Lots of grumbling on the Subaru boards. Summer is here, and many H-6 guys
are experiencing cooling problems. Three radiators now on some installations, driving the weight up even higher. One guy in Spain is hacked when he found the -9 he is building is going to have a 300 lb useful load with the H-6.
Funny to watch....northern customers say there are no cooling problems, guys in the south have to make partial power climbs and no touch and goes.
Airsube guys are talking about 6 ECU failures in various installations. Apparently the RV-6 crash in Idaho last year was an ECU "limp home"
failure precipitated by a sensor failure, which caused the engine to produce about 45 hp after liftoff. Partial power limp home mode can apparently be triggered when any one of a dozen or so sensors gets bad or no data.
Egg abandoned the belt drive gearbox after his off-field landing in Florida 2 weeks ago. He will now embark on his fourth generation gearbox, which will be a 2.05 to 1 ratio instead of the old 1.82. Interestingly this might cause a resurrection of the discontinued 4 cly engine on hopes that it might make advertised power on higher rpm. Weight of the H-6 also seems to be triggering a resurging interest in the four cyl motor.
