Hi Dave,
Have you flown the Jetwelt JP?

Hi Reuben, no I have not quite finished it, nearly there. I flew the smaller 1/6 scale one yesterday for the first time in its finished paint scheme, I really enjoyed the one flight I had, but had to stop due to some contamination in the main fuel tanks. It turned out to be silicon sealant that I used to put the overflow pipes in with so I won't be using that again.

Hello Dave,
Looks cool! Does that have a P80 in which case where did you locate it in the fuse?
Thanks for replying.
Reuben

It will not take a Jetcat 80 due to its size, it can take any turbine in the wren 54 size . I am using a wren 70 which has loads of power for it and it allows the use of con-formal tanks which have been designed for the kit.

Presumably the fuel tanks are on the CG and the turbine is just behind the tanks...right? Do you have any negative effects with no full intake ducting?

The turbine is also on the CG with the tanks around it, the jet pipe is 900 mm long and we have no heat problems or need of ballast. I have done the same mod on the Jetwelt JP moving the turbine as far forward as possible on to the cg.

Just in case you were not aware, jet fuel, like petrol, destroys silicon which is why jet models use tygon and not silicon fuel tubing
