Hi Arthur,
Don't know what the incidences are -I built mine as per the original Precedent plans (I believe SLEC uses the same drawings without the French notes).
A common feature of the model that a number of builders have noticed is that it needs a fair amount of down trim when the quoted C of G is used; therefore you could alter the tailplane incidence to reduce this effect - or you could build as plan coz it flies well in any case.

Thanks Dave
I have made the tail plane removeable so if the trim is a long way out i can ajust the platform so keeping the elevator level.
