The difficulty I mentioned was most likely unrelated as I said in the post. The questions I was looking for answers were written before mention of the wing dip. I will copy and paste them and hopefully you will answer them one by one.

1 I would expect that the planes in the Tucson shootout would have dual receiver set ups, did the lock outs happen in both receivers at the same time?

2 What type of setups did the pilots who experienced the problem have in their planes?

3 How did they determine a lockout if they did not crash? the split plane method of installing twin receivers is common so if the pilots just lost one half and had control response reduced seems likely but I am grabbing at straws here.


4 you recommend reducing the length of the antenna and range checking, if the range is not reduced then the situation will be helped. If the range is reduced though will Futaba repair/replace the antenna for free?

Whether both receivers locked out in a plane at one time is an important question and should be answered asp, if that is the case then the problem is sensed throughout the aircraft, if it is not the case then it is localised and obviously due to an idiosyncracy of the position of the reciever.

I hope I have made my questions a little clearer.
thank you
