Title: Forerunner CG
Post by: Chris Belcher on August 05, 2013, 10:35:13 AM

Anybody know where the CG should be for the original size Forerunner (46)...got one ready to go up. Total weight (unless CG needs adj) is 43 oz...should be a good flyer.

The Custom Model Plans show the CG at 2-1/2 from the leading edge at the fuselage ... Hope that helps ...

will do...I haven't permanetly mounted the tank yet...can't decide what to do...plastic clunk or metal. The motor is LA46 with small FP40 venturi and needle valve. Have run 1/2 galon of fuel through it. Sounds ready to go.
Any suggestions on tank?

The Custom Models kit uses a plastic clunk.  Fits perfectly in the fuselage cut out.
