They obviously know what they are doing.  It was an instant start!!!.  Also not a sport for an old man like me - way too fast.   LL~

Why is it when people share something on here that certain people just want to find fault with anything and criticize?  I don't get it.  The man who was flying the jet is and experienced pilot and has been flying these things for years and Walter you want to question his piloting skills?   You cant even build a Thundergazer correctly and you want to criticize someone else?  How much experience do you have flying one?  

I am tired of this constant demeaning of people when they try to share something and there are people who want to find fault with anything.  Some people on here would grade a love letter from Raquel Welch for spelling errors....give me a break.

neat post.

What fuel?  Methanol?  Do you have trouble with humidity down there?

You kept it on the ground for quite a bit.  We let go as soon as we hear the roar.

We fly a lot of jets for demos off grass, bigger wings, gear with big tires.  Only about 90 mph, but people love the noise and the quiet when they shut off.

There is a big difference in power on vs power off elevator response. 

I will have to try to get an air tank we go old school with a model T coil and a tire pump.

Hey Mike there are some in every crowd and we have to learn how to ignore them.   People say I park to close to the circle when I can.   Saves me a lot of steps with theses old knees.   A few more flights and I bet he get that jet in a groove that will add to the mph.    I remember back in the day when I was told that a stock Dyna-Jet would do 150 mph with out breathing hard.   Good video, keep them coming.  Thanks,   H^^

Dave I was doing the filming but I remember Mike (the guy flying the jet)  saying the fuel was 80%/20% and one of the components was Methanol... I don't know which percentage though since I am a spectator when it comes to these jets.

thanks 80% methanol 20% nitro is a standard mix.  we used to run them on Coleman fuel, but the 80- 20 mix seems to be a lot less sensitive to jet size.

So many things wrong with that. Peoples observations/suggestions are not always insults, it shows your temperament. The insult you made to me about being a bad builder was uncalled for. I can build/fly any speed/racing plane but, coming from that background, modern stunt construction is something new for me and you're a bad ambassador to the sport for shunning a newbie like that. Do you want to be like the people you're complaining about because, you've succeeded.    



It's a Jersey thing,
MM

The only thing wrong is that I just should have considered the source.

It's a New Orleans thing.

The whistling noise after shutdown is new to me.  Was it still running at low power or was it something else?  Looks like fun.

Russell I honestly don't know.  I have never flown one of these and know very little about them.  I was filming the flight and was just trying to keep the camera on this screaming bullet.  The sound is something my ears will never forget.

Hi, Jets are a lot of fun; but you do need a nice venue for flying them.

I'm very impressed with the quick start. I haven't flown my Cat-Jet in

 several years. It was a bit more reluctant starting; but once it ran,

it was very easy to restart.  My best flight was 156 mph using Coleman

fuel which requires the stock fuel jet.  I used  a tailpipe probe, bypassing

the spark plug. I got lots of great help from Dale Kirn and others no longer

with us; when I first got started with jet fun.  I cannot tell from the video,

but I'm guessing the model is a Sport Jet class design which requires external

controls and standard formula fuel.  My Cat-Jet is a late 1960's speed trainer

design with an internal control system. which reduces a lot drag.

The whistling at the end is air passing through the reeds with no combustion. I heard Danny Banjok say he uses regular gas in his mix (don't forget the propylene oxide). I have zero experience with pulse jets so I can't offer any definite answers.

Bill  he had a camera mounted to the front of the hard hat to film the flight.  I think the hard hat was just a stable mount for the camera.  I am not knowledgeable about these things at all.  Everything I know about flying these things I learned at the field Wednesday from Mike who was flying it.  I think I have a few still shots I took while it was on the ground.  I will try to post them too.

If you listen real close, you will hear my good friend Myron say he was going to watch from the other side of the fence.  He was of course kidding because he is the one who started it.

I wish my brother Bob was still with us so he could tell of his first experience with a pulse jet.  As I remember it was the 1970 Navy NATS and we heard the jet being fired up.  He said he wanted to go see it.  We were still in the camping area of the Naval base.  A few hours later he came back with a big grin on his face.  He said it was fantastic and wanted one.  Seems he was watching a couple guys getting ready for a flight.   One asked him if he was doing any thing, of course his reply was, no.   He was handed the air tank and told to follow them.  They got on the circle and was ready to fly.  He was told to take the air nozzle and point it into the front of the jet and press the trigger when he was told.   Yes it burped and he took off only to realize it was not running.  The third time the guy says lets start it this time.   Next thing he knew it coming around the circle.   He helped them with their other official flights and thanked them for the experience.   Even at Muncie you can tell when it is jet day.

hi Mike, I'll look around for some; although I don't think I have any digital pics of it.  That means I'll have

 to take some pics and figure how to post them on this forum.  D>K
