Hi David.

Why do we need opto-isolators......

Good question, but after the GREAT ball of fire I saw a few week ago with my Gripen, I want to aim for the paramount of safety. (! ! A awsome scene..([&o] [>:])

I tell you all, this was not a bedside story for my children.... Not at all.

As I understand you David, I don`t have to worry under any circumstances, after installing the PowerBox. Correct?

I now have 2 x 3200 Kokam on RX through the PowerBox, and this is surely a improovement. After all..

BUT, I want to reduce the factors to a minimum, wich a opto-isolator would do, in addition to the P.Box..

In some countries, they say PCM is the best, another can report PPM is the max..

Example: Norway is best on PCM, Denmark is PPM, Germany is the best at PCM again..
We must take the experiences amind, and bring them futher on.

I know MPX claim their 12 Ch IPD receiver to reconize a 2 MV signal..
This doesn`t matter at all if the signal is (and other signals as well) , are twisted to a recognizable frequency, due to mountains, walleys + +.

I just don`t wan t too cause a incident/accident, due to the set-up in my models.

Norway is the leader in sophisticated equipment for personal use in the world.... We have the world record for the number of cell phones per citicent, the record for link-antennas, almost on every hill you can see.
The mountains here Nort West can make interference, unrecognizable to the keenest on this subject.
Glad the mongest of the Jet Jockeys her in Norway are at the flatlands. ( Fagernes Air Show is at a none subject)

If I were you David, I`d think at least twice to make a lift-off on the site where my Gripen went down, with your splended AD Hawk.. Ten years since I had a severe interference issue here, and this was with a AM from Simprop..

PS: The idea about a opto-isolator on a Power Box, is a best buy for me.. How about you..?
