RCIGN,
I have a question or two,
I have a ZDZ-80 & 50. Both have E/I Last weekend one of my friends ( who also has an 80 & a few of us share a big Hots to break in engines) was on his second flight when he lost his throttle (went to 1/4 or idle) and ended up mostly crashing the Hots. He was told by some of the other guys that he should not have had the throttle servo on the firewall as it got RF from the ignition. I had set the plane up for the 80 and flew 4 gals through it with no problems. He had exactly the same set up and went 'boink'. I am using an Airtronics Stylus on PCM and he is using a Futaba 8 ch on FM (both of us are using Hithech servos). Do you know what gives?
Part two: (Same Radio, same type rec)
I have my 50 installed in a Pica P40. 1800mil batt's for each for the rec and the ign. they are up near the front behind the engine compartment the ign batt is by the ign unit on the starboard side, and the rec batt is on the port side. The distance between them is approx 6". However, both power wires run to the top of the comaprtment and back through a tunnel to the switches (which are about 1" from each other) in the radio area. The switches are approx 6-8" from the reciever. I have one flight (due to weather)on the P-40 and did not experience one problem (yet?) with my set up. I'm a Mechanical Engineer (not Electrical) and I thought the only RF would come (or originate) from the Ign unit and/or the lead to the plug. I have since been told, that it will migrate through all the connections back through the switch harness and batt pack. If this is so, I presume anything adjacent to those wires will be exposed (which would be my other swich harness, and the wires running up to the forward compartment (rec batt)) to RF.
Boy, oh Boy, Am I confused now.
Atmospherics may play a part occasionally, but how come I'm ok(so far)???
