4-40 or 6-32 control arms?

[Ed Miller]

If you can find them, 6-40 are better, finer thread. I've been using Dubro metric socket head bolts ( can't remember size ) with the heads cut off, again finer thread than the 6/32.

  Ed I wouldn't do that especially on ailerons. I have had 4-40's snap off like twigs on 90 sized models before. The vibration kills them.
