RE: Venus II
As a beginner I struggled with the tank at CG and the pump - too many variables for me. Installing tank at CG is easy to do later once you get the plane flying properly and the engine running well. I now have tank in front of plane and pump on the shelf.
I learned from a pro at my last pattern meet that the best way to set up a pump is to get the engine dialed in without it - find where the needle settings are then tune the pump to the dialed in engine. Makes a lot of sense, but would in this case require the engine being broken in with fuel tank in front of plane, then moved back once engine is broken in.
This plane kicks a**.
