I have a Wing Thunderbird AMF 54" that came with a 49" endless loop string with no twists in it. The current brace height is 9". I'm thinking it could be the factory sting. Is this the normal brace for these? Thanks

You want closer to 8 to 8 1/4 for that bow, in my opinion of course...8 1/2" would be as high as I went. But shoot it at 9" and see what if feels like to you. Brace is a variable anyhoo. :)

Yes but might be ok at lower, too like 8-8 1/2”.

Thanks guys. I'll give it a try as is and then I'll get a normal 50" string to find the sweet spot.

I built a 50” string for mine with a brace of 8 1/4-8 1/2”. Perfect. Awesome bow by the way

I looked at the old vintage catalogs as suggested. Only year I found suggested brace height was 1975 = 7 1/4" to 8 1/4". Thanks

So the correct string length for a 52” bow would be….. ??

There were two versions of the Short Thunderbird. The early ones were all 52" or 62". Then in the mid 1970's AMF decided to change the length on them to 54" and 64". Not many made at these lengths.

The OP is talking about a 54" Thunderbird which would use a 50" B- 50 string to get proper brace.

The earlier 52" Thunderbird(way more common) would need a 48" B-50 string. Brace heights about the same for either bow.

Thank you, sir!

My first bow was a 62", [email protected] Wing "Thunderbird" purchased in 1970. Smooth as silk. It was also a great looking bow. Used a B- 50 string, not fast-flite combatable. Unfortunately it delaminated around 1975/76. Great bow design. Way ahead of its time. Bob Lee was one of the best. His son, Rob, still runs the family business, today.
