Was concerned with the issue of wiring the servos. As I read it, you are suggesting putting two servos, say on the LHS wings on one channel and the two servos on the RHS wings on another channel. In that case reversing is not required. However, it is not possible to do that physically. [8D]

As I see it, each wing becomes one unit. So if I were to use one y-extension for each wing, I would connect the top LHS and RHS servos to one channel for the top wing and the bottom LHS and RHS servos to another channel for the bottom wing. Only then would I be able to store the wings seperately and then assemble on field. However, this would cause both servos to turn in the same direction. Since they are opposed to each other in terms of installation, when one servo in one wing raises the aileron, the other in the same wing lowers the other aileron. This satisfies the "aileron" function so my mentor is right about that. But it also means that I will not be able to use a flap function. Also, that way I still have some control if any one of the connectors fails (EEK! What am I saying)[X(]

Then again for this kind of airplane and its handling characteristics, I will not require a flap function, isint that correct? Just thinking aloud here

With respect to servo arms, I dont like to fly very fast so it is not likely that the nylon arms will twist over. Just wanted to know whether the length in those arms is sufficient as to what the manual recommends.

I am also thinking whether 75AX or FS91SII (have both of them). That would be a whole can of worms to open, but if I do decide on the 75AX, I will need the muffler extension adapter to allow the stock muffler to clear the fuse. The 75AX gave me some issues with keeping it running last year on a certain airplane. But I think it may have been a tank height issue and fuel type on that specific airplane (have kept it oiled and sealed and never used synthetic on it since we moved to synthetic-castor blend, Klotz-100, a bit later). They weigh almost the same and will turn the same prop and drink the same amount as well. What is your thinking on the same?
