Will The Worlds Fastest Airplane Finally Start?

[@Miranoff]

Hey, hats off to the guy in the last video comments who said the exact same thing about the harness wires probably being the issue. YOU WERE RIGHT BRO!

[@twistedyogert]

I told that guy earlier that I agreed with him entirely. I also suspected that it was grounding out somewhere. Every insulator has a certain voltage where it becomes conductive. I guess 70kV or less was the limit.

[@ScottsSynthStuff]

That was me. Let's just say I have some prior experience with this exact problem, and knew what it was straight away as soon as I heard the stumble. :) This time...I'm not 100% sure. He's getting NO spark. Perhaps an incorrect harness for the mag application?

[@RejectedOutcast]

[@richardbushey4134]

You're the one channel I can confidently LIKE before I even see the video. Thanks for giving us all the opportunity to experience a little bit of your journey in aviation. Everyone on your channel is awesome! Keep it up. Stay safe!

[@lyfandeth]

I found out about spark plug wires long ago, trying to improve an original Mustang with "better" wires. Found out the OEM factory ford wires beat all the expensive crap in the speed shops. Aged better too. Spark plug gap? I had a car where the drivers manual and full shop manual carried one number--but the pregapped OEM replacement plugs were always at a consistent different figure. At $50/plug, I hope they at least are platinum tipped plugs!

[@johnregan3732]

Darn, I was betting it was going to start right up! What could possibly go wrong? Back in the 70’s I was racing. We put a high yield ignition on my barracuda. Ran like K-rap. Changed the plug wires out for Shielded aviation/racing wires. Wow it sung! So I was hopeful. It was doing the same thing. Spark was jumping the wires. “Can I get a CLEAR PROP!”

[@acronutz]

Just a little detail on your bottom plugs. The reason these types of plugs are used on aircraft electronic ignition systems is the ease of obtaining the larger gap that can be used with the higher energy spark of the EI (which you did talk about). Regular massive electrode aircraft plugs would be difficult (if possible) to achieve the .035 or greater gap usable with an EI system. Electroair for example, specifically calls out the BY style plugs you had in the bottom with a gap of around .036. I run the same ones on my RV6 with Electroair ignition. Many of the experimental electronic ignition systems folks recommend regular auto plugs with similar larger gaps. For checking gap I use a piece of .032 safety wire from my tool box and set the plugs up for a easy/slightly loose fit of the safety wire gauge.

[@Creations-hj2kq]

Thought your at Oshkosh ... i was getting ready today to head to EEA and meet you....

[@GaryLordsWayMinistry]

You need to get some good spark plugs if you want to keep that thing running at peak power. I hope you put clamps on that vacuum hose, it's not like you can just pull over to plug it back in if it comes off. I hope it is sturdy enough not to collapse either from the vacuum.

[@Mdwells2944]

Make sure you have it in the “O N”position!! Haha heard that from a crew chief who just worked on an aircraft at Elmendorf AFB. Cracked me up!!

[@terrallputnam7979]

Jimmy, I am so excited to see you get Cameron going even faster. Just be careful getting used to the extra speed. I saw the Apache on Craigslist for sale. Hope someone gets it and makes it even better. God bless!

[@grippen5995]

[@mikeday62]

[@paultaylor9939]

Back in the early days of been a mechanic nobody told me the jaguar battery had been on charge over night ,took some jump leads thinking it might need some help in starting it and BANG !!! the battery blew up in my face just one small spark did it,luckily I was ok just had someone who knew what to do helping me. Jimmy !!! Carry on the great content cheers

[@vangogle1]

Just got to the end of vid. Great job improvising a test for the mags!! Looks like not getting power to them in the plane. Can't wait to see the rest!

[@MrDanoman812]

We always used a sand/glass blasting machine on our plugs for annuals. It works and saves a ton for the owners in replacing spark plugs. :)

[@jamesburns2232]

Be sure that ALL the sand and grit is removed from the plugs or you will cost more damage than replacing spark plugs would cost. 🤑

[@worriedman8634]

Spend Jimmy spend! We love to see it. The more it costs the happier it makes us viewers. Thanks for the videos, great stuff.

[@Mobev1]

Scam

[@naughtiusmaximus830]

I work with lasers at about 10,000V. They arc through just about anything if you damage the original insulator.

[@ondrejstejskal1989]

Nice project, keep going. W8 what about adding some winglets to reduce induced drag or add/remove something else in this manner or perhaps reduce some weight, it might help too.

[@victorm56]

HA, I was saying the same thing about your spark plug wires, I did something similar to an old sports car I had in 1976. Upgrade the ignition to a "Capacitive DIscharge" with a heathkit. It blew the high voltage through the stock plug wires. Upgraded those and double the spark plug gap. Smooth, more power and better gas mileage.

[@victorm56]

It acts like the magnetos aren't turning when installed in the engine. Or the spark isn't getting to the wires. Something grounded maybe?

[@DragerPilot]

Regaping plugs is not always as easy as it would seem. I have seen used plugs (not machine cleaned) that are cracked; but not on visual inspection. If it was me, I would buy new plugs that are professionally gapped. But that’s just me. I enjoy all your videos. You are my kind of crazy.

[@billyhaddock5540]

Congrats Jimmy, on almost getting the Plane to start after u did alot of work on her. lv ur crazy way of doing stuff.

[@StandForFreedom1776]

For you advance timing tubing, what like of pressure is being made. Does the yellow tubing need s clamp to insure it doesn't come off.

[@mrbmp09]

Pretty sure it's vacuum.

[@HunterDFtwo]

Question, are the harnesses not the same type for each Mag?, if they are the same why did it only effect one side?

[@robertschwien6396]

While they're on the plane, can you pull the harness off, put something ground by the mag outputs and test them. Just thinking those harnesses might be the issue.

[@mikeratcliff1446]

Thanks Jimmy. Things keep happening for you but you are learning and we are learning along side you.

[@kennutley5444]

The hole in your gap tool is to bend the spark plug tabs. if you pry on the center electrode you have a possibility of cracking the center porcelain,

[@derekddanderson1]

Just started watching more of your videos I really enjoy them and I totally dig your humor

[@danielwhite3929]

Perfectly normal to see BY plugs in the lower cylinder spark plug location they help prevent mag drops due to spark plug fowling with lead. That's why you saw lead in the plug - leave em there 👍

[@bobtaylor9288]

Jimmy I can’t find the video where you fixed the ignition problem What did you do to fix the wires and electronic ignition problem Thanks

[@PoasLodge]

I've seen that before on the lower plugs - trying to give the plug a chance to not fill up and keep it from oil fouling. If they knew it was oil fouling, this would be a kind of band-aid fix. Hopefully you're not passing too much oil past the rings.

[@joejernigan4015]

Spark jumping to the case or bad ground or the wires ? Can’t wait to see

[@madebylife]

Always good content. Personally, I enjoy a little goofiness. So many channels take their own selves too serious for my taste. I also despise reality scripted drama. Jimmy is far closer to my style of mechanics. All business when flying and prepping the plane but if you can't have fun then what's the point in living.

[@stevec7596]

You should get some griplock ties instead of those cheap zip ties. Also a lightspeed ignition would be the way to go. For you to get to 250 you're going to have to cut drag wherever possible. Cooling drag is probably the first thing I'd go after.

[@beckysmith7142]

Put E-Mags on the RV6A I built and using auto plugs at $2.50 instead of aero plugs at $20.00 a plug. O320 starts and runs great.

[@edspencer7121]

Mags shut off on a ground circuit. Are you sure your ignition switch is good? The ignition circuit isn't pinched somewhere to ground between the switch and mags?

[@larryburwell8550]

Your quest for more power, especially in the experimental realm of things, can potentially prove most detrimental, to put it nicely. Use the upmost of caution!

[@adrianmiller1971]

Always entertaining. I tune in for all the technical terms.....

[@randallsmerna384]

I may be wrong but doesn't the spark plug gap need to be measured between the center electrode and each ground electrode instead of between the two ground electrodes?

[@benjigault9043]

The bottom plugs are protruding electrodes, common to use on bottom so they do not foul as easy, some people also run fine wire on bottom only for the same purpose. Rem38Es or something on top and Rem37bys on bottom probably. Also saw you taxi in 310EB yesterday on Oshkosh live cams, she is shiny.

[@dalepatterson1748]

Dangerous Freedom is Expensive.. But, it is OH so worth it!! 👍🤗🥳 I have found that, MOST of the time, I only have to spend the big bucks once. After that, it's a matter of changing spark plugs and gapping them often... I always keep two or three spare sets, and have sets to swap out. Saves time.

[@Bass.Player]

Batteries out gas hydrogen and I have seen several blow up doing things like this. NO SPARKS near the battery.... And it's not just when it's charging!

Go to Harbor Freight and buy small beed blaster, you can clean Spark Plugs like new use smallest glass bead and small Air Compressor. Keep little more distance and max 80psi.it’s safe for cleaning spark plugs.

[@JS-lg7vm]

My certified IO-360 with SureFly EI has vacuum advance. The only major difference is that I can't run two of them. Still need a mag on the non-starting side (is what I chose).

[@erwinschmidt7265]

Jimmy - I've gotta admit, that thing is really really quiet!!!!! I had neighbor who bought new Jet-Drive boat, that was supposed to be fastest on lake, lost $500 losing every wager, 7 trips out to Marine Dealer, lost another $1200 being loser, so said I'd fix it, but it would cost 'em case of Corrs. Motar was Turbo Ford 460, and Gawd it was purtty!! Took glance at wiring, and spark initiator wires doin' it side-by-side held there by Ford Official genuine black plastic hoops, as this sucker was factory man!! At RPM, this Super Boat's Motar was cross-firin' it's sparkalotors to beat the band to just go 112MPH = Piss Pore!! I snipped the hoops, freed the wires, ran them perpendicular, which made it look like a fazed out lady of the night, but when fired up, it ran like a rapid ape!! We got our speed equipment out, 2 pair of swim trunks & 2 pair of hold-me-tight sunglasses, & neighbor drove (Piloted) us 148MPH! Neighbor made his lost bets go away about 12 fold, AND I GOT MY BEER!! Sometimes ya just gotta jump thru the hoops to make your motar very noisy...good luck with the plane Jimmy!!!

[@mikeperry2814]

I'm guessing the electronic mags need a high current power source using a couple relays (fuse protected) connected to the battery, and the relays powered by the ignition switch...??

[@bubbagreensmith7174]

Jimmy is so hyper he makes coffee nervous 😆

[@dagger4146]

Power leads to the mag switch, it's possible the switch is bad. Separate leads for the starter function lets the starter engage, but if the switch is bad it's cutting the flow of juice out of the mags by opening the circuit. Simple to check with an ohm meter.

[@AkihikoTakeba]

[@kyletidwell515]

[@MrPuckchaser]

I think investing in a spark plug cleaner, Which uses compressed air and some type of abrasive bead to clean the spark plug immaculately and doesn’t harm the surface, Would probably increase the life of the plug and the firing efficiency I believe when I had one I bought it through snap on

[@bbrut3332]

Ahhhh, the old sparky plug cleaner that were in every mechanics shop that I visited in the 50s, 60s and 70s as a kid growing up. Yep mechanics used to clean and regap the plugs in days gone by.

Left mag turns the oppo direction doesn't it? Perhaps all you need to do is swap the 3 and 4 plug leads on the left mag?

[@mikegoodman447]

It appears both turn the same way but the two are not both facing the same way both are offset so one sits 180 degree opposite the other. So where number one may be say at the two o'clock position, the other distributer number one would be in the 8 o'clock spot. Firing order would remain the same and number one hole would be the same spot.. It would just look a bit different when viewed from the back.
