I am wanting some insight on how we might be able to create a vent line. We are currently building a 750 with the 130 and mini header tank. The video we have is the older one where there is a return line T-off from the pum back into the inlet line. We already have our wings built and they are the older version without a vent attachment in the top. I noticed that a guy named Roger was in the same situation and he ran what looked like drain valves that came out under the plane behind cockpit. We would maybe like to go that route but do not know exactly how he did that. That is really the only problem we are stumped on is getting a vent line from the mini header tank back either to the wing or make some sort of air bleed system as the vent return. Anyone have any insight or help?
"A lot of fancy good aircraft engines for sure. What Viking brings to the table is what now is very popular in a lot of new cars. Small / light / direct injected / turbocharged / all liquid cooled / not complicated / no exhaust pipes / inexpensive /…"
"Yes, those are the limitations. Getting more and more complicated. We are now testing other options as well
"Thanks Alissa, I'm currently at 18 degrees of pitch on the prop. I'm going to adjust to 20 to try to get closer to 5200 static RPM. I know there is more thrust in that engine and prop but I sure am happy with the initial number. And by the way, t…"
"The thrust might actually go up by lowering the RPM to 5450 if you want to give that a try. Super video and keep us updated!"
"545lbs of thrust with a Viking 130 and a 68” whirlwind spinning at 5700 rpm. I obviously have to adjust for a bigger bite but man that engine just sings. That’s a lot of thrust for a 770lb Savannah S. We did do a weight and balance today and with…"
"Has anyone monitored the earthX battery temp in the engine compartment? 140F is max from the Mfgr. They also said do not mount the 680 in the cabin. they have one that is vented but costs are much more, the 900 series that has two vent tubes. So th…"
