensation than expected because the semi log scale compresses the actual sound energy stimulus. It takes a logarithmic increase in the sound energy stimulus to cause a linear increase in heard sensation. A small increase in heard volume is caused by a logarithmic increase in sound energy or pressure. Dr. T

The Prince is quieter and has a deeper (better? to my ears anyway) tone than any prop I've tried, including Kiev, WW, Warp, E, and Luga, but that's just a subjective opinion.

A glass pax would quiet it down quite a bit

7db is about double the sound pressure (i.e. twice as loud)

Take Trail Creek road from Ketchum, hang a left at the base of Mount Borah, eat in Challis, hang a right and go thru Double Springs Pass, then head south to Pass Creek on the right, that's a pretty spectacular drive, an even better flight, when it's early in the morning.

Get a folding ebike with a extra battery or two to swap out

[@portnuefflyer]

I have been flying with a Montague folder, three different ones, for the last 20 years, the last four one that I converted to a 1100 watt "hotrodded" BBSHD motor, I can carry two 11.5 amp 52 volt batteries in an external pod, and charge them while flying. A Rohloff hub means 14 real gears, it's about the ultimate e bike that can fit in the plane, but it's overkill for short rides on pavement, more capability then needed, and at 56 pounds not real light. So the little and light Brompton is just something to ride when I don't need a full sized ebike, and it's actually pretty fun to ride.

[@MerleTrisch]

[@superbill9066]

Id like to hear an update on Tom's injection system. Was it worth it?

[@portnuefflyer]

So far so good! Already, with cooler temps arriving, it's been nice to not to have to worry about carb ice on long throttled back descents. I learned, almost the hard way a few times, that once the oil temp dropped below 140, throttling back on short final could lead to the engine dying, but weirdly enough it also instantly re-started when cranked. Call it incipient icing, nothing ever in level flight or at normal temps, but the EFI eliminates that. Great starting always, smooth running and shutting down, and as expected about the same economy as before, due to my constant use of a HacMan manual leaner when I had the carbs. But unlike using the HacMan, I don't have to remember to enrichen it back up or otherwise mess with it, about 150 hours on the system so far.

[@stoker7211]

I'm sure you realize the corner you're painting yourself into by insisting on flying from the right seat. Rag wing right seat, no problem. 2+ pilot transports are flown from the right seat about half the time. But there's a no-man's-land in between. You'll suffer greatly if you ever move into complex single pilot aircraft operations and aren't comfortable flying from the side of the panel they were meant to be flown from. Someone like you will only continue to grow in skill and ambition where aviation is concerned. Don't wake up with your legs crossed when opportunity knocks.
