RE: PowerBox and Opto-Isolators.
Gudmund,
That is what I thought having looked closely at the Powerbox spec for an RCJI review but I am no expert on these matters so I was interested to know why you thought they were neccessary. I was certainly NOT critical of your intentions there, if thats how I came across.
My experience with the Mig 29 seems to bear out what Powerbox claims, it has extraordinary ground (and air too I presume) range and I feel comfortable I have the best possible equipment on board, and I am using the same on my Hawk. I had been planning to use fiber optic signalling to the tail servos on the Mig (even bought the units) until the Powerbox system came along.
I also heartily endorse your belief that we need a MUCH more reliable RF link for these expensive models. Lets hope such a system arrives sooner rather than later.
Regards, David Gladwin.
