Shaun, a mate gave me this setup that was in his old F-4 so I dont really know the history of it but the bearings feel glld, not tight and sandy, the piston has slight heat marks on it but no glazing I can see.
I spoke to an old school ICDF guy locally and he said somthing interesting. These intake may be causing turbulance because the wedge in the centre does not go aal the way back to the fan face, it could be causing the fan to cavitate- loads of noise with little thrust.
Now, I have a few options to test...
1. re-enstall the 95mm tube that gave about 6 Lbs on the scaleand hope that the forward motion will clean out the air into the intakes. I can only test this by actually doing hight speed taxi runs.
2. or make a splitter plate that seperates the 2 intake halves to just infront of the fan face.


On my old ICDF I do recall having intakes that went all the way to the fan with a splitter plate and a fairing for the spinner, even on my T-45 EDF with 90mm changesun it also has a splitter with the spinner fairing all the way to the fan face.....must be a reason for this?

I recall reading somwhere that these style of intakes I have now are similar to the "old style" That JHH used, I see they also now have the ones with the full splitter to the fan.

As for fuel. I had my local HS mix up a bru of 75 Methanol, 15% castor ,5% synthetic oil and 15% nitro. A for the plug I thing it isan OS 3 or 8
