I totally agree with this, Pulse-Jets have been around for years but are in the spotlight now because they are suddenly very affordable.

The attention generated here on RCU and other forums will ensure plenty of them are sold.

My prediction is that the majority of people who acquire these cheap pulse-jets will buy them, try them and quickly retire them.

I agree. The sound is so very disagreeable. About the only reasonable way to operate one would be to fly out in the desert with no one around like Bruce Tharpe does!

I think that is funny that some people think that pulsejets are loud, dangerous and should be banned.

Ever seen boom cars driven by kids on energy drinks or worse?

You guys do realize that you are arguing with an individual with a mere 6 years of r/c experience under his belt qualifying him as still a rooky, look at this Vettster fella's very first post on the subject, he demonstrated his lack of knowledge base right out of the gate by stating how dangerous the PJ was because, 1 it gets hot, and 2 you can't kill the monster once it has been awaken, even though it was and is obvious it is fuel fed and could and can be shut down with a servo impute at any time. You want to know who participates in the really dangerous part of our hobby is?
































Those Old Free Flight Boys, the nerve of them firing up those noisy little bumble bees and then letting them go with no regards to throttle or directional control... LOL.. Here's your sign.

Wow! such negative comments coming from people that have never done anything! for their clubs.

And Ive been flying 8 years now. 7 of them have been with turbines.

Think Im going to ban FPV today..LOL

I've posted some pulse jet operating procedures in the "The Clubhouse" forum under the "This is the Danger...." thread. I've also ordered the HK pulse jet and will further comment on this engine upon receipt.

Welcome to my club Sir, I had direct responsability for its design and building among with my friends. Pulsejets are welcome at our club, as long they respect our safety code of procedures. However, they are a rare sight this latest years, as most of the club members fly turbine jets.

I don't think they are dangerous. They are just WAY louder than any club (in suburbia) is going to allow. And since there isn't a throttle on them... they aren't much fun.

My Feedback: (13)

I take it you don't like pylon racing either? How can an event possibly be "FUN" if you don't have a throttle on your engine/motor, and the noise that those pylon racers is just ridiculous?
Very myopic observation.
Admit it Dr Honda, you just don't like pulse jet engines, pulse jet planes, and the people that fly them. That is fine, but don't condemn a whole area of our hobby just because you don't like it.
I'm moving over to the other pulse jet thread...this one sucks.

PS....Your Signature isn't really a signature, it is an advertisement for your business, and isn't even related to the RC hobby. Not even sure if this is allowed.

And Welcome to MY field Sir...

Note the town of 500 people directly South of the field 1 Kilometer away. Note the Forest to the W and N of the field.
Note the farm fields ALL around our sod farm that is growing corn 8' high. Note the Houses directly W of our field. Note that this year the police have paid us a visit because the neighbors in the town had complained about the NOISE from a 30cc gasser.

Note that you should not presume that EVERY field in the world has a 3000' paved runway with Zero obstructions for miles around and identical to yours.

Note that to get permission to fly on our field that I had to lobby MAAC for 5 months to change their out dated rule that states that Clubs cannot operate within 4klm of each other. I was successful at that. What does this mean? It means that not only was my club permitted to move within 2.5klm of another club...But that ALL clubs in CANADA are now permitted to more easily open clubs at time when finding new field locations is becoming harder and harder.

I did all this in my first year as president. Our club charges $20 to join and $5 a year to renew(not a typo) So if someone has a problem with not flying the Dangerous and Extremely LOUD Pulse jet engine at our field.. They are more than welcome to take their 5 bucks elsewhere.

enough said..

From the vastly experienced club membership who have bought into your prophecies of doom and destruction no doubt. Maybe even from the guy who nearly creamed me with an OS .61. The guy who attempted to take off his Etrich Taube through my torso I think is long gone however.

There is nothing wrong with protecting a flying site and your club by avoiding offensively loud models. "Dear members - due to the operational noise level of pulsejets we cannot allow them to be flown at the club field." No argument there - they are LOUD.

But noise is not danger. Claiming they are dangerous publicly in capital letters is fear mongering, plain and simple. Save this for the local soapbox.

All model engines are dangerous in the wrong hands. RC models are dangerous in the wrong hands. So are ball peen hammers, rolling pins, lawn darts, several common kitchen implements, baseball bats and pry bars.

Pulsejets are no more and no less dangerous than all of our larger model internal combustion and turbine systems. We are required to follow the same safety code as turbines, and by doing so this ensures an equivalent level of safety. Throttles aren't required for safety, but engine cut off is. Funny, not for glow models however. With the huge popularity of turbine engines and models, off the shelf models capable of 150-200mph speeds and with complex gear installations, we are already at a point where an equivalent level of potential hazard exists as a norm in the RC club environments. Checkout the crash and burn turbine videos al lover Youtube.

The only two fatalities related to RC modelling I know of in the last decade or so are from RC helicopters. Are they allowed at the club field?

If somebody could post some bona fide evidence that shows that pulsejets are somehow more dangerous than other popular forms of modelling rather than pointing out the obvious fact that they are more dangerous than sitting in front of a computer*, the doomsayers would have something to point to other than a copy of Chicken Little.

* I tend to think more people have been injured or died at their keyboards than at the hands of pulsejets, V-1 notwithstanding.

Of course friend. Those that agree with something speak up while those that do not normally stay quiet in the background. Have a club vote with secret ballot and you might find you aren't that right after all. Make sure ALL the members get to put in a vote and not just the few that show up to meetings all the time. Remember ALL members pay for the privilege to fly in your club right? You may be suprised. Pulse jets can be dangerous. so can a car, a lawn mower, taking a bath next to a radio or walking down the street. I will use mine to chase the birds out of the trees. lol.... then put it on a nice plane and fly it. Since controlling it is SIMPLE not hard with a simple fuel cutoff I wont be worrying too much about this so called uncontrollable monster. I agree they are loud. So most folks will find areas that are safe away from others and enjoy them. If compared to something like FPV I would pick the ram jet every time as the safer of the two. I know several beginner pilots still barely getting a trainer off the ground that have decided they need fpv and THAT my friend is a scarey thing....

erbroens

And you should not presume either that our 600 feet runways magically appeared in the middle of a appropiate place to fly.. It took decades of commitment,hard work, research and money from all the club members to make the best r/c club we could make.

Of course, all that work wouldn´t have been necessary if we banned or badmouthed any aspect of the hobby that didn´t fitted the current facilities or our perception of safety at the time they appeared,,.

Nice field. The club has moved more times than I can counted in the last three decades. Tough when there are so many sod fields around but it is so hard to get permission to use and continue using them. You should protect that effort jealously. And obviously flying pulsejets that close to Baxter would be a dumb idea.

From my perspective I have zero problem banning them from your field due to noise sensitivity. They are grossly, offensively loud. But that's it.

But I do have a problem with you posting "Dangerous.. pulsejets" on an internationally read forum when in your own pictures you show that you fly turbines on the same field. Without direct experience, knowledge or evidence to support the theory that they are more dangerous than turbines (because there isn't any), unsupported fear mongering should be avoided. The rest of us have enough problems without a self-proclaimed prophet exclaiming the evils of pulsejets to the world.

I actually do have access to a massive field to fly them with two >2000' grass runways, in the (relative) boonies, and I can do so legally, safely, and within the constraints of the MAAC safety code and with the field owner's permission and without pissing off the neighbours. So I am no threat to your club, to MAAC or its reputation, or anyone else - any more than you are. And as an aside, I have had a direct hand in affecting federal regulations (the CARs) to the benefit of MAAC and other modelling associations operating within Canada - this is primarily with respect to model and high power sport rocketry, not fixed wing, but it counts in my books. This was accomplished by suppressing the fear mongering others and educating TC (and other agencies) about that area of the sport, the mandatory safety codes, and what it is the participants really do with the stuff and what it capable of. As a result there are regulations in place now that allow these sports to continue unhindered as long as the safety codes and all regulations are followed, and those rules and regulations are quite livable and reasonable.

I am firmly on the side of doing things by the book and staying safe. I am not a renegade modeller.

OMG!!! The sound of rubber bands being wound is just too much! And dangerous!! One might snap and put somebody's eye out!! Uncontrolled model airplanes? We need to ban all Freeflight airplanes!!!--- Sheesh!!!

I remember when pulse jets fist appeared. I think it was about 1946. Nobody thought them as dangerous. I flew one ona control line under the lights in a ballpark in 1950. With the audiance about 50 ft away behind a chickenwire fence.It made lots of noise and little diamonds formed in the exhaust For the second flight I think everone in that small town came to see what the noise was. They loved it, especially the kids

Byrne 1157 it's not always about SAFETY,,,SAFETY,,,SAFETY,,,it's about respect. I respect my neighbor's right to the expectation of peace and quiet. That is why I would never start my pulse jet in the house with the windows open.
