Default RE: P-20 Airframe Thread

Hi All,

I am a bit confused about the position of the engine tail cone in respect to the pipe bell mouth.

Is the engine tail cone positioned 20mm inside the bell mouth or 20mm outside the bell mouth?

Thanks in advance.

Kind Regards, Craig.

That seem to depend on which pipe you use. Always follow the manufacturers advices.

The bellmouth on the Als hobbies pipe is so big I dont think it will make a very big difference how it is positioned. The more you put the nozzle in the pipe the better off you are if you should have a bit of a litl gas plume on startup

Guys, the pipe from Ali is the same pipe as the one I supply and have manufactured, the bell-mouth is made so its identical to the specs of the Jetcat pipe so keeping everything as it should be.

In terms of position here are the JC specs, and suggested position, its how I did the Habu conversion for Ali etc with no issues.

If you want someone to test an HST pipe against a standard pipe I have a Jet Teng L39 with a P20 that could use a little help. LOL

Mike


Hello Mike ( Bald Eagle) - sorry can`t find your e-mail adress or our conversation in detail.
Do you remember the pipe I have sent you ?
What are the results ?

Cheers

How about a Flying Fox?

I've seen this fly a couple of times on EDF and it goes pretty well (and it looks better in the flesh than it does in the pictures!).

Well it looks like the HK Hawk is finally here, although sold out already and i'm not surprised at that price. They also have some scale electric retracts to go with it.

Complete steal for that money. I'd guess these jets are always going to be available in limited quantities since they probably only have a small number of moulds. Hope it comes into the new HK UK warehouse when it opens for business. Have just joined a club with a fab tarmac strip so would be perfect.

I wonder if the Hawk comes with loose inlets as the CMP one does... so that you atleast have the choice to make new ones without having to repaint the whole fuselage.

Yes they do. It was on HK's video. I think it is the CMP... just in new paint.
