OK guys help me out. I need a sanity check. We lost the twin to my Macchi today. I'm pretty sure I know the cause but would like some feedback from you guys who have been racing warbirds for a while.

So here is the question. How much torque would you be running on the elevator of a 5 lb .40 size airplane that does just a little better than silver speed? Would you use a stock plastic arm? Those who saw my Macchi fly at the Last SAMs race tell me how you would equip,
