Success !! Having COMPLETELY purged the sack in the UAT using the procedure I described 4 days ago (vertical UAT and using the engine fuel pump to clear any air WITHOUT running the engine) I ran the RAM 500 and had four completely succesful flights with the StarJet today. Clearly the key to success with this device is proper purging, so if you are having problems with the UAT give my purging procedure (essentially the same as Tom Antflinger's) a try, it works and without the frustration of running the engine with, possibly, several flameouts whilst the air is being purged. Time for BVM to review the instruction sheet ?

The Starjet /RAM 500 combination impressed evryone who saw it fly today, incredible acceleration and vertical performance combined with superb low speed handling, it was a delight to fly.

I just built a couple of the "Eddie Weeks" style pleated paper filters using an 8 oz. round Sullivan tank and found a couple of Fram paper filters at a local Pep-Boys store that fit... here's the the Fram part numbers for reference:

1" Long for small (4-6 oz) tanks: F10157, $1.59 ea.

2" long for 8-10 oz. tanks: F10158, $1.99 ea.

Assuming that the comment that the paper filters will supply fuel even if the filter is 95% exposed to air is true, the long filter seems to be the way to go, allowing the header tank to be drained almost completely before running dry. I Aeropoxied the pickup tube to the filter after removing the one-way valve/rubber fitting...found that the filter fit much easier into the tank neck after using a belt sander to grind the rough edges/"bulges" off of the metal ends of the filter (wrap the filter element with tape to keep any metal particles off of it).

Sorry Woketman and thanks for the correction.
