I am surprised a sheet metal screw is sufficient. I figure a bolt and nut is not going to pull out.
What size drill and tap for a 6-32 bolt?

or, I could just use these (I think I read someone suggesting to heat the nut so it sets into the plastic?) [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&W=001603520&I=LXK048&P=K]bolt[/link]

Oh, and this is for a SSE which I believe has a flat bottom on the mount.

While we are at it, having read a billion SSE build posts, what is recommended for rear wheel? What Sig supplies? Or this [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&W=001603520&I=LXD851&P=K]Dubro[/link] or this [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&W=001603520&I=LXFV47&P=K]Sullivan[/link] ?? Seems lots of debate on this. I plan on using supplied main wheel bracket and likely a 11x6 prop (and at most 12.25x3.75)

and finally, I am amazed at pricing escalation. Someone posted SSE was $79 and raised to $89 earlier this year. it is now $109. Ouch.
