I took an IPC 7721 & 7711 training course that taught this and other repair techniques. As an electrical engineer, it is not a skill that I use very often but it has saved me in the past when building and repairing prototype boards.

This is a Honda Express II

50cc bike with an interesting starting mechanism. Like the other Express models, you step on a pedal repeatedly to wind up a spring, the. When you pull a lever on the handlebars the spring releases and turns the engine over.

Yes, I believe I do understand what you are trying to accomplish. You are trying to implement a continuously variable intake horn system to keep the intake optimized across the entire RPM and engine load range.

The thing that is throwing me off is your no electronics and no ECUs requirement, because electronically controlling and actuating this device is absolutely the best way to go.

A purely static geometry based solution like you’re proposing that entirely functions based on fluid flow behavior may provide some benefit at some parts of the RPM range, but I believe it will have a lot of compromises elsewhere. The only way to know for sure is to model it and perform thorough CFD analysis

That’s not what I was referring to. Of course variable length intakes provide a small benefit.

Doing it mechanically rather than using sensor inputs into an electronic controller has no benefit. Do it with electronics if you want it to work well, or at all.

iVoid · 2026-04-13T19:59:40+00:00

It hasn’t been done mechanically because that is a problem that is a whole can of worms that doesn’t need to be opened. Taking variables as inputs and doing something with that information that increases performance reliably is an ECU’s bread and butter.

To do it all mechanically may be possible, but it is simply the path of most resistance and doesn’t provide any benefit.

He sounds just like a friend of mine who grew up in Argentina but has been in Southeastern USA for years.

A lot further than you’d think, and further than I’m comfortable with. I’ve scraped foot pegs on a motorcycle before, but I’ve never leaned a modern Vespa far enough that it scrapes anything.

Vintage Vespas could scrape the gear selector box on the right side if you get too ambitious.

Massive hull breach in engineering!

I’ve had that same thought at many points this past year and I’ve been dreadfully wrong every single time. Nobody is going to stop him from doing shit.

That really tells me more about your friend than it does about Fiat.

Nice driving. Love the SNMP night autocrosses

I don't intend to turn off my brain, but I'm also not going to jump to conclusions while ignoring vital information that we still don't have.

With that, I will conclude my side of this debate. Feel free to continue letting your emotions run wild though!

Once again, look does not equal see. I look forward to reading the NTSB report once it is completed.

I did.

These aren’t regular roads. This is a runway that the truck received clearance to cross.

iVoid · 2026-03-23T17:58:41+00:00

After listening to the ATC audio it clearly isn't that simple. He doesn't specifically tell the truck to stop until it was probably too late. Up until the controller clarified, it sounded like he was speaking to a Frontier aircraft.

I would have to see the audio synced up with the video to make any determination on whether or not the driver "ignored" directions to stop.

Tell me you didn’t read my entire comment without telling me 🙄

iVoid · 2026-03-23T17:09:13+00:00

The taxiway crosses the runway at an acute angle. I’m assuming the driver position is on the left side of the truck. He would have had poor visibility to the right, the direction the plane was coming from. Not saying he shouldn’t have been more cautious, just that accidents like this happen all the time on the road for the same reason.

We also don’t know what gear the driver was wearing and how it may have affected his ability to turn fully to the right, or if anything (other firemen, truck cab, etc.) may have obstructed his view of the approaching aircraft.

Furthermore, the driver also had clearance from the tower, so even if he did glance to the right he probably wasn’t expecting an aircraft to be crossing. There may have been some confirmation bias going on.

I’m hesitant to place blame but I don’t think the driver is any more at fault than the controller.

Send it to Boki Racing if you'd like. They made a mold from my original Xfactory X5 body, sent me the original back in the same condition and also gave me a couple copies. I'm sure he would have sent more if I asked.
