I am going to re-direct this question since the YSSupport forum seems to be inactive.

I have been sitting on a 170 for a while now and finally putting into an airframe. What is the purpose of the foam fuel tank pick up supplied? (other than additional filtering?)

Will the Tetra bubbless tank work with this engine being it's vented instead of pressurized? I am currently setting up a standard Dubro tank since I am unsure.

This is not the CDIVersion although I am running the Sullivan programable glow driver (M060http://sullivanproducts.com/ModelProductsMainFrame.htm )since it's mounted inverted. Powered by a 6.2V - 2100mah LiFe pack.

Fuel is YS20/20 for break-in. I have cool Power 30%Heli available as well.

The above question and any additional tips appreciated. This is not my fist YS(They are all I use).... although my first run at the 'vented' instead of pressurized YS.

I am also looking at the Hyde Adjustable rail mount for use (non-nose ring) - Type AJ... since this going in a sport plane. Any info on this mount without using a nose ring is appreciated as well.
