Where I live, we have the second worst internet access service in the world, so I took my Garmin data cards to my daughter’s house in Peachtree City, GA, where the service is good. Just downloaded the navigation and terrain / obstacle databases. What a lousy, royal PITA, the Garmin web site is.
BTW, the operating system updates are not available to individuals. That is another reason that I have a love (using the equipment) hate (updating, getting answers, dealing with) relationship with Garmin.
Another work session today. While the crew cleaned the exterior, I noodled the trim system. I have a plate for such, but it is the wrong size. So I'll get two decals - "NOSE UP" and "NOSE DOWN" with appropriate arrows.
I realized I needed to finish up a few details in the forward upper fuselage before I can finish and insulate the firewall. Spent today making and fitting the rest of those little brackets so I can prep, paint, and install them.
Met today and discussed motor assembly. We have a deformed connecting rod! Also talked about the starter (bushing in flange that attaches to crank case very loose), alternator (busted fan blades may be trouble) and interior painting. Vacuumed paint chips out of the fuselage.
Primed the repaired surfaces with MIPA 2k EP primer. Since the workshop is a bit too dirty at the moment and I haven't everything in, yet, I decided to roll it on. Over the weekend I will sand it smooth and then apply MIPA 2k PU top coat.
Started easing into auto gas testing on the Rocket. Loaded up a mix of 60% unleaded regular in one tank and did a LoP cruise test followed by RoP and finally a "hot" takeoff and pattern. No discernable difference in performance. Tomorrow will explore an 80% mix, and ultimately 100% unleaded regular. Much testing to go, but so far the adjustable ignition timing and EFI are meeting my performance objectives.
It's whatever garbage "California blend" the corner gas station is selling this week. There is no doubt alcohol in it, but the chemical composition is mandated by season and in some cases by county. I can't remember the last time I saw a gas pump labeled "E10" in California... We really don't have a choice anyway. There are simply three grades of California junk, and it seems my engine will eat the worst of it.
Next time I'm at the pump I'll try read all the MSDS labels and see what it says about alcohol content.
Aside from a trained ear and a full engine monitor, no. They don't work very well on air cooled engines anyway.
Just got back from the "80+% car gas test" and it behaved fine. Cold TO and climb to 9500, LOP and ROP egt comparison, and a heat soak TO. No discernable difference except a 20 degree rise in cruise EGT on the car gas.
