GreatPlanes PT-40 MKII the manual says to mount the stab,fin,dorsal fin before covering
the plane I think it would be easer to put the covering on the stab and fin leaving bare balsa
where it's mounts then mount it to the plane last. what do you think?

I cover first mount later

I mount first, cover later

So it's really your call

I mount and then cover. Look through my LT-40 build thread and you can see how I do this. [link]http://www.rcuniverse.com/forum/m_3439708/tm.htm[/link]

learned a lot from your LT-40 build.
need to Cut the dihedral on mt GP PT-40 the LE, TE, and spars all need to be cut at an angle I used the guage
to mark the wings but how do I make the cut straight don't want the dihedral to be right but have a delta LE.

I used a razor saw
