Hobbyking Pulse Jet Gasoline Engine "Red Head" with Ignition System

Have you heard the BUZZ? Pulse jets are the Bees-Knees. 

Pulse Jets are not new, they were around before the turn of the century.  They were made famous however when the Germans used them to power the V-1 flying bomb. These were dubbed the “buzz bomb” due to the distinctive sound made from the pulse cycle of the shutters and combustion at such a high rate.

Jumping forward a few years, due to their simple design they made their way into the early days of modeling. Pulse jets were used by the hardcore modeler breaking records and they strapped them to anything that moved! Anyone that has ever seen or heard one run in person will never forget it.

The HobbyKing Red Head Pulse Jet is a retro flash back to the days of modeling where nearly everything was an experiment and the possibilities were endless. Anyone that has ever seen the old pulse jets have instantly had ideas (some smart, some not so smart) of strapping one to something or another. Now is your opportunity!

The Red Head Hobbyking valve pulse jet is classic in design and yet modern in quality. It runs on just plain old gasoline (no oil needed), starts with a bicycle pump and comes with just about everything needed to fire it up including the ignition system to the mounting hardware, spare parts and reeds. 

Hobbyking’s Red Head Pulse Jet Engine is perfect for anyone looking to feel nostalgic and strap it to a model, place it on their mantel, or take into the garage and upset their neighbors.

Back in my early Control line flying days (50 years ago), I saw these "Dynajet Redhead" jet engines operating. The sound is unmistakable, and the power and speed they generated was awesome to behold. I was at a contest when a scale US Navy jet model, powered with one of these Dynajets, impacted with the ground. Parts were all that were left, and one of the wheels hit a kid standing well outside the flying circle so hard it knocked him over. I'll always remember that!

is it poss,to put an inline neddle jet to controle the fule rate / or do these engins only run at full power. could you tell me the weight of the complete engine inc,. brackets please. Many thanks B Woodcock

It is possible, I have seen pictures of the Dynajet, which this one is very similar to, with a RC carb installed on the front. I believe that it can only be throttled down to about 50% power before it quits. It would require machining to the intake by an expert. The Dynajet could put out 4-3/4 lbs thrust so it may have been larger. I had a friend that set some of the control-line jet speed records in his day.

I would like to say : Why a so big difference in the price with a turbine ?
 tab76123 32 points
They are completely different type of engines. The pulse jet does not require precision high temp high RPM bearings, extensive metal machining operations, a fuel pump or an electronic control unit. A pulse jet is much louder and has a much harsher noise than a turbine. They cannot be throttled.

I hope HK will start selling spare reed valves for these pulse jets in time, very important replacement part that should be offered for sale.

Hi all, I purchased this 7 days ago, got to me in Australia in record time, thanks hobby king My pulsejet was better quality with regards to welding and oval shape as listed in rv model reviews YouTube video, so maybe one for quality control, but I got. Good one so I'm not complaining. I wanted to see if it actually works, and it does! Nice and loud, I followed the instructions included, and it all works well. Awesome petrol to noise converter!

Pulsejet arrived today, took two weeks. Body is made from relatively thick stainless steel compares to other pulse jets and the welding is satisfactory. They did get a little over enthusiastic with the grinding down of the welds on the outside though. Valve head is nicely machined, but it is covered in small but sharp burrs, including where the valve closes, preventing it from sealing. After deburring, all looks good.The mounting straps are excellent and the ignition system works really well.

Cant fault the valve head, mine was perfectly machined . The weld was a bit uneven, but what the heck only about $99! what do you expect foryour money!
Bad news is I could not get a consistant start, it was either too lean or flooded, mind you the air temp. was 2 degrees C!. Too cold perhaps?
Anyone got any Hints? was using staight unleaded petrol tank approx 10mm lower than jet.
Possibly an in line needle valve?
