Default Weight of Cox engines?

I am adapting a Brodak .049 to work on several C/L planes designed for the Cox series of Bee engines. Anyone know the weight of a Baby Bee and a Golden Bee or Black Widow?

Thanks!

56 grams for a BB (older style, w/ tank and 6 x 3 TF nylon prop )
64 grams for GB w/ a TF 6 x 3 nylon
That's according to my Wal Mart special...(kitchen digital scale )

Thanks for the info! I think my plan will work. Now I just have to build a plane and try it out!

Should work fine. I'm replacing a BB Cox (it actually fired right up after about 18 years on the shelf and I had never heard of after run oil back then...) with a CS/Brodak 0.061 RC. Weights are very similar, I will get some additional weight from a better muffler and a throttle servo but it shouldn't be a problem with a modern radio in it...
