Alright guys, over the winter this forum became a little dry and some of the posts heated.

Time for some fun and knowledge.

How it works:

First question – How many blades had an F6F-5 Hellcat Propeller (for an example) – Then it’s your turn to answer. Then who ever asked the question name the next guy who asks the next question – and so forth.

Rules:
Only warbird related questions model or full scale.
Two part questions are allowed.
The time limit between announced winner and your question is 24hrs

Rule change Feb 26 2010

Alright here is my question:
Question #1
What is that and for what is it for?
