Fuel pump break in?

[cwbonner]

I am trying to figure out if the fuel pump on my Wren needs to be broke in or not? If it does please let me know your process for doing it,ie:how to keep the pump on and where to run the fuel lines ect?Thanks guys!!!

Also what are you guys running on pitch for the bergen turbine for a full 3-d setup?10 and 10? or more???heheheheeee

Carl...as I remember the manual says to run it in for a few hrs with 2.0 volts...other than buying a variable DC voltage supply I ran mine on 2 AA nicads for about 4 or 5 hrs...

just use a small fuel with a good filter install and just run the pump in a loop with clean fuel...this really is important...as the pump needs to be able to run on very little voltage sometimes...

I am sure others do it different ways but this works for me....

As for pitch...I am running +/- 11.5...at 1450 RPM...and 137K max on the turbine...

for what it is worth...
