Re: 95 octane vs 98 octane grade gasoline

Use the lowest octane fuel you can buy. THis will give you more power and easier starts. We have a thing called white spirits which is sold in the hardware shop which is a form of very low octane petrol. Personally I stay away from any fuel with petrol as it is to difficult on starts and power. All ...

Re: White gas for the HK Pulse jet

Yes it would be absolutely fine to run this fuel. And the metering jets supplied are setup for this fuel.

Re: New to the Pulse Jet forum- HK Red Head fuel consumption

I have been running 80%methanol and 20% nitro in mine for control line flying and a 200ml tank lasts 25-30 seconds on petrol you would half the tank size to get the same flight time so 100ml for 25-30 sec run time.

Hope this helps

Re: Hobby King Dyna jet

These reeds will fit the Dyna jet , Bailey Sportjet, Jetbill sportjet and the OS jet, and probably a few more that take the dyna style reed.. These reeds are very very well made

Re: Best Air Temperature for Speed Records

Flying very low on a hot day to get the extra heat from the tarmac makes a little jump in speed. The Warmer the air the less work the engine has to do to warm it!!!! Colder or wet days are usually slower.... Metering jets in 1 thou steps make a difference even if you can get the 1/2 thou sizes makes...

Hi John I am at work so only have microsoft paint to make a up a drawing for you.. This is the system we are all using for the sparks but each of us use different air bottles. I use a scuba tank and have it set at 60 psi. I think Patrick and JB ran 65 psi and The Robinsons 55psi. They all work reall...

Re: jet flight

Hi Jerry I would love to come back to Muncie one day. Last time I was there I managed to win the fastjet title in 2010 being the only non American to do so.. It's going to be all down to finance if I ever make it back.. But if you didn't know Andrew Robinson managed to break his fastjet record here ...

Re: Which fuel produces the most thrust?

50% nitromethane and 50% propylene oxide will definately knock your socks off... Makes a huge increase in power on the stock pulsejets

Re: Help with a Tiger jet

Hi I would try another type of fuel the unleaded gas from the pump is very difficult to start with the little jets. The original gas they used is what we call in NZ White spirits or I think in the US coleman lighter fluid??? try this if you can?? Also the valves need to seal well. Try blowing down t...

Re: How much thrust?

Hi Guys for the atom jet I wouldnt even think about running a 8 thou reed valve. 6 thou would be thick enough and I would even think about 5thou.. All these materials are readily available. Just need a quick check online and you will find them. All my valves I made for the standard dyna/baily/jetbil...
