My Quark build is coming along pretty well (though I'll post some photos below so you can tell me what I've done wrong!).
Two pressing questions as I'm on the tail and fin:
1. Do people glue the tail(s) onto the axle and incidence rod through the bellcrank? My inclination would be to keep the tail removable, if only for ease of repairing (not that I intend that to be necessary!) and travelling, but if so, what's the best way to keep it in place.
2. After dry-mounting the fin, and cutting through the stringers, I realised that the fin and rudder will be supported mainly by the tail end of the fuselage - behind the incidence pin slot. This isn't as rigid as I would like because of that slot, and the lower part of the fin (that straddles the upper part of the slot) has got a fair amount of give in it so isn't a lot of help. Should I be worried about this? I'm somewhat inclined to sheet the fin with 1mm balsa, cross-grained with the base of the fin, but don't want to add any more weight than necessary.
