14 MZ, need help.
Hello
I need any useful reviews of the problem happened to me for second time.
The last accident yesterday in a PITTS-Stinker of Camodel of 2 mts. And another 4 months ago another Pitts. On the first flight of the day the plane.
Those aircraft had flown before without a problem.
Futaba 14MZ Radio
The first airplane pitts, with Motor ZDZ 40. PCM Receiver Futaba FP-R138DP
The second Airplanes ZDZ80 Futaba R607FS FASST Receiver 2.4GHz
Receiver Batteries and Power in New Latest 2.8 Amp loaded, and post accident were to check them full load.
Switch Heavy-Duty receiver.
Plane all digital servo high torque.
Cables and extensions all Heavy-Duty.
In both accidents the aircraft will pass the same problem, with zero response, without any demonstration of interference. Only the engine was on, no change in acceleration, frozen controls, until it crashed.
I would note that I do not think is problem of radio, (TX) because i use in 50 other models that I fly with the same radio and smoothly, all weekend.
Any opinions useful, I would be grateful, because according to this accident I dare not fly a gas engine. It costs nothing to cause a disaster .........
I am really very worried, knowing that step.
Thanked from and to all.

RE: 14 MZ, need help.
We'd not know why two different airplanes, with two different setups would crash in a similar manner. Something may be common to both...usually, complete loss of control is in the power system of the model. If the power system could only deliver 2.8 Amps, then it's possible that the battery voltage was drawn down when that limit was exceeded. Operating several servos in a large model can possibly exceed that amount by quite a bit. That would cause a severe voltage drop and then the receiver would stop operating due to low voltage.

All indications are that the battery was not able to deliver voltage in a pick of most consumo.
Well were 8 high torque digital servos.

Bax,
The separation between the electronic of ignition and electronic of the plane (servos), is important?

BAX,
PLEASE TELL US ABOUT THEESE.

RE: 14 MZ, need help.
You want to keep the receiver and its antenna as far from other wiring as possible. That includes servo wires, battery wires, and ignition wires. Ignition wires, especially, because they can emit a fairly-strong magnetic field around them if the shielding isn't perfect. That can affect almost any airborne system. Usually, you want the ignition wiring as far from any other components and wiring as is possible.
Bad servos, bad connectors, bad switches, and bad battery packs can also contribute to erratic operation.
