Glad I could give you some help Wojtec, good luck on the conversion.
As far as the redundancy aspect on switching over to tailerons Peter, If only you know how MANY weak links a sophisticated turbine powered jet has... All my models have one common philosophy; simplicity. Just run through your model and count all the pins and sockets from all servo connectors, I think you might have more than a hundred which can all destroy our model when contacted badly on a single pin. What I mean to say is that all the extra's on board are additional things to go wrong (And they will, sooner or later!) Therefor I'm also the type that doesn't think of using electronic gadgets, gyros and other flying aids. When properly set-up has done ALL models will fly like a dream (Statement!). In my experience most crashes have a ghost-like atmosphere where very often a "probable" cause had been found, but could never be traced back because a hundred of other electric things reacted to the "probable" cause!
I fly model jets with taileron set-up back in 1995 and after a huge amount of flights from that date I have never had a single accident related to this.
