Building mine now- what a beautiful plane (especially for an ARF).
When you suggest extra epoxy, do you mean on the front for fuel-proofing or on the rear where triangle stock is?
BTW, for those who get a little anxious as I did, the pencil marks/holes on the firewall are supposed to be off-center (to the airplane's left) to align the engine properly (firewall is angled for right thrust).
I have an old O.S. .60 2-stroke with a pump (I can't tell the difference in power from my ST .90). From all that I've read, this should be ample power.
Darn, how long does that epoxy take to dry?!!!
