Hi Rusty,
<So if you get cold enough, you will actually speak to the list :-) >
Yes and I got a lot of great ideas. May try yours first as it seems to require less work and will not keep me from flying. Seem to have excess cooling capacity as on these 40 degree days neither the oil or water temps get above about 150F. Been thinking that with a 4inch shorter oil cooler your setup could easily become a FWF assembly for the RV-3 and 4.
<So how many hours do you have on the plane now? >
Only about 22!!!! However, now that I have quit doing things to it and have it painted it will get a lot more. One of the things I did was to install a fuel valve from a Cessna 210 which is a double valve to allow excess fuel flow to be returned to the tank you are feeding from. Works great on the T-210, however, in this application there is a need for a small accumulator as the engine quits no matter how fast you switch tanks! So for now I switch tanks at idle power.
Still have that vibration. It seems to have something to do with power as I can dive at all speeds up to 200mph indicated and don't have it. Under power it definitely increases in intensity in a skid.
Have had the prop balanced and while at it we checked the engine at the flywheel both are very smooth. Both prop blades seem to have the same pitch at respective positions on each blade. Even tried a Prince prop. No change.
Congratulations on the RV-8. Look forward to a picture of two. May even pop down to see it sometime when you are going to be at the airport.
Happy Turkey day
Rich

Wondering what others are doing for cockpit heat. Like to find something "quick and dirty" so the plane is not down until summer when I won't need it :-).
Hi Rich,
So if you get cold enough, you will actually speak to the list :-)
How about attaching a scat tube at the rear of the right cheek evap core. This would give water heating, with essentially clean air (good CO monitor always a good idea). Ideally, you could use one of Van's standard cabin heat valves on the firewall.
Tracy and I also discussed using the cheek area for heat inlet to the cabin. If there's no room on the firewall, you could route the scat tube to a flange on the front bulkhead of the cowl cheek extension, then create an opening on the cabin wall inside the cheek extension area. You could put your on/off valve on the inside cabin wall. You may need a way to keep the hot air from blowing directly on your avionics though.
So how many hours do you have on the plane now?
Cheers,
Rusty (2.1 hours of non-hmmmmmm)
