Plans or kits for something to put an HK Pulse Jet on.
« on: May 22, 2014, 05:35:24 AM »
I have an HK pulse jet on the way.  I found the Tarfu plans online but they are the only ones I found. I saw on a Whittier youtube video someone mentioning the selling kits that that HK fits but can't find any more info on it anywhere. I would prefer to do something 2 line not mono. An already proven kit would be nice as I won't have to order stuff from multiple places.

Looked all over there the other night. Saw lots of vendors for engine speed nothing for pulse jets.
Never did any speed flying so I am not sure how much I will like it. If I think I will be doing it awhile I will join NASS. But not doing that if I get one or two speed planes and decide its not for me.

A local flier pointed me in the direction of ad for some laser cut Sport Jet Pod Racer kits on the flying lines flea market.

Bud, I bought one of Jim Booker's Pod Racer kits last month. Very nice kit, for $100 you get the kit, the tank and all the mounting hardware. He will Email you plans for a dolly made just for the Pod Racer. Jim is a great guy, very helpful. I don't know how familiar you are with pulsejets, but the HK pj needs some mods to the flowjector and main jet to get good runs on. Good luck post some reports for us. Mike

Jim is out of kits right now and it will be some time before he does anymore. He said he will email me when he knows when he will have more. Since I have never done a speed jet I am not real keen on scratching one. So the HK is either going to sit on the shelf or go in a self designed pulse jet stunt plane. Only problem with the stunt plane is I am having a hard time finding a new cline fuel regulator for an already proven 24-32 ounce fuel system as they no longer produce them. There is a company that makes a similar one but I am told they do not work as well as the cline.

Bud, will you be using a metal tank or pressure feed?  I too have a pulsejet stunter in the works. I will take a different approach than Dan B. did with the metal tank. I am using a cline valve with a bladder. So far my test runs have worked very well. Using a bladder with a cline valve eliminates all the headaches of a metal tank. Since it is pressurized you can put the fuel bladder anywhere and it won't matter. I have test run with the bladder 4 ft away from the engine, holding it way above and below the engine. Since the pressure is constant the engine does not go rich or lean. This should work well for a stunter. The other advantage I see with this is that I will not have to put 30 to 40ozs of fuel in the nose, changing the CG drastically during the flight. I am going to use a foam wing with a bladder tube right on the CG, just like combat planes. Have you tried Bruce Tharpe for a cline valve? I got mine from him about 3 months ago. He has been running pulsejets on bladder tanks for well over 15 years in RC planes.  Here is a link to Bruce, just call him up. I think my cline was $65 shipped. http://www.btemodels.com/   Mike

Actually my bladder plans I am using were from Bruce. I will email him and see if he has a clines left. As for the plane I was at one time thinking about just converting his reactor to control line. But he says it may have some pitch issues due to the thrust angle. Since this is the speed forum I will make a new thread in the stunt forum for us to continue this discussion and post a link to it here.

Bud,
Assuming the HK is similar to the Dyna Jet here is a good starting point. Only thing I would change is use 5/32" for the fuel pickup line instead of the 1/8", it will make the take-off and starting much easier.

If you are looking for a big jet stunted there was a ship called the"Thunderhawk" that was designed around a Dyna jet as the Martin Thunderhawk. World Engines took it over for the OS jet. Can't find plans but a few people had them.

Best,   DennisT
