Has anyone had a failure of the red cube fuel flow transducer? I move mine to the engine compartment down stream from the mechanical fuel pump about 75 hrs ago. Has preformed flawlessly and no more intermittent flow drops that possibly could be secondary to vapor problems. However, I took a day trip to Dallas today. 90 deg F temps. The plane sat on the ramp all day. Started right up, normal flow and pressures across the board. About 10 minutes into a 30 minute flight, the flow dropped to 1.5 gal /hr and stayed about there. No real change with turning on the fuel pump. Fuel pressure remained normal, recycled the electronics came back on with the same low reading. I haven't had time to open up the cowling. Acts just like the red cube failed. Any pointers?
Thanks

Quite impressive how strong the prop blast is.

Subject: Re: Outboard Tension Rod
Okay... here's what I've come up with... a shortened tension rod and a
custom washer made from j-channel. I don't think it's possible to get
the gap any better. I'm still not happy with the lock nut resistance.
I've got that question in to Vans.. and not happy that the nut isn't
sitting flat, but that's been determined by Vans putting the hole too
close to the bend.

Cool video. Static run-ups above 1700 rpm increase your risk of blade damage due
to gravel/sand.

Yes. I have one on my Mooney. Several cases of the wire leads breaking,
which depending on which one gives you high or low readings or none at
all. The leads need to be well protected from flexing and vibration.

I have the red cube mounted in my engine compartment too. I have 430 hours on mine with no trouble and within .3 gallons every time I check at fill up. I know in the directions that came with the cube, hard mounting to the engine can cause failure due to excessive vibration.
