I have just assembled a great planes viper which I have been told is a 'predator' and simply screwed the vee tail on and flew it- absolutely no problem so can only assume the 'seat' as glued in is ok. granted it dosen't look right but as some wise man has
previously said the taper in the fuselage will mislead you. have checked my transmitter trim and absolutely ok,
