Space Bug conversion to free flight use

ticomareado Mon May 06, 2019 7:16 pm

There is a section on a set of plans for the California 1/2A Spacer F/F model detailing a tank plumbing modification which allows a Space Bug's rather inflexible integral tank/fuel system to be plumbed to run through a free flight fuel shut off timer. I was able to print out a very small and distorted image of that text and diagram on the model plans as posted in an Ebay listing for the model kit, but try as I may with a magnifying glass I cannot read it.

Can anybody help on this?

Thanks for digging that up for me, but I'm still confused.

Doesn't the new pressed in tube at "B" somehow or another have to make a good sealed free plowing diagonal connection on the lower part of the original fuel pick up passage ?

I'm having a hard time groking this thing.

It is all there in the image, I think. The original pick-up is inline with the needle valve (both would be facing towards the outside of the circle in CL) and it should be plugged at the end (marked with an A in the image) the new line is then drilled to intersect that line (marked with a B in the image).

Here is also a cross section (from Martin Hepperle's site):

Yes took me a min. to see the pickup had been PLUGGED then running the timmer through the external fuel hose from tank so it will feed from there . You get it Victory ?
