  OOPS,something else, how do you set them up???

They need something on the airplane to keep them from flopping around.  The canopy on the Firebaby is for this.

I used to make them this way.
Get a small balloon, probably from a party store.  Then with either a piece of hard wall plastic tube or fuel line with a piece of brass tubing inside at a place just short of the balloon length, wrap a small rubber band or copper wire to seal the balloon to the the tubing.  Hook fuel line long enough to reach the engine.   Then with the airplane vertical, nose down, fill the tank with fuel until all the air is gone.  Important, don't stretch the balloon.  Pinch the line and hook up to the engine.  Atmospheric pressure provides the "push" along with suction from the engine.

Hope this was what you were looking for.

  Thanks Don, I appreciate the help.

Beautiful, just gorgeous!!!! I have such a deep affection for the first FireBaby, my Dad taught me to fly CL on one with a Baby Spitfire (which I still have) He put me on his shoulders and my older brother launched for me, flew a couple aided flights and soloed the same day, I was 6. That was in 1956.

The only real thing I felt I missed out on, the Firebaby. 1949, asked Dad for a Firebaby, they had a large stock at the LHS.
We had been ROG'ing A-J Hornets, but Dad was of the mind that "Gas Motor Planes" were of the O.K. Super .60 variety, period.

Every time I see the Christmas Story air, Darrin McGavern's voice rings out with Dad's squelch: "You'll CUT YER FINGER off!"
Sadly, he was killed before we ever got into I.C. power... Luckily, I was 'sponsored' by kind older friends that took my Monogram and Strombecker talents serious.

I did get a repro Firebaby from Frank Macy years later, in '82. One of my most memorable characters.

I have a few copies of the original plans if anyone is interested.

I built a Firebaby from scratch. Plus made extra kit also. I made my own graffics and not as nice as one posted but not bad. I got copies if templates for bi-version and made parts for such.  Just need to add top wing and good to go. I also made rubber band AJ Pursuit. Did graffics also. Used good colored markers from local craft shop.
Thanks Ty for copies of templates. You da man !!

That is a beaut)))))))
Shug

I have an original in need of restoration.
Thanks for the ideas and inspiration.
I have the original OK Cub as well as a brand new commemorative on that I was able to get just before they quit the model aeroplane business.

For what it's worth Ebay has new FB motor mount.  https://www.ebay.com/itm/133904795537?hash=item1f2d590791:g:S4cAAOSw~~5haaz1

Very Nice reproduction , you put a lot of Fun into the model > have you flown it yet ( i know it winter here ) but some days 50 F ant bad 

This is what is needed to get grandkids or even beginers started.   It was my first control line plane I tried to fly on 15 foot dacron lines.  I have found my original kit of the Scientific American Boy.   May ahve to go dig it out when done with present project.

Eric sorry so long to reply. I haven't looked at this thread for awhile. I have not flown it. It turned out to be a hangar queen. I did run it though. It really was a fun project.
