Hi Rusty,

Yes and I got a lot of great ideas. May try yo= urs 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&nbs= p; neither the oil or water temps get above about 150F. Bee= n thinking that with a 4inch shorter oil cooler your setup could easily bec= ome a FWF assembly for the RV-3 and 4.

=0AOnly 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 d= id was to install a fuel valve from a Cessna 210 which is a double val= ve to allow excess fuel flow to be returned to the tank you are feeding fro= m. 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 swi= tch tanks! So for now I switch tanks at idle power.

Still have that vibration. It s= eems 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 defin= itely increases in intensity in a skid.

Have had t= he 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 a= t respective positions on each blade. Even tried a Prince prop. = No change.

Congratulation= s 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.

Wond= ering 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 i= t :-).

Hi Rich,=0A

So if you get cold enough, you will actually speak to the lis= t :-)

How about attaching a scat tube at the r= ear 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.&nbs= p;

=0A

Tracy and I also discussed using the= cheek area for heat inlet to the cabin. If there's no room on the fi= rewall, 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 t= he 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 f= rom blowing directly on your avionics though. =0A

So how many hours do you have on the pl= ane now?
