Here's what I came up with for round two. So far...


Jim

So you enlarged the venture to where it needs a bladder tank? And it worked?

Well, I guess congratulations are in order!!  CONGRATULATIONS !!  As for posting, okee dokee .... while I was waiting for your response I built and completed three planes for the event.  I'm hoping to get to fly them someday soon once I figure out how best to video and time them. 

Hey, Congratulations Jim! I guess you have been busy.

Paul, yes the bladder works great. I used one on my Reed Speed Mustang. I used a Killer Bee backplate with a fine thread NV from one of the old Cox postage stamp backplates pressed into it. Or it might have neen one of the ones from Texastimers.com, same thing. It's harder to flood than a Tee Dee because if you slip and let the fuel flow too much, most of it just spills out the back of the engine. Fill the feed line, one good exhaust prime and it's first flip cranking every time, once you figure out where to leave the needle. If you don't have a KB backplate, you can bore one out. It's not critical as long as it's not too small.

Here's my Mustang

Thank you Rusty and Jim!

Ditto what a Rusty said above. The only thing I would add is that it is critical you use the smallest fuel tubing available or you will flood the engine.

Time to post photos on CEF if your going to compete. Here's what I have:

Here's what I built for the races! The build of the 1949 Lawrence Institute of Technology G-1 can be seen on CEF.
