John,
Tank is 2 oz Sullivan, only two lines , (1) brass feed line and surgical tubing to clunk, (2) fuel fill and "ram air" , line terminates in the "bubble on the tank. Fill by pointing nose down until desired amount of fuel is seen in in the tank or as measured from syringe.
I dont believe this will work w/ the AMD confi guration as they do require more fuel feed pressure than my Pathfinder config. will provide.
They do make a backplate with a pressure tap that I have not tried, might work!
I do use bladders on my 1/2A Barecat. There is a pic of it in the photo gallery section. district 5, 2nd row from bottom, left side (blue and white) Also pic of one of my Pathfinders , 16 rows up from bottom, right side .
Both are very capable performers.
Note: I do a dry assembly of my Pathfinders to get cg location. They normally build nose heavy. I dont like to add weight to a 1/2A if it can be avoided. I normally shorten nose 15/16" and cg is in area of those on plans. Never have added nose or tail weight for balance. Finished model without fuel normally weighs 11 oz.
Any other questions, please ask
Roger
