i would be very interested in knowing more about the ignition issues related to the DA 150. The DA ignitions are awfully quiet, and having been around them since their inception, i have never heard of anyone experiencing an RF problem with any DA engine - be it a 150, 100, or 50. not to say it isn't possible....just extremely unlikely.

i also seriously doubt that if you move the two servos back a bit it will have any real impact on your balance. the weight of a single (or two) servos is pretty insignificant in a 35% airplane. but the bottom line is that most of the pilots i know pay little or no attention to where things go - i have personally sat my ignition battery right next to my receiver and had three batteries within a couple of inches of the ignition module. i have friends that have throttle servos on motor boxes...no problems. a lot of so called "rules" are just rhetoric. the only "rule" that i personally subscribe to is the use of a PCM receiver in an ignition environment.
