The sky was on fire last night

Took Dilemma out yesterday. Parked the airplane and went to grab the towbar. Looked back at the plane and had one of those OMG moments.

Keep pounding rivets, running wires, sanding fiberglass and asking questions. It is well worth it.

Nothing better than the sun setting over a fuel truck full of the elixir of life!.

What kind of numbers are you getting with the 4 now Axle?

Still tuning and breaking in. The new inlets and diffusers are not fully completed. I also had to upsize the inlet rings. This plane has basically a new complete FWF set up.

The new intake i designed is only dropping 0.1 inches below ambient MP reading at start of take of roll so i think that is working well. I can go on and on but you probably want to see numbers.

Not happy yet. But close. I have been working on the bush plane so this one is slowly being tuned.

194 KTAS on 9.9 is a good pair of numbers. You're about 100 ROP there?

Tell us the new inlet ring diameters.
 
Dan, will give you the accurate info soon. I am trying your method of large inlets. Same diameter rings sam james uses on the RV-10. I went from 24.8 in^2 total to approx 48 in ^2.

Yes 100 deg ROP on that pic.
