I remember one meeting at Sandane here in Norway.
I had a 12 channel MPX PCM rx, with a MPX 3030 tx.

We performed at test with two models at the same channel (64-35 Mhz) side by side on the ground.
Standing just one meters apart from each other, we switched both planes on to see what happened.
Antennas at their full lenght.

The other radio was a FM 6 ch Sanwa. What then happened surprized us..

Mine (PCM) was totally controllable, not fast acting and smooth, but highly controllable.
The other was in total caos.
Later this day, i saved my Byron F-16 DF, due to the capabilitys of this receiver, as someone accideltally switched his transmitter on.


Eddie, at what range do you think you will lose your model at?

At least 1000 meter, is no problem with IPD.
You would almost certainly loose it in a sight issue, long before it`s range issue.

Things are different on the groud, or close to it. App. half the range.

Btw, great tip about what happens too far out!
