Default Red cube install beside spider

Hello,

I am going to install my red cube and have some interest to install it between the fuel servo and the spider. For those who choosed the same location, I would like to know if they experimented some "Vapor Lock" because of the proximity of the hoses between the cylinders.

In advance thank you
Sylvain

My FF transducer is mounted directly to the flow divider with a NPT nipple. Can't get any closer than that, and I have not seen any issues with vapor lock or inaccuracy.

The cubes I have seen mounted under the cylinders, and plumbed between the servo and spider have been covered with fire shield. That is my plan. Good question about experience, though.

I would suggest you review and follow the guidelines in the EI install manual:

I've got mine like Michael. Pipe nipple, no sleeving. Its right up front center, so it gets whatever cool air there is coming in. Accurate, stable. Mine is a floscan, but same difference.

WE have several flying examples of cubes mounted at or near the spider. We havent heard (in 2+years) of flight time, of anyone having any issues, vapor lock (that was traced back to the location), or any failures. Flow readings have been consistent with those in other locations.

Default Fuel Servo - Distributor

Mine is on a piece of aluminum (wires UP as specified) in front of the sump. No vapor lock issues.

FF readings do not fluctuate as they did with the FloScan transducer in the tunnel.

See the red cube config Rob Hickman uses (pic in the AFS manual).

Sylvain,

We mounted ours there and have 40 hours on it now. No issues, hot starts great, no rough running engine after hot start. Angle valve engine. Fuel flow indicates normally at all times, very accurate.



Tom at TS Flighlines made us up the hoses you see here, great service.

Call EI. They will tell you to mount it there. That's what they told me and 350 hours later it's working great. I won't say I do not have hot start issues though...but I suspect it's the same as every other injected engine with a tight set of baffles. That said, it is one more thing to heat soak up there on top of the engine.... She always starts..but complains about it.

If I were to build again, I would put it in the same place.
