I am in the process of renovating an old 80's, 26" span CL trainer for my grandson, which was a construction article in a copy of MAN back then. It was originally powered by a Cox .049 Baby Bee which after countless flights teaching my son and several of the neighbourhood kids to fly, has done its time.

I plan on using a TD.049 with a 2 oz. wedge tank, but having forgotten most everything regarding CL planes, I need to know where should the tank outlet be in relation to the engine's needle valve and how far away can the tank be located. Thanks
